Caring For Cactus In Winter

Most cactus are usually dormant during winter and active during summer. However, some are active during winter. Christmas cactus and Thanksgiving cactus bloom in winter. We know how unfriendly winter can be, and your cactus needs to be taken care of with caution. I sought to find answers on how you can care for your cactus in winter, and I made some pretty exciting discoveries.

Bringing Your Cactus Indoors in Winter

If your cactus has been outdoors during spring and summer, you need to bring it indoors in cooler weathers. This way, your plant will gradually transition without having a ‘shock.’ 

  1. Move your cactus to a shade outdoors, which receives about one or two fewer hours of direct sunlight daily for 1-2 weeks. Do this just before winter when the temperatures are expected to be below 65F at night. 
  2. Move the plant again to a place that receives one of two fewer hours of sunlight as compared to the previous place. 
  3. The idea of moving the cactus gradually is so that it gets used to the temperatures for it to avoid the ‘shock.’ Take the cactus indoors and find a sunny spot. A south-facing window would be perfect. Try keeping the cactus warmer in temperatures of 65-90F. All this is in preparation of winter dormancy.
  4. Make sure you don’t fertilize the plant during winter because it is dormant.

You need to bring it indoors in cooler weathers.

To encourage your cactus to go dormant, you need to reduce your feeding schedule to make it less. Don’t water frequently but rather do it possibly once a month. 

Caring for your Cactus Indoors in Winter

1. Place your cactus strategically 

As mentioned, it is advisable to bring your cactus indoors to avoid the harsh winter conditions. Some people opt for different types of grow lights to provide ample light for the plant. However, unless your home is extremely dark, it may not be necessary to purchase these lights. 

Place your plants strategically at a place where they will receive the most light as possible. The light should be sufficient enough to keep your cactus colorful for the few cold months. If you have more than one cactus plant, keep rotating them so that they all get enough light. 

If you are in the northern areas that experience some harsh winters, don’t place your cacti too close to the window. The cold coming in maybe too harsh to them and they may end up not doing very well.  

2. Grouping your plants

If you are a massive cactus lover, you may probably have a collection of different species. As mentioned earlier, some species are active during winter. The idea is, initially, if you started growing the cacti from seed, you should have probably labelled them. Even when you propagate using cuttings, labelling is essential as this helps you know the particular needs for the plant. 

Know each of the plant’s water and light requirements. Cactus are quite sensitive to overwatering, and you need to water just the right amount. You don’t want your roots rotting slowly and the cactus eventually dying. 

Group them in sections of those active and dormant during winter and their different light requirements. That helps reduce the possibility of making mistakes during their feeding time. If you are not quite sure about the schedules, there’s a lot of research online that has been done on different species. This would be resourceful.

3. No feeding and less watering

As cacti are more prone to rotting as compared to other succulents, proper care needs to be taken to avoid such incidences. Some common signs of root rot are black or colored dots on cacti skin, discolored scabs, sunken spots, and you may even see some oozing of the cactus. 

You need to take into consideration what happens below the soil which you can’t easily see. Cacti depend on the root hairs to provide nutrients. If they start rotting, that means nutrients are not readily available, which drives the cactus to the above signs of root rot. These plants can take some underwatering for some time, but overwatering is pretty bad for them.

Keep the water levels low and only water when they really need it.

Keep in mind that you should keep the roots happy when watering. This means just enough water to prevent them from drying. Since most species won’t flower in winter, that means the growth rate will be pretty low. Therefore, they just need enough water for survival. 

Also, avoid feeding them. Don’t use any fertilizer at this point as they may end up becoming weak. Keep the water levels low and only water when they really need it. You can use a wooden stick to poke the soil until the lowest point before watering to see if the soil is still wet. Only water when the stick has no soil remains to stick on it. 

The issue of watering is quite sensitive. If you adhere to the above, you might find that your plant only needs water once a month or even longer. Be careful not to underwater such that the soil starts to pull away from the sides of the container. The roots may end up desiccating and collapsing.

The pot you use is a huge determinant of the plant rots. Get a suitable container, preferably terracotta pots that have drainage holes. The importance of these holes is to ensure that any excess water is drained away to avoid water sitting in the soil for long. 

You probably are aware that even the soil you use is a major determining factor how your plant thrives. There are readily available cactus soil mixtures which you can purchase in local garden stores. You can also order online, and they can be delivered to you. Make sure the mix you go with has some coarse sand and vermiculite. The soil mixture and the pot work hand in hand to ensure your cactus doesn’t die of root rot.  

4. Choose your cactus wisely

Purchasing cactus should not be complicated. However, make sure you choose the best species, one that works for your environment. Some cacti species are more tolerant to the freezing temperatures of winter compared to others.

Make sure you choose the best species, one that works for your environment.

Consider choosing a cactus that will survive through winter. At times, you may need to cover your plants to retain air and moisture to prevent ice from destroying the stems and trunks. 

Some types of cold-hardy cactus

  • The Claret cup cactus

This particular species is from the Echinocereus group. They can withstand temperatures of -20 degrees Fahrenheit/28 degrees celsius. If they are indoors, they can even withstand lower than that. 

  • Mammillaria Bocasana 

This type of cactus belongs to the Mammillaria group that are usually ball-like. Once they mature, they can form rolling mounds of tiny bits of cactus. They can withstand temperatures as low as -20F. 

  • Opuntia

Opuntia is also another group of cacti that’s cold-hardy. Prickly Pear is the most common type in this family. Not only is it among the fast-growing cacti, but it is also drought-tolerant, which means it doesn’t need frequent watering. They grow to an approximate height of 12 inches. 

  • Pediocactus 

One of the popular types of this family is the Mountain spiny star. They are ball-like, and they have a high resistance to cold. They also have the potential of growing up to 12 inches high.

  • Escobaria

Lee’s dwarf snowball, plain’s pincushion, and beehive cactus are some of the popular types in this category. They are very tiny but produce big flowers. 

5. Insect management

Homes will tend to be dry during winter. This is because there are all kinds of heating systems to keep the house warm from the heaters to the furnaces. Insects such as mealybugs love warm places and are most likely to attack your cactus.

Insects such as mealybugs love warm places and are most likely to attack your cactus

It is natural for you cactus to be insect-infested. What you do to manage them is what matters.

Mealybugs

They are usually ⅓ or ⅕ inch long and resemble cotton as they appear waxy. Mealybugs are usually in a cluster and move slowly. They are mostly found on cactus leaves and other hidden parts of the plant. 

We also have root mealybugs that suck the root juices and live in the soil. When they suck these juices, root rot is almost nearly inevitable, and they end up causing bacterial infections.

Fungus gnats

They are usually ⅛ or 1/16 inch and look like black flies that can easily be confused with mosquitoes. Mostly, they hover around the soil surface. What’s interesting is that the adult flies can’t harm the cactus, but the larva is pretty dangerous. The larva lives in the soil and consumes both the roots and organic matter, which are meant to provide nutrients to the plant. 

Fungus gnats are more likely to affect cactus seedlings as compared to fully grown cacti, and they may end up killing the young seedlings. 

Spider mites

The first sign that spider mites infest a cactus is the webbing. You will also notice brown spots on younger plants on the epidermis. In terms of size, they are about 1/50 inch. If you try tapping the affected area, they look like dust. They suck the plant’s juices.

Scale

Scale insects, just like mealybugs, are cotton-like and they attache themselves to leaves and stems but can be scraped off.

Try and control these insects so that they don’t destroy your cactus. Get a safe remedy. First, to avoid the attacks, you need to grow your cactus in the right conditions. Make sure if it’s winter you ensure they are getting just the right amount of heat and light. 

For spider mites and mealybugs, you can wash them off. Cover the soil you’ve planted your cactus in to avoid it being washed away and pour a lumpsum amount of water on the plant. The insects should be washed away. 

Consider spraying the plant with a dilute alcohol solution of 1:3 with the ratio being alcohol to water. 

Prevention is better than managing the insects when they have already attacked your cactus. Hygiene should be a priority when growing these plants. Always be on the lookout for dead leaves and discard them as they are a hot breeding ground for pests. Keep your plant in the recommended conditions such as the right sunlight and watering them only when they require the water.  

Caring for Christmas Cactus in Winter

Like previously mentioned, unlike most cacti species that are dormant in winter, the Christmas cactus is active at this particular season. 

The Christmas cactus prefers bright but indirect sunlight. If you decide to grow them indoors, protect them from the southern and western sun exposure. They do well in warm temperatures of 70-80F. 

During winter, try to keep your Christmas cactus in the evening at temperatures of 60-65 °C. It is more likely to form buds in temperatures between 50-55 °C.

Christmas cacti love humid environments.

A word of caution is to avoid putting them in cold drafts and also keep them away from home heaters or fireplaces. Remember to fertilize them in spring when growth appears. 

Christmas cacti love humid environments. For people who live in arid areas, it’s essential to keep your plant moist. The easiest and best way to do this is just placing a tray of water near the plant. The water will evaporate into the atmosphere and provide the needed humidity. 

Another alternative of providing humidity is getting gravel and putting it in a dish then filling it with water. Then place your potted cactus in it. You can also mist your plant with a spray bottle. 

The cold-hardy Christmas cactus

The Christmas cacti tend to bloom around Christmas hence the name. They flower during winter to produce white, red, pink or lilac flowers which are usually 3 inches long. The cold hardiness of this species is higher than for other cacti. They can’t withstand frost, but they need cold temperatures to force bloom.

How to treat a Christmas cactus exposed to cold

As much as these species bloom in winter, they also don’t love freezing temperatures. If they stay out too long, the water that’s usually stored in the tissues will freeze making them expand. This damages the stems.

Once the water thaws, the tissues will contract, but they will be left damaged. This, in turn, leads to rotting spots and dropped leaves. 

When you notice your cactus looks like this, you need to treat it and try to revive it. The first step is removing any tissues that seem rotten. Water the plant lightly and place it at temperatures of 60F or 15 °C. Monitor the plant and if it survives at least six months, you can then fertilize it using a cactus-specific fertilizer. It only requires diluted solutions.

Christmas Cacti bloom in winter, they also don’t love freezing temperatures.

The idea is, if you grow your Christmas cactus outdoors, you need to take it indoors when the temperatures are extreme to avoid doing damage control. 

To encourage the blooming and healthy growth of your plant, make sure you consider repotting. You can re-pot any time between 1 and 3 years. Sometimes, you’ll notice that your cacti roots are poking their way out of the drainage holes. This is a clear indication you need to re-pot. 

All in all, proper care should be taken to all cacti species because they are more likely to have damages in these extreme weather conditions. The above tips should help your cactus stay safe.

How can I cold protect my cactus? Cactus need to be protected from the freezing winter temperatures. If your cactus is in container plants, you can quickly bring them inside your house to protect it from the freezing temperatures outside. Alternatively, for the landscaping plants, you cover them with frost blankets or bedsheets during late afternoons. Make sure the covers don’t touch the plants. You can look for support frameworks. You can remove the coverings the next day when the temperatures rise above freezing point. 

Can cactus survive with artificial light indoors? When you decide to grow your cactus indoors, you need to consider the light aspect. Light may be insufficient, and they may not thrive. Artificial lights act as a substitute for sunlight. They grow well with no issues. Make sure you attach your grow lights to a timer so that it’s easier to control the light the cactus receives.  

Why does a cactus turn yellow? There are a few reasons why cactus turn yellow. One, they can be sunburned. If they have been living indoors and are taken under direct sunlight, they will certainly become yellow. Introduce them to direct sunlight gradually to avoid this. The other reason is that they may be infested by pests such as mites. These little animals such the cacti tissues. Lastly, it could be because of root rot. Rotting is one of the significant effects of overwatering your cactus. Avoid overwatering; you’d preferably underwater than overwater. 

Learn How To Fertilize A Cactus

Just like other plants, you need the correct fertilizer for proper growth and helping them adapt quickly. Even though these plants may be used to harsh conditions, once you take them in as a houseplant or grow them outside in your garden, they require some care and maintenance. 

When is the right time to feed cactus?

It is natural to think that your cactus doesn’t need any sort of feeding because of the environment they are used to growing. However, they have the same needs as other leafy plants.  

First, you need to know that cactus don’t need excess water or fertilizer. Knowing when to feed them is important because you don’t want to have stunted growth. Fertilizing once in a year is okay, but in case you have a schedule, you can do so two to three times a year. Preferably during spring, fall and summer. However, some cacti species grow in winter, make sure you fertilize them during that period. 

During their active growth periods, cactus require fertilizer. However, too much fertilizer will ultimately weaken the plant.  Avoid overfeeding them as this will give them the chance to stay healthy.

Is it necessary to use fertilizer?

The truth is, cactus can survive without using any fertilizer on them. However, fertilizer is just a way of boosting them by making them healthier and more colorful. Be careful with indoor cactus and preferably fertilize once a year. Once you feed them, make sure you take them out under a shade in a bright place. 

Some people don’t have enough space outside, grow lights can be an alternative, mainly when you use fertilizer. 

Grow lights are alternative artificial lighting to help make it sufficient just as natural light would. They help increase the chances of your plant’s vibrancy. 

There are three types of grow lights: fluorescent grow lights, LED grow lights, and Positioning grow lights. 

What nutrients does a cactus need?

Cacti are not heavy feeders hence need a diluted fertilizer that’s half or quarter the strength. Too much concentration may lead to root rot, which is one of the leading causes of cacti deaths. 

Root rot may not be evident in the first weeks, but as you progress, the cactus starts turning pale, you notice black spots as well. Once you notice this, the damage may be a lot worse. You need to remove the cactus from the pot to see if you can save it or not.

Succulent plants.

When removing the cactus, ensure you are protected, especially if it has spines. Get leather gloves and wrap the plant with a newspaper before pulling it out. To make the process easier, dig around the cactus to soften the soil, then you can slowly remove it. 

Once you remove it, you can now access the damage. Sometimes, it may be just some roots that have rot, and you can easily prune them and re-pot the other part of the cactus. 

Fertilizers with high nitrogen content are more likely to cause root rot. Get the right blend of fertilizers. Get one with a reasonable ratio of Nitrogen(N), Phosphorous (P) and Potassium (K); N:P:K. 

Nitrogen is mainly responsible for assisting in the growth of leaves while Phosphorous is helpful in the root growth and fruit and flower development. Potassium improves the overall functionality of the plant.

Ideal Fertilizer Blends

Keep in mind that a fertilizer that’s high in nitrogen promotes plant growth while one with a higher potassium ratio is suitable for flowering. Lastly, one with a high phosphorous ratio will be better for disease resistance.   

Different ratio formulas can work. You can use equal blends of 10-10-10, 10% nitrogen, 10% phosphorous, 10% potassium.  A low balanced soluble houseplant fertilizer does the trick for the plant. Also, the ratio of 5-10-5 is ideal. 

If you are using the ratio of 5-10-5, if the instructions say you use 1 tablespoon of the fertilizer with 1 gallon of water, when using it on cactus, use ½ the tablespoon. In case your cacti species is a tropical type one like the Christmas Cactus, use ¼ of the tablespoon. 

Another alternative is getting a specified cactus fertilizer blend. These ones usually have a ratio of 1-7-6 or 2-7-7. They will generally instruct you on how to use the fertilizer on your cactus. Water your plant with the fertilizer solution just the same way you do when watering them. Let the excess one drain out of the soil to avoid the plant sitting on the solution and risking root rot. 

Dry fertilizers available

Instead of making a solution of fertilizer and water, there are dry fertilizers available on the market. We have granular slow-release fertilizers. For these, you need to mix them with the potting mix or the topsoil. However, be on the lookout as sprinkling them on top of the soil can make them not sip down to the roots when you water them. 

Types of slow-release fertilizers:

1. Synthetic Organic Slow-Release Fertilizers (nitrogen-based)

When shopping for fertilizer, you may have seen some labeled  Methylene Urea or Urea Formaldehyde. These ones are the synthetic ones, and they are usually composed of 70% WIN( Water Insoluble Nitrogen)

The rate at which these fertilizers release nutrients depends majorly on the bacterial activity. These particular ones can provide nutrition for a couple of weeks others extending to months. 

There are also other known as IBDU/isobutylidene-diurea that is 90% WIN. The rate at which nutrients are released from this product depends on pH levels and soil moisture. 

What determines the rate at which nutrients are released from these fertilizers is the size of particles. In case the fertilizer has small particles, nutrients are released faster. 

2. Natural Organic 

We have natural organic fertilizers as well, which makes them a popular choice for most people. Different types of organic fertilizers release nutrients at different rates. What affects these speeds is temperature, bacteria, and fungi in the soil. 

Some examples of these organic ones are:

  • Manure
  • Compost
  • Fish emulsion
  • Soybean meal
  • Cottonseed meal
  • Blood meal

Considering indoor cactus when using fertilizer

Since indoor cactus may not receive enough sunlight when growing, fertilize them sparingly as they may become weak. Also, in case you use containers that have no drainage holes, use these fertilizers sparingly because they don’t drain water. 

Cacti planted outside on the ground may need as much fertilizer because they quickly get nutrients from the soil. Only use half/quarter the slow-release fertilizers during the active growing seasons. 

Using manure teas as an alternative fertilizer

Manure tea is similar to compost tea and is an organic alternative to the chemical-based fertilizers. It is made from collecting manure from any livestock. Manure tea is quite easy to make.

Using manure teas as an alternative fertilizer

Steps to making manure tea

  • Fill a bucket (5 gallons/18.9l) with water 
  • Shovel your manure into a sack (use the ratio of 5 parts water to 1 part manure)
  • After putting manure into the sack, tie a knot
  • Then place the tied sack into the water in the bucket
  • Make sure to cover the bucket with a lid due to the bad smell attracting flies
  • Leave the mixture for a few days so that it forms a golden brown color
  • Slowly remove the sack in the bucket and allow the solution to drip into the bucket until it doesn’t anymore
  • For the solution strained from the sack, dilute it with clean water 
  • Once you dilute it, you can pour in the manure tea into the cactus soil for fertilizing

When using the manure tea, you can use a spray bottle or simply pour it until it drains away through the drainage holes

What makes manure tea a great organic fertilizer is a fact that it’s sustainable and mild such that there are no chances of burning the cactus. Also, the tea dissolves quickly in water, and it’s quite easy to use a spray can. 

The manure that was left after straining the tea can be used in the garden too. 

Benefits of using manure tea

1. It is natural

Manure tea contains no synthetic or chemical additives; it is natural. What’s even exciting is you can use cow, goat, horse manure, among others. 

2. Less expensive

If you own any livestock or know somebody who does, then it can be inexpensive and a great option other than purchasing the ones available. The process itself is also quick, with easy steps to follow.

Manure tea is rich in nitrogen and is perfect for the growth of your cactus.

3. Doesn’t burn the plant and is friendly to the soil

Some other fertilizers can easily destroy the soil and burn your cactus. However, for the manure tea, it doesn’t kill beneficial fungi, but it conditions the soil so that the plant can absorb the much-needed nutrients.

4. Quick to provide nutrients

Unlike other chemical products that are slow-release and may take up to months for the fertilizer to take effect on the plant, the tea is quite the opposite. It provides the plant quickly with essential nutrients for better growth. 

5. No measuring

Sometimes, it can be a bit tedious to keep measuring the ratio of water to the fertilizer and making sure you don’t put too much fertilizer that risks burning your cactus. Manure tea does not need measuring, you just need to pour it to the soil, and you are good to go. It is a total time saver.  

However, it is easy to overwater your plant, which is a leading cause of root rot. Use the manure tea sparingly and ensure the soil dries first before using it again on your plant. 

Manure tea is rich in nitrogen and is perfect for the growth of your cactus. However, you might want to back off when the cactus wants to flower (if you have a species that blooms.) 

Some of the best manures  to make your tea from are:

  • Cow manure (the best)
  • Horse manure
  • Goat manure
  • Chicken litter 
  • Turkey litter
  • Pig/cat/dog manure

Out of all the above, chicken litter has the highest nitrogen composition. Use it sparingly as it can burn the plants. Before using it, make sure it is well-aged. The same applies to all manures when you are making them. Make sure they have composted in the sun long enough (a week or so) for better results.

Out of all the above, chicken litter has the highest nitrogen composition.

As much as it’s easy to make manure tea bags, some people don’t have access to the resources. Therefore, you can purchase readily available manure tea bags sold and are a great alternative to chemical fertilizers. Be sure to use nose plugs as it doesn’t exactly have a great smell. 

Storing Manure Tea

Manure tea can be stored for between four to six days in a sealed container that is light-proof. However, if you need to store it for a longer time, you need to provide aeration with an aquarium pump or bubbler stone.

Be on the lookout to avoid storing it for a long time because the longer it stays, the higher the chances of losing its nutrient value. 

Organic vs. Inorganic Fertilizers

Before settling for a particular fertilizer, you need to know the different types available. The broadest categories are organic and inorganic. 

Both types are used to provide nutrients to the cactus. Organic (natural) fertilizers work gradually to provide a healthy environment for the growth of your plant. They contain plant and animal-based products as their work is to provide nitrogen, phosphorus, and potassium. The reason they work slowly is that the first work on enriching the soil instead of quick action. 

On the other side, inorganic fertilizers provide more rapid/quick nutrition for them as they feed the cactus with high concentrations of nitrogen, phosphorus, and potassium directly to your cactus. 

What determines what you use is your cacti needs, the environmental impact, and the costs. Note, inorganic fertilizers may leave product buildup on your cacti over time, and they don’t enrich the soil. 

I. Organic fertilizers

"organic" leaves

Organic fertilizers consist of only animal or plant-based materials that are usually end-products or by-products of processes that are naturally occurring. Such examples can be manure, compost, or leaves. 

These types of fertilizers only produce nutrients when the soil is moist or warm. Nutrients are often released quite slowly because they mainly rely on soil organisms in breaking down the organic matter. 

When it comes to using them, there are no exact rates of nutrients they contain. This makes it hard for you to know if the particular fertilizer meets your plant’s needs. However, cactus have a low requirement, which makes them perfect. 

Natural fertilizers are initially expensive, but since they enrich the soil over a long period even when the plants take the nutrients they need, they become worthwhile. 

When you look at the environmental impact, these fertilizers may cause a buildup of some nutrients. However, this buildup is not toxic. 

Since organic fertilizers are from natural sources, the greenhouse gas that’s emitted into the air is low. 

II. Inorganic fertilizers

They are commonly referred to as synthetic fertilizers meaning they are not natural. This means they are manufactured artificially and they contain synthetic chemicals/minerals. Fertilizers that are high in the three main macronutrients will almost certainly contain products such as magnesium sulfate, ammonium sulfate, ammonium nitrate, and triple superphosphate. 

Inorganic fertilizers are ‘quick-release’ types meaning they are plant-ready. They should be used sparingly, especially on your cactus, because of the chances of the quick-release increase of burning them. 

The application process is usually straightforward because there are instructions on how to use them. You can specifically get fertilizers that are designed for your cactus.  You will commonly see them written 12-6-4 which meant the particular fertilizer contains 12% of nitrogen, 6% of phosphorous and 4% of potassium (N-P-K.) Sometimes, it is crucial to know the ratio of nutrients so that you can know what to use for your cactus because different plants have different needs. 

Their ease of use makes them favorable as they are available in water-soluble powders, liquid concentrates, and dry granules. Some other tabular forms or spikes are specifically designed for container or indoor plants. 

Chemical fertilizers.
Chemical imbalances are quite popular with this kind of fertilizers because they can quickly burn your plant.

These fertilizers are not costly and are quite affordable. The reason for their cheap costs is that they are usually mass-produced. The dry granular controlled-release fertilizers are cost-efficient than even the other types. The downside though is they only work on providing nutrients to the plant but do nothing to the soil over time. 

Even though the fertilizers are immediately available to your cactus, unlike the organic ones, they are susceptible to leaching.

These fertilizers can be washed away by rainwater or when watering them, especially if you have planted your cactus outside. This way, the nutrients are washed away, which could leave your plant deprived of the fertilizer. 

Chemical imbalances are quite popular with this kind of fertilizers because they can quickly burn your plant, which causes a buildup of toxic salt that concentrates on the soil. It then ends up destroying your once vibrant plant. 

Applying fertilizer on your cactus

Using the correct fertilizer is what determines the growth of your cactus. Here’s an example of how to use your fertilizer.

What you’ll need:

  • Measuring spoon
  • A watering can
  • Low nitrogen fertilizer that is soluble
  • 1-gallon container with a lid

1. To know when to fertilize your cactus, start inspecting it early spring to see if there are any growths such as the size of spines, increased stem size. Etc. If you notice new growth, you can now start the fertilization process. 

2. Assuming that you had already purchased a low nitrogen fertilizer, which is a 5-10-10 blend, use 1 tablespoon of it and dissolve it in 1 gallon of water. After mixing the solution, water your cactus until the soil becomes moist. 

Another option is using a 1-7-6 cactus blend. Take 1 tablespoon of the mixture and mix it with 1 gallon of water and pout it into the soil until it’s moist. 

3. For the 5-10-10 blend, apply every eight weeks during spring and summer for three fertilizer applications. If you choose to use the 1-7-6 blend, apply after every two weeks during the cactus growing season. 

Note: cactus don’t require fertilizer during fall and winter as they enter the dormant and semi-dormant period. 

4. In case the fertilizer you are using remains, you need to seal it in an air-tight container until the next time you use it. 

 Some cactus species such as the Christmas cactus grow and flower during winter and are dormant during summer. Therefore, you need to reverse your fertilization process during winter. Feed them during winter because that’s their active growing period.

The difference between composting and fertilizing

Composting is the use of natural decaying organic matter from the kitchen or garden and decomposing them to have rich nutrients that have the capability of fertilizing the soil. Some people refer to this as “black gold” because it is fertile soil. I

Advantages of using compost

  • They feed the entire soil which helps in the overall health of the soil
  • They help in soil aeration and help retain moisture 
  • They enrich the soil in a way that it can provide nutrients to your plants
  • Enhances healthy microbe growth within the soil
  • Helps in assisting in the resistance against diseases
  • For your outdoor garden cactus, it’s easy to control weeds.
  • The only major setback for using compost is that, if you are planning to make your own, it takes quite some time before it’s effective for use. Make months before using to allow it to decay. 
Plant on the ground.
When making the compost, make sure not to add any plant remains that contain soil-borne pathogens into the compost mixture. They may increase the chances of infestation on healthy plants

Making your own compost

Things you need:

  • A carpet or polythene
  • Fresh soil and manure
  • Garden waste
  • A coarse draining material such as twigs
  • Water (optional)

Method:

1. You need to apply about four inches of the coarse material to the bottom of the self-assembly bin.

2. In alternate layers of different materials, apply six inches of garden waste to form a sandwich.

3. You can add water when applying garden waste if the mixture is quite dry.

4. Since compost needs to heat up so that it can work effectively, make sure you add some vital mass to your mixture. To easily do this, you can sprinkle some soil or manure on top so that it brings bacteria so that it breaks down the organic matter. 

5. After you are done, cover the mixture with your piece of carpet or polythene.

6. You then leave it for about three months. Once you exhaust the months, you can then uncover the mixture and remove the compost. After allowing in some air, you can then leave it for another three months. 

7. After the extra three months, your compost turns brown and is crumbly to touch, which is then ready to use. 

Fertilizing involves using fertilizers to feed your cactus. As earlier mentioned, it’s either organic or synthetic. 

Using fertilizers is equally beneficial as it enables your cactus to grow faster, especially if you choose the fast-release ones. Fertilizing though may have a few disadvantages such as becoming high risk, especially in case they find their way to nearby water bodies. 

All in all, go with whatever option you feel works for your plants.

Composting is the use of natural decaying organic matter from the kitchen or garden.

Learning how and when to fertilize your cactus is equally essential as having a watering schedule and choosing the right potting mix. All these factors work hand in hand in providing the right environment for the proper growth of your succulents. 

Remember that; you only use fertilizers or compost when the cactus needs them. Don’t overfeed them because just like other succulents, their fertilizer needs are minimal.

Too much fertilizer burns the plants, and the effects can be as extreme such that your plant dies. Be cautious on the portioning to avoid burns and build up. 

What is the best fertilizer for a Christmas Cactus? Unlike most cacti species, the Christmas Cactus blooms during winter as opposed to summer. The best fertilizer depends on what it needs; either blooming or plant strength and nutrition. A 20-20-20 or 10-10-10 fertilizer would be ideal with nitrogen, phosphorus, and potassium having equal percentages. Get a water-soluble one for better effects. 

Cactus Care: How to Grow Healthy Cactus Indoors?

Are you looking to spruce up your indoor space? Growing cacti at your home should be among your top considerations, and here’s why:

  • Cacti have some of the most beautiful blooms and come in different shapes and sizes, offering you plenty of options. 
  • Unlike most indoor plants, these plants need minimal care. 

When growing cacti, the first thing that you have to bear in mind is that there are two varieties of indoor cactus. Each cacti variety needs its own set of care techniques to make it thrive. The two varieties are:

  • Desert cactus
  • Forest cactus

Desert cacti are characterized by spines and can survive harsh desert conditions. Examples here include the saguaro and Opuntia. 

Forest cactus is also known as jungle or tropical cactus. Unlike their desert counterparts, these cacti do not have spines and are not resilient enough to withstand hostile desert environments. 

Examples of forest cacti are thanksgiving cacti (Schlumbergera truncata), Christmas cacti ((Schlumbergera x buckleyi) and Easter cacti (Hatiora gaertneri). 

As much as these two varieties fall under cactus, they both need different conditions to survive.

How to grow healthy cactus At your home

When growing either desert or forest cactus, you’ll either have to choose between the following options:

  • Growing your cactus from a seed
  • Buying a seedling from your local cactus store
  • Propagating your cactus from a pup
  • Root division

The seed method

You can also choose to buy your cactus seeds from a store or harvest them from an existing cactus fruit. While acquiring cactus seed from an existing plant is cheaper, these might require little more work than store-bought ones. 

Store-bought seeds are already pre-packaged. If you want to acquire your own seeds from a plant, look for brightly colored-offshoots on fruits that usually bear flowers.

Ensure that the soil stays moist, but shouldn’t stand for too long as this will promote rotting.

Remove your pods from the fruit when they are still a little damp to touch. Next, slice off the top and sides of your pods carefully using a knife to expose the seeds.  

Next, scrape off the seed from the pods using the blunt side of the knife. Finally, plant the seed in a shallow container, and ensure that you plant them on top, rather than burying them. 

Ensure that your soil is high drainage, and doesn’t allow the water to stand for long. Use a plastic wrap to cover the top of your container and place your container on a window. If the sun’s too hot, only expose them for a few hours, then put them under shade for the rest of the day.

Seedling Method

There are plenty of plant stores that sell cactus seedlings. 

If you choose to go this route, avoid planting your seedling underneath the soil and instead plant it a little below the soil surface. 

Always water your seedlings from underneath. Watering your seedling from underneath requires you to place the seed flat on a tray. Next, flood the tray with water, helping your seed soak up water from the bottom.

Ensure that the soil stays moist, but shouldn’t stand for too long as this will promote rotting. The number one reason why water would stand for too long is due to poor soil choice. We’ll discuss soil how to mix your cactus soil in a bit. 

Lighting is very important for seedlings. A window sill will do, but be careful not to scorch them. Another option is to use artificial lighting.

If you plan to use artificial lighting, be careful to expose them to the light for between 8 to 14 hours.  A simple way to do this is to switch the light on when you wake up and switch them off a night before going to bed. 

During this period, look out for the following signs, as they will indicate that your seedling is in trouble

  • Black spots which indicate a fungi
  • Algae growth from overwatering
  • Thinning seedlings as a result of inadequate lighting

The Cutting Method

Propagating your cactus from a cutting is perhaps the easiest and most common way to grow cactus. All you need to do is cut off the stem of an existing plant. 

Next, place your cutting under then sun, allowing it to form a callous. Soon your cutting will start rooting, eventually growing into cactus. Be careful not to water your plant until you see roots because the cutting will rot.

Root Division

Root division is yet another easy way to grow your cactus. Ensure that you divide the root as gently as possible to limit trauma.

The best time to carry out the division is during winter. During winter, the plants are dormant; hence there is less interference with their growth.  

 Growing forest cactus indoors

Soil mix

This cactus grows well on rocks (lithophytic) and trees (epiphytic). It’s crucial to note that although the plants grow on trees, they are not parasitic. Therefore, the plants do not acquire their nutrients from the trees and only use the trees as a means of support.

In their forest or tropical habitats, these plants get their nutrients from dead leaves and branches. The leaves often fall in crevices and provide plenty of vitamins and minerals suitable for cactus survival. 

Soil with Perlite.
Your soil needs to easily drain water, to prevent waterlogging.

The soil type usually isn’t a big issue for growing most plants. However, when it comes to jungle cactus, it certainly helps to select the right soil if you want to successfully grow the plants indoors. 

If you want your forest cactus to survive indoors, ensure that your soil mimics the natural environment in which these plants thrive as much as possible.  

When choosing the soil, the first thing that you have to focus on is drainage. Your soil needs to easily drain water, to prevent waterlogging, which might make your plant rot and eventually die. 

Look for a container that is large enough for you to mix your ingredients. An example of suitable containers is a wheelbarrow. 

For consistency, use a measuring device to ensure that you get the right proportions. Use a small shovel to mix all your ingredients. 

A small gravel soil.
ensure that your soil mimics the natural environment in which these plants thrive as much as possible

To create a suitable soil mixture to grow your forest cactus, mix the following ingredients;

Potting soil

Avoid soil that has too much forest products such as wood chips or bark because they eventually rot. The products also don’t mix well with other ingredients. 

Pumice

Pumice comprises of large volcanic rocks that are light in weight.  This ingredient is excellent for drainage as it’s porous and airy and allows water to quickly pass through.  If pumice is not available in your area, substitute it with perlite, turface or aquatic plant soil as these have similar features.

Coir

Coir is a fibrous coarse material that comes from shredded coconut. Although the material is organic, it does not compose easily.

Coir is excellent for holding moisture and doesn’t compact after rewetting. Coir might need a bit of loosening before adding it to your soil. Rub it on a mesh to break it into smaller pieces. 

Peat

Peat is a great substitute for coir. Please bear in mind that most potting soils already contain peat, so ensure that you don’t put too much of it in your soil mixture. 

Orchid bark

Orchid bark serves the purpose of aerating your soil. The bark also holds moisture for your soil so that it doesn’t dry out too quickly.  

Oakleaf mold

Oakleaf mold provides nutrients for your plants, just like in the forest or jungle.

The following proportions should work well for your potted cacti;

Mix 25% or potting soil with 25% orchid bark

Next, add 25% peat

Lastly, add 5 coarse gravel, then pearlite

You can play around with the ingredients to find a mixture that works well for your plants. 

It’s crucial to note that orchid bark eventually disintegrates turns into soil. Remember that your potted plant needs only 25% of soil. When the soil starts becoming more than the other ingredients, it will interfere with drainage, and your plants might start rotting.

Therefore, repot your plant every two to three years using a fresh mixture. A good time to repot your plants is also after they bloom. After blooming, your plant will start growing again, and this will require fresh soil, full of nutrients, has aeration and great drainage.  

Watering

Generally, you should water your jungle cactus once a week. Remember that your cactus is used to a humid jungle/forest environment so regular watering is a necessity. 

Always water jungle cactus more during the summer and spring, and taper off during the winter. Twice a week should work well during the hot months and every other week during the cold months.

Water regularly but be careful not to underwater or overwater

The best indicator that your plants need more water is to check your soil’s top 2 inches. Another indicator of whether your plant needs watering is to check the stem segments. If the segments look dry and shriveled and the soil is dry too, it’s time to water your plant. 

However, if your soil isn’t dry but the stem segments look shriveled, do not water your plant yet. Watering your plant when the soil is too damp will cause your plant to start turning yellow, and eventually rot.  

Lighting

Lighting is essential for the stems, as it makes them healthy. Optimum lighting is also essential for blooming. 

Unlike desert cacti that can take in plenty of direct sunlight, too much light can damage forest cactus. These plants will do well in natural light. However, be careful when it comes to direct sunlight, and ensure they get not more than 5 hours per day. 

A good way to ensure that your plants get sufficient light is to place it in the sun during morning hours, then moving it away when it starts getting hot.

Be keen on the climate in your area to see the best lighting needs for your plant.

Generally, the sun starts getting hotter from midday. However, sometimes climate patterns change. The weather might be hot during morning hours and cold in the afternoon. Therefore, be keen on the climate in your area to see the best lighting needs for your plant.

Temperatures

During the warmer seasons like summer, these plants will do well in temperatures of between 55 to 75 degrees. In winter, temperatures of between, 55 and 60 degrees will do. 

Fertilizers

It’s paramount to use a cactus fertilizer. Start fertilizing during summer and spring, when the plants are out of their dormant phase and are growing in size and height. 

Growing desert cactus

Soil mix

It might appear that desert cactus can only grow in sandy soil, but this is not the case. Even desert cactus needs nutrient-rich soil, which also has good drainage and aeration.

Therefore, it’s paramount to mix cactus-friendly ingredients, all of which collectively create the perfect mix for cactus growth. Here, we’ll use most of the jungle ingredients mix, with a few additions like sand and gravel. Some ingredients that are suitable for a perfect cactus mix soil are;

  • Potting soil
  • Pumice
  • Pearlite
  • Peat 
  • Coir
  • Sand
  • Gravel
  • Rocks

Remember that there’s no one size fits all when mixing the ingredients. Experiment with different proportions to find one that works best for you. 

All you have to focus on when finding a good soil mix is aeration, drainage, easy re-wetting, and nutrients. To test the soil, pour some water through it to see how fast it goes through the soil.

If water sits at the top, this soil might retain too much water and harm your plant. If your soil quickly passes water, this is the ideal candidate. 

Watering

Although desert cacti are the more resilient of the two groups, they still need regular watering. Most people assume that desert cacti don’t need water because it primarily grows in the desert.

What people don’t know is that the cactus is only able to survive in deserts where it hardly rains, because of its ability to store water. In addition, cactus also has other adaptations that limit water loss such as stomata only opening at night, lengthy dormant periods and lack of true leaves.

You might need to water more during the summer because temperatures are high.

Check the soil every two weeks to assess for dryness. The top two inches should be dry before your water; otherwise, you might be overwatering. 

You might need to water more during the summer because temperatures are high. Weekly or bi-weekly watering is sufficient during the hot months. During winter, it might take longer for the soil to dry up so you might need to water once or twice a month. 

Temperature 

During the summer, spring, and autumn, this plant thrives in temperatures of between 70 and 85 degrees. During winter, the plants can withstand temperatures of between 50 to 60 degrees. 

Lighting

Desert cactus loves light. Keep this plant in an area where it can bask in the sunlight. However, you must be careful not to let the sunlight scorch your plants. 

If you live in an area where it’s impossible for your plants to get enough sunlight, try using fluorescent tubes. Ensure that your tubes are full-spectrum, to ensure that your desert cacti get lighting that is similar to that of natural sunlight.

How do you know whether your plants are getting enough lighting?

If your lighting is insufficient, the plants will start to exhibit a stretchy thin look.

Fertilizing

Look for a fertilizer that is specific for cactus. This will give the plant the right nutrients requirements, unlike general fertilizers.

It’s crucial to re-pot both desert and forest cacti when they start growing too big. Pull out your plant gently, being careful not to shake off too much soil, leaving the root ball with sufficient amounts of soil.

Mix your soil in the right proportions depending on your cactus category. Next, plant your cactus in a bigger container.  

What to do when things go wrong

As much as cactus requires little attention from you, it’s not completely self-sufficient. If your plant is starting to look unhealthy, it’s possible to revive it once you identify and fix the problem. 

Common cactus problems and how to fix them

Shriveled or limp cactus

Inadequate watering makes your plant looks shriveled while overwatering gives your plant an abnormal limp look. Depending on the weather you need to water your plants once every week (dry areas/summer) or twice a month (wet or humid climate/ or during winter). 

Overwatering can cause your plant’s roots to rot. If you want to check your roots’ health, gently pull out your plant from the soil. Healthy roots should be white, while rotting roots should be either black, brown or look mushy. 

If left unchecked the rot could spread to other parts of your plant, killing your plant. Save your plant from root rot by scrapping off the rot. To ensure that your plant does not get a re-infection, repot it with fresh soil. 

Sunscald

Too much sunlight is bad for your plant. If your potting container heats up too fast or your plant is on a window sill, this could amplify the amount of heat your plant receives, leading to burns.

The burns could encourage the growth of fungi such as Colletotrichum (Gloeosporium). 

Initially, your plant will have small spots that will later turn brownish. Later, your plant will produce pink spores that will spread to other parts of your plant, destroying it. You can avert this problem by applying a cacti fungicide. Thereafter, avoid subjecting your plants to extreme heat and sunlight.

Insect infestation

Mealybugs can infest your cacti, and often spread fast to other plants in your home within a short period. Since the bugs sap nutrients of your plant, it may have stunted growth, which can be frustrating.

A simple way to get rid of the bugs is to spray them with water from a hose.  You can also visit your local cacti seller for a mealybug insecticide.

If you plan to buy a potted plant from your local cacti shop, inspect it for bugs. Sometimes, bugs start growing in the shops, and your seller can treat your plant before you go home, or give you a bug-free one.  

In conclusion

When growing cactus, it’s paramount to create an environment that will favor your plants. Set up the right soil, lighting, and temperature right from the start, and you will have healthy plants.  If you’re a first-time plant owner, things could go wrong, but fortunately, there are a few simple things that you can do to correct the problems.

Ultimate Guide: How to Get Your Cactus to Flower?

Getting a cactus to bloom is no easy feat. It can take a lot of time, effort, and, sometimes, feeling like you want to pull your hair out because it seems like it just won’t bloom no matter what you do. Trust me, I’ve been there.

But after several attempts to get my cacti to bloom, I have finally figured it out! And now I want to help you avoid those feelings of pulling your hair out with this ultimate guide on getting your cactus to flower that tells you everything you need to know from shopping and caring for your blossoming cactus.

The Basics

It’s a well-known fact that it can be hard to get an indoor cactus to bloom. This is mostly due to the fact that the cactus isn’t in its native, ideal environment.

Cacti are meant to thrive in desert environments with intense sun and heat and with very little water, so that is naturally the conditions cacti would bloom under.

Our homes are usually not that hot or dry however, there are different things we can do to help a cactus to begin to bloom. Let’s start with the basics of cactus blooms.

What kinds of cacti bloom?

Cacti are a flowering plant, so any cactus is capable of blooming if it is mature and healthy. But a lot of things have to be in place in order for a mature cactus to bloom. The kinds of cacti are known for their ability to easily bloom:

  • Garnet or (Dwarf cacti)
  • Pincushion cactus
  • Spiny cacti
  • Christmas cactus (Zygocactus)
  • Easter cactus (Rhipsalidopsis)
  • Bolivian (Lobivia cacti)
  • Hedgehog cactus varieties
  • Notocactus

What does cactus blooms depend on?

Age, care and dormancy. As mentioned before, it can take a long time for a cactus to blooms. Sometimes, it can even take up to 30 years for a cactus to mature!

Although, even a mature cactus won’t bloom unless it gets the proper care and lives in the right environment. And, even if it has all these things, cacti experience a dormant period during the winter that will keep it from blooming.

How can I make sure my cactus has all these things?

For starters, when shopping for a cactus, buy one that is already blooming. That way, you know that it is mature and capable of blooming. Then, follow all the basic care requirements cacti have, such as light and water, and make sure to always stay vigilant and cater your care to the different seasons.

How long does it take a cactus to bloom?

As mentioned before, it can take up to 30 years for a cactus to bloom, so make sure you buy one that already has a bloom on it or that has bloomed in the past.

However, just because it has bloomed once doesn’t mean it will bloom again in a certain period of time. The time it takes a cactus to bloom depends on the level of care you give it and the quality of the environment it is in.

Cactus Care

Light

Cacti need tons of light, just as if they were still in the desert. The best place to put your cactus in your home is a south-facing window, where it will get the most direct sunlight. If you choose to put your cactus in a different location, make sure it can still get at least 6 hours of direct sunlight.

You also have the option of using an artificial grow light to help your cactus along if you don’t think it is getting enough light. An artificial grow light might also become very helpful during the winter.

While a cactus is a very low maintenance plant, it doesn’t mean you can just sit it down and forget about it. You should be checking your cactus frequently, especially after you first introduce to its new home, so you can ensure it is acclimating properly.

Your cactus will give you signs if something is not right, especially if it is getting too little or too much light. If your cactus is not getting enough light, you might notice some slight discoloration on its leaves or stems or even the cactus stretching to reach the sunlight. If this happens, just slowly move it further into the sunlight or supplement it with an artificial grow light when the sunlight disappears.

It’s also possible for your cactus to receive too much direct sunlight. Too much sunlight can cause your cactus to burn. If this happens, you will notice sunburn across the skin of the cactus as dark, rough, and maybe even calloused areas.

Too much sun can also cause a cactus to become discolored and faded. If your cactus is receiving too much sunlight, simply move it away from the window where the sunlight is less direct and less intense.

Water

Keeping an eye on your cactus is also important when it comes to water. Cacti don’t need much water at all. Being from the desert, they store water in their stems and leaves for those long, hot dry periods they are so used to in the desert.

To know when it is time to water your cactus, feel the top of the soil. If it is dry, wet the plant thoroughly. If it is still damp, you can wait a while before watering it.

Generally speaking, your cactus shouldn’t need watering more than once a week.

The main problem cactus owners run into is with water. Even if you only water your cactus once a week, or less, if your cactus does not have enough drainage, the roots will sit in water and be prone to root rot, doing permanent damage to your plant. If this begins to happen, you will notice the leaves and stems of your cactus becoming soft and limp.

Be sure to use specialty cactus potting soil instead of regular potting soil.

To avoid root rot, not only should you avoid overwatering your cactus, but you should also take certain precautions when you go to pot your cactus.

Choose a pot for your cactus that has a drainage hole and line the bottom of the pot with a layer of pebbles for the best drainage possible.

Also, be sure to use specialty cactus potting soil instead of regular potting soil because regular potting soil holds too much water. Using it could lead to root rot, as well.

Fertilizer

Since cacti are hearty plants, they don’t really require the use of fertilizer. With proper water and light, all cacti will thrive. However, if you want to give your cactus an extra boost and make sure it has valuable nutrients for blooming, giving it a dose of fertilizer wouldn’t hurt.

Choose a specialty cactus fertilizer or a regular fertilizer that is lower in nitrogen and higher in phosphorous. If you fertilize your cactus, do it doing the growing season, spring and summer. You will only need to fertilize your cactus once or twice a year.

Just remember that more fertilizer does not equal more or faster blooms. Fertilizer just ensures your cactus is getting enough of the food and nutrients it needs.

Blooming!! What Now?

Once you have gotten your cactus to bloom, the work isn’t over! Take care of a flowering cactus the way you took care of it before it began to bloom. The blooms mean you are doing something right and the cactus is thriving!

Don’t alter your care just because you see blooms. Continue to water it on your regular schedule and do not move it to a different location. A cactus that is in bloom is no different than the cactus before it bloomed.

About the Blooms

Cacti bloom by producing flowers anywhere from the leaves or areole, or along the ribs or warts of the cactus. The flowers on a cactus are just like any other flower with petals, stigmas, stamens, and all other parts of a flower. In fact, it can even be pollinated by or used for pollination by bees and other insects.

What are cactus blooms like?

Different cacti produce different kinds of blooms. Some blooms are small, others are large or brightly colored. The type of blooms you will see depends on the cactus you buy.

How long do the blooms last?

The length of the blooming time also depends on the type of cactus you buy. Some blooms will be gone within 24 hours. Others could last 1-2 weeks.

When does a cactus bloom?

Different cacti bloom at different times of the year. Some cacti bloom in the spring after resting up all winter long. Others bloom in the heat of summer after they have stored up a significant amount of water.

Different cacti bloom at different times of the year.

Some cacti, such as the holiday cacti, bloom during the holidays they are named for. And a few cacti even bloom at night.

The Dormant Period

Cacti will naturally experience a dormant period starting as early as the fall and lasting throughout the winter as they are expecting a drop in temperature and daylight hours.

During this time, their growth will slow down or even halt for the season. The dormant period is also a time where your cactus won’t bloom (unless it’s a Christmas cactus).

Your cactus will need less light and even less water during the winter. This may happen naturally in the area they are located, or you could move the plant to an area where it only gets three to four hours of sunlight a day. The soil will dry out even slower in the winter meaning that it will take longer between necessary waterings.

This only means to stay extra vigilant to ensure not to let water stand. As long as you took the necessary precautions as far as soil and drainage, and do not water the plant until the soil is completely dry, you should not run into any issues like root rot.

Just make sure to remember to slowly transition the cactus back to its regular location and watering frequency when things start to warm up in the spring.

Troubleshooting

Even after you’ve gone through all these steps, you may find that your cactus still hasn’t bloom If you find yourself asking, “why is my cactus not flowering?” then it’s time to troubleshoot.

Every cactus is different and unique, so just one change that makes one cactus bloom might not make your cactus bloom.

Try playing with the lighting it is in.

When you try to troubleshoot your cactus blooms, it’s important to try one thing at a time so you know exactly what works and what doesn’t. It may take some time, but it will be well worth it when you see those beautiful blooms!

Light

Every cactus needs plenty of light, but different kinds of cacti have different preferences. If your cactus is thriving in the light that it is in but still not blooming, try playing with the lighting it is in.

Put it in a window with even more sun or move the plant a few feet away from the window. Or, try using an artificial grow light. Try turning the pot regularly for even growth. If you find that light is not the problem, then move on to the next area.

Water

Just like light, water is essential to a happy, healthy cactus, but just a little. The first place to start when troubleshooting the watering of your cactus is to evaluate how frequent you water it. Are you watering your cactus on a schedule? Or are you waiting until the cactus tells you it is ready for water? Make sure that you test the soil before you water it.

If you water it when the soil is dry but it still isn’t blooming, try testing the soil deeper in the pot. It may still be damp deep down. To test this, stick a pencil in the side of the pot. If it comes out clean, it is completely dry and you can water it. If dirt sticks to the pencil, it is too damp so withhold from watering it until later.

Time of Year

Always keep the time of year in mind. If it is fall or winter, you are more than likely not going to see a bloom on your cactus any time soon (unless it is a Christmas cactus). Be patient and wait until the prime growing season when it starts in the spring.

You will have a better chance to see it bloom in the prime growing season than any other season, especially compared to its dormant period. Monitor it closely to see the small buds starting to pop up!

The important thing to remember when it comes to encouraging blooms on your cactus is that your cactus needs to be in tip-top shape in order to bloom.

If it is not getting the proper amounts of water and sun, you will be less likely to see it bloom. As long as your cactus is happy and thriving, it will eventually bloom. Monitor it closely to know what it needs. Also, give it plenty of time and patience!

Bottom Line

There is no special technique that gets your cactus to bloom. Just care for it properly all year round if you want to see it bloom during the prime growing season.

Since all cacti have the potential to bloom, it doesn’t matter what kind you have as long as you have seen a bloom on it before. That way, you know it’s mature enough to bloom.

With the perfect amount of sun and water, your cactus will have everything it needs to bloom when it is ready. Some other things that can help it along include fertilizer and drainage.

Play around with all the different elements of caring for a cactus to find the right formula for your particular cactus. Every cactus is different, so don’t get discouraged if something works for someone else’s cactus but not your own.

It will take a lot of experimentation and daily monitoring for you to find what works for you.

Most importantly, don’t forget, you can do it! Getting a cactus to bloom may be difficult and take a lot of time, but it is not impossible! You can do anything you set your mind to and if you want to see your cactus bloom, it will happen. When you are dedicated to providing great care for your cactus, it will happen. Just like everything else, a little time and patience are all that you need.

7 Steps for the Perfect Cactus Garden

Cactus Gardens are great to create because they require such little maintenance. Cacti can thrive in many different growing conditions, making them wonderful plants, especially for those of us who have a hard time caring for plants.

Cactus gardens, in particular, are so much fun to care for because there are many different ways to create them and care for them. Whether you want to create an indoor or outdoor cactus garden, I have created this 7-step guide to help you start your cactus garden journey as fast and easy as possible:

1. Picking Out Your Cacti

Before you start putting together your cactus garden, you need to make several decisions. The first and maybe most important decision you should make is what kind of cacti to include in your cactus garden.

The type of cacti you use depends mostly on whether you want to create your cactus garden: indoors or outdoors.

Indoors VS Outdoors

Cacti love sunlight and warm weather. Cactus gardens do great outside when you live in a hot and dry environment and have mild winter weather. If you live in a humid area with cold winters, your cactus garden would do much better if you created it indoors in a container.

There are thousands of different cacti to choose from when creating your cactus garden. Some of the best plants to include in your indoor cactus garden include:

  • Pincushion plants
  • Hens and chicks
  • Sea urchin cactus
  • Ruby ball cactus
  • Hedgehog cactus
  • Crown cactus
  • Pilosocereus pachycladus
  • Christmas cactus
  • Eastern prickly pear cactus
  • Crow’s claw cactus
  • Pipe organ cactus
  • Totem pole cactus
  • Barrel cactus

These are just a few ideas of great indoor cacti to get you started. You are not limited to only these plants! If you have considered starting your cacti as seeds, I would highly recommend against it because it actually takes cacti an extremely long time to grow from seeds.

Cactus flowers?

One thing to think about when researching which cacti you want to put in your cactus garden is whether or not you want blooming cacti. Not all cacti bloom, but there are a few that do, such as Mammillaria, Gymnocalycium, and Parodia. Knowing which, if any, of your cacti bloom is important because it could determine where you place it in your cactus garden layout or it might affect your decorations.

Variety is the key

In fact, you don’t have to have only one type of plant in your cactus garden. In fact, the best cactus gardens include a variety of cacti and other plants. If you were wondering if you could put a cactus and succulent together, the answer is yes! Cacti and succulents do extremely well when placed together in the same container. Not to mention, cacti are succulents. Even though not all succulents are cacti, call cacti are succulents because succulents are named for their ability to retain moisture.

The only thing to keep in mind when choosing different plants for your cactus garden, including mixing cacti and succulents, is to pick plants that are similar in size and care requirements (i.e. need the same amount of light and the same amount of water), especially if you are putting them in the same container.

Choosing plants with different care requirements for the same container would make it extremely hard to care for each plant individually and would eventually lead to over or under watering or other damaging issues.

2. Location, Location, Location

After you know what kind of cacti you will be putting in your cactus garden, you will need to choose a location for it. Every cactus has different care requirements and the perfect location will depend on the type of cacti you will be using, especially if you are choosing between an indoor and outdoor cactus garden.

If you are planting an outdoor cactus garden, choose a location that gets plenty of sunlight. If you are planting a cactus garden in a container indoors, you should put it in a sunny window that gets lots of direct sunlight.

Most likely, a south or east-facing window will be your best bet. In either location, your cactus garden should get at least 6 hours of direct sunlight a day.

The location of your indoor cactus garden also depends on what kind of container you choose and how you choose to display it. Creating an indoor cactus garden is full of possibilities. You could have a hanging cactus garden, one in one large container, one in many different containers, or even one in a terrarium.

You could even use a teacup or saucer as a container for your cacti! Each kind of container has different location requirements, so make sure to choose one that works best in the sunniest area of your home. For instance, do not choose to have a hanging cactus garden if there is nowhere to hang it in the sunniest window of your home.

3. A Container for Your Cacti

As previously mentioned, there are many different kinds of containers you can use to create your indoor cactus garden. If you have an outdoor cactus garden, you can skip this step as you won’t be needing a container.

When choosing a container for your indoor cactus garden, look for one that is shallow and has at least one drain hole.

Draining is very important when planting cacti, so make sure to keep that in mind while choosing a container. If the water is unable to drain off from the cactus, the cactus will be sitting in water and be more likely to experience root rot, something that could eventually kill the plant. Cactus roots are pretty shallow, so shallow containers work well to ensure that the cactus won’t sit in too much water, as well.

Different type of containers for a different type of cacti

The type of container you choose also depends on how many cacti you plan on including in your cactus garden. Make sure to choose one large enough to house all of your cacti comfortably. Cacti can be planted right up under each other, but make sure there is enough room for each one to get plenty of sunlight.

Terracotta pots are very popular for cactus gardens because of their variety of sizes and great drainage, as well as the fact that it creates a pretty aesthetic.

4. It’s All About the Soil

After you have the perfect container and all your plants, it’s almost time to plat. But first, you need the proper soil. Cacti require special soil. Regular potting soil is not good for cacti because it holds way too much water.

If you plant your cactus in regular potting soil, it will not do well and will possibly die. In fact, without proper drainage, your cacti may begin to experience root rot where the roots are sitting in too much water and rot the plant from the roots up. Root rot is fatal to cacti if it goes on too long without correction.

Making you own cactus soil allows you to control the amounts of each item you use.

Cactus soil is specially formulated for optimum drainage. You can buy cactus potting soil, or you can prepare the soil for your cactus garden yourself.

Cactus potting soil is created with a mixture of one-third regular potting soil, one-third coarse sand, and one-third pumice or perlite.

The regular potting soil serves as the base for your cactus potting soil. Coarse sand allows for drainage in soil mix and can be the sand you buy to put in a sandbox. Finally, pumice or perlite are other additives that create good drainage and retain very little moisture.

All you have to do is mix all three items together to create your own cactus potting soil. Also, to ensure the best drainage possible, line the bottom of the container of your indoor cactus garden with pebbles or gravel before adding the cactus potting soil.

Cacti require special soil

Making your own cactus potting soil can actually be much cheaper than buying a store-bought mix. It’s also a good idea because it allows you to control the amounts of each item you use.

Once you create your first batch of cactus potting soil and start using, you may find that you want to add more or less of one of the ingredients, which is totally fine! The more cacti you plant and take care of, the more you will be able to understand what ratios work best for your cacti.

To plant your cactus garden in the ground outdoors, the same principle applies: the soil should have great drainage in order for your cactus garden to thrive. While you don’t necessarily need to create a large mix of cactus potting soil, you may need to add some items to the ground soil before planting.

To know if you need to alter the ground soil, dig holes for your cacti that are less than a foot deep and fill it with water. Allow 30 minutes to pass and then check it. If water is still standing in the hole, add coarse sand and some rocks to the bottom of the hole before finally planting your cacti. If water is not standing in the hole, you should be good to go. However, if you want to add sand and rocks to the hole anyway just to be sure, it wouldn’t hurt the drainage for your cacti at all.

5. Finally Time to Plant

Once your soil is optimized for drainage and your container is filled, it’s finally time to plant your cactus garden! Before you start to put your plants in the soil, take a minute to think about how you want to layout your cactus garden.

There is no right or wrong way to layout your cactus garden. The only thing to keep in mind is to try not to plant the cacti where some get more light than others. Make sure all of them have access to the direct sunlight. That’s the only rule!

You can be creative as you want when planting your cactus garden. Create a shape with your cacti or give them a more natural layout and plant them in clusters. You could even create layers, planting some taller than others. It’s your garden, so plant them whatever way makes you most happy!

One issue you may run into when plating your cactus garden is how prickly cacti can.

When you are ready to finally place your cacti in the soil, dig small holes in the soil, just deep enough for the cacti’s roots to fit. Place all of your cacti in their holes before you pack down the soil just in case you want to change the placement of the cacti once you see what it looks like.

When you are finally happy with where all the cacti are, pat down the potting mix, give it just a little water, and you are good to go!

One issue you may run into when plating your cactus garden is how prickly cacti can be. If you are worried about your hands getting stuck, use thick gloves to avoid getting pricked. Or, you could even use kitchen tongs so you don’t have to touch the cacti with your hands at all! Even a folded newspaper will work to help you not prick your hands.

If you have trouble getting the cacti out of the containers you bought them in, you can knock on the container a couple of times to knock the roots loose, or use an old, dull knife and scrape around the edges until the cactus comes loose.

6. Decorate

Now comes perhaps the most fun part of creating a cactus garden: decorating! Just like with the layout of your cactus garden, there are endless possibilities for decorating it and it is all up to you and your preferences!

There are lots of different things you can use to decorate your cactus garden like colored pebbles, small stones, large rocks, figurines, and so much more. Decorations can be as extravagant or simple as you want.

When using a cactus garden as décor, many people start with the container. When you choose a container for your cactus garden, choose one that matches the theme of the décor you are looking for. For instance, if you are going for a southwestern themed décor, terracotta pots are the way to go. Or, if you want something more modern, choose a clear glass terrarium.

The options don’t even end there! You can always hand paint and decorate whatever container you have lying around to fit your décor theme!

After your container is filled with plants in your desired shape or layout, then you can add more décor.

Decorations can be as extravagant or simple as you want

Here are some ideas to get you started:

  • Layer the soil with a single layer of pebbles colored white or red
  • If you have a clear glass container, lay down multiple layers of different colors to be seen through the side of the container
  • Create even more patterns with many different colored pebbles
  • Use large rocks or tall figurines to all more dimensions to your cactus garden.

Once your decorations are all in place, you are all done!

7. Care for Your Garden

Now that you are done creating your cactus garden, all that’s left to do is care for it!

Sunlight

As mentioned before, your cactus garden needs plenty of sunlight. Check on your cactus garden every day to ensure it is healthy and thriving. If your cacti aren’t getting enough sunlight, you will notice their leaves and stems stretching towards the sunlight. You may also notice some discoloration.

It is also possible for your cactus garden to get too much sunlight.

If you see any of these warning signs, slowly move your cactus garden into more direct sunlight until leaves or stems begin to perk up and colors become more vivid.

It is also possible for your cactus garden to get too much sunlight. If this happens, your cacti will lose its green color and potentially become sunburnt with rough and calloused skin.

To correct this, simply move your cactus garden out of the sunlight into an area with lower light. When moving your cactus garden, always keep an eye on it after its move to make sure it’s still getting enough sunlight.

Water

Another major component of caring for your cactus is water. Cacti don’t need a lot of water. In fact, to know when to water your cacti, feel the soil. If it is dry to the touch, go ahead and water it thoroughly. If the soil is wet, your cacti don’t need any water.

You can tell if your cacti are not getting enough water if its skin or leaves are puckered or shriveled. If your cacti are getting too much water, your cacti will feel mushy and potentially begin to experience root rot.

If any damage happens to your cactus garden, it does not mean it is dying. There is always a chance to correct it. Any damage done to leaves due to too much sun, too little sun, too much water, or too little water is permanent. However, you can always prune the damaged leaves or stems away.

Fertilize

You may decide that you want to fertilize your cactus garden at some point. Cacti are hearty plants that can thrive in almost any condition, so you don’t necessarily need to fertilize it.

However, give your cactus garden a dose of fertilizer that can give it an extra boost to thrive no matter the season or growing conditions.

If you choose to fertilize your cactus garden, most any fertilizer that you use for house plants would work for cacti. You may also use a fertilizer specific for cacti, like Miracle Grow Cactus Fertilizer.

Look for a fertilizer higher in phosphorus than nitrogen. You can fertilize cacti as little as once a year. Or, you can fertilize it 2-3 times a year if you can keep up with a fertilizing schedule.

Bottom Line

And that’s it! As I said, cacti are easy plants to take care of. They require very little maintenance and as long as you give it the proper setup, they will thrive for a very long time. If you follow this 7 step guide for creating your own cactus garden, you will have a thriving garden up and running in no time!

Cactus Care: 11 Essential Tips For Beginners

I have always loved cacti and how easy they are to manage. They are your ideal room-mate as they are easy to grow with less attention. The most exciting part is when they bloom! Depending on what type your cactus is, they may have red, pink, blue, yellow, or white flowers.

As a beginner, it’s important to note that you need to know how to care for your cacti. If you overwater them, they may end up rotting. Keeping them in the right conditions will see them thrive and live for decades.

We have compiled a beginner’s guide on caring for cactus, here are 11 easy to do tips: 

1. Start with a bang – the potting mix is everything

The truth is, different cacti species live in different conditions. There are those that prosper in dry sandy soils while others do well in tropical rainforests. When you decide to purchase your cacti, ensure you know its species and what type of conditions make it thrive. 

After buying it, you need to get a potting mix that is appropriate for it. If you get a potting mix designed for tropical cacti but use it for the arid plant, it will not thrive. 

The ideal tropical cactus soil

Epiphyllums are a species of cacti found in the tropical rainforests. If you decide to go with such species, ensure the potting mix is ideal for it. Tropical cacti will drain quickly as they are usually suspended in trees so that their roots don’t rot due to too much water. 

For such a cactus to thrive, it needs soil that drains well. For tropical cacti, they need a little bit more organic matter in the potting mix than the arid cacti.  

The arid cactus soil

Most of the cacti that grow in arid areas, if they grow in poorly draining soils, they will eventually not grow. Most of these cacti will thrive in purchased potting mixes specifically for cacti.

A few steps to making the best cactus soil

There are available potting mixes in the market that are ready for use. You can purchase such and skip all the processes of making your own potting mix. However, making your own mix helps you have the right nutrients for your young cacti. 

To make the potting mix, follow the following steps:

  • Use equal portions of ground fir bark and peat moss in a bucket for either arid or tropical cacti.  
  • For a tropical cactus, use the mix above to add builder’s sand because they require more moisture. You can also use vermiculite or pumice instead of the sand for the desert cactus.
  • Ensure you mix everything to make sure the mixture blends evenly.
  • You need to water the mixture before transferring it to the pots where your cacti will grow. Leave it to absorb for an hour such that even when you squeeze the mixture, no water droplets form. 
  • Don’t add any fertilizer at this point because cacti have minimal nutrient requirements.

2. When should you water your cacti? 

Even as some of the cacti are usually in arid areas, they require water. Therefore, even when you purchase a cactus that’s designed for such areas, you need to have a watering schedule. 

Cacti are naturally juicy, which means they store moisture. One of their adaptations is that they store water so they can use it during the dry seasons. They can stay for quite some time without water, but most often you’ll tell when it is insufficient as they start yellowing.

A water gauge can help in determining the soils moisture — only water when the topsoil is dry.

Most cacti experience growth during the warmer seasons. During this time, you need to water them adequately. In cold seasons, winter and spring, they require less moisture. 

Watering depends on where your cactus is placed. If it is outside in direct sunlight, you may need to water regularly as compared to when it’s indoors. 

On average, during spring/summer, you can water once a week or even more, depending on whether the soil dries or not. 

A water gauge can help in determining the soils moisture — only water when the topsoil is dry. Overwatering cacti will make its roots rot, and the plant will start turning pale. Another alternative would be using a stick to poke the soil to see if the bottom has water. If soil sticks on the stick, then there’s still water. 

There is also a downside to underwatering. The cactus turns pale, and it bends in a particular direction. 

The idea with watering cactus is ensuring you strike a balance and avoid under or overwatering.

Tips to guide you through watering cactus

  • The cactus size

You’d think that a bigger cactus in size will need more watering, but in the real sense, the smaller, younger ones have a higher growth rate, which means they need more water. The smaller ones will need frequent watering than large ones. 

  • Pot size also affects how frequent you water

Small pots are necessarily ideal when watering because cacti don’t love sitting in water as they are more likely to rot.

Make sure to use a pot that removes the excess water thoroughly.

Large pots will take time for water to drain, which make the cactus susceptible to not thriving. 

Get a pot that’s just enough for your cactus. 

  • The type of pot you use

Even as we consider the kind of pot that’s ideal for growing cactus, what matters the most is if the soil is aerated. 

Plastic pots can be used but take time to dry out as compared to terra cotta pots. They ensure there is maximum air movement and drain excess water faster, reducing chances of the roots rotting. Make sure to use a pot that removes the excess water thoroughly.

3. Is using a fertilizer necessary?

A plant needs nutrients to thrive. For proper care, you need to purchase a fertilizer designed for cacti. They need additional nutrients for them to grow well. For most cacti, their growing season is usually the warmer months. 

When looking for fertilizer, ensure you get a low-nitrogen one but high in phosphorus. This helps in maintaining the healthy looks of the cactus.

Always ensure you inspect your cacti during spring to monitor any new growth. Only apply fertilizer when you notice the growth. 

The fertilizer should be in the ratio of 1 tablespoon of the low-nitrogen fertilizer with 1 gallon of water. Use this solution to water the cactus. Use this every eight weeks during spring/summer. 

Safety tip:

If you recently potted or repotted the cactus, don’t use fertilizer until the plant establishes itself in the new pot. This can take up to two months. 

Some cacti such as the Christmas cacti bloom in winter and remain dormant during summer. In this case, fertilize them in winter. 

4. Give your cactus the sunlight they need

Light is a necessity when caring for cactus. Desert cacti love direct sunlight and would do with four hours a day of some direct sunlight. The tropical cacti such as Christmas cacti prefer partial shade. During winter, tropical cacti such as Rhipsalis would ideally need direct sunlight because that’s when they bloom. If possible, expose them to direct sunlight for their growth. 

Get to know your cacti well and know what works for them. 

For indoor cacti, to get adequate light, ensure they are 4 feet of the window if it faces the east or south. Keep rotating the plant because too much sunlight will make them turn yellow or white. 

During winter and autumn, cacti will need temperatures of between 8-10°C. In summer and spring, even as they require proper ventilation, they can do with higher temperatures.

If you are growing your cactus indoors, it is important to rotate it preferably every month. This is because cacti will tend to grow towards the light. Rotation strikes a balanced growth. Rotate the pot a quarter turn.

Can using grow lights work?

In the case that you think you won’t be able to provide sufficient sunlight, you can buy grow lights. 

Grow lights are artificial lamps designed to help with indoor plants that require light but is insufficient in the growth of plants. 

A Russian botanist first discovered them. 

We have three types of grow lights: light emitting diodes (LED), fluorescent lights, and high-pressure sodium (HPS) or high-intensity discharge (HID). 

  1. Fluorescent lights are used to grow herbs and vegetables indoors. 
  2. For the HPS, you need to place your cactus a distance away from them as they produce quite high amounts of heat. They also require you to invest heavily in setting them up and having a system that will manage the temperature. 
  3. The LED is more efficient than the other two types, and the light is far more focused. There is also very minimal heat produced if any. 

A grow light will be able to imitate sunlight, which will help the cactus during their growing stage and help them to bloom. 

5. Be on the lookout for pests as they are a major concern

In most cases, the most common cacti problems are bacterial and fungal diseases caused by overwatering. However, once in a while, pests such as mealybugs will attack them. Controlling these pests may be difficult because they may keep recurring or become stubborn and end up damaging the cacti. 

Mealybugs and scale

These two insects are the most common insects that manage to get past the cactus spines and can do a lot of damage that may end up killing the cactus. 

Mealybugs are usually in clusters and have a white, waxy and cotton appearance. They are not easy to spot because they stay in hidden parts of the cactus. They are mostly found on the underside of the leaves and hidden joint areas. 

They mostly attack the leaves and stems. There are those that attack the roots and will usually suck the root juices causing the cactus rot due to bacterial infections. 

Scale insects are dome-shaped, and just like mealybugs, they also attack the leaves and stems. 

Spider mites

To know if spider mites have attacked your cactus, the first indication is usually webbing and some small brown dots on the plant. They are quite small and only noticeable when you tap the affected area with a piece of paper because they resemble dust. 

Fungus Gnats

These particular pests resemble mosquitoes. They mostly hover around the soil. The larva lives in the soil, which ends up consuming the organic matter, which deprives the cactus its nutrients. If you were just starting and you had planted cactus seedlings, they may end up not growing.

Pests can be a major concern

How do we manage these pests? 

In as much as cacti don’t need much care like some other plants, it’s essential to ensure you observe them keenly for any pests. They may be the reason your cactus is not growing. 

  • Practice measures to prevent pests

How you nurture your cactus also contributes to its health. Ensure your plant gets the right amount of water, sunlight, and drainage. When it thrives, it has a lower risk of pest attacks. Keep the cactus pots free from any dead leaves as they may end up attracting pests. 

  • Control the new cacti plants

Sometimes, you may end up having an old infected cactus, ensure that it is not near the new cacti as you risk the pests transferring to it. Quarantine them until you confirm they don’t have any pests. You can even choose to discard the old infected cactus. 

  • Use cotton swabs to deal with mealybugs

If your cactus is already infested, use cotton swabs that are dipped in alcohol to remove mealybugs and scale insects. 

Spraying the plant with an alcohol solution diluted in water may ruin the plant’s epidermis. You can test the solution on a small area before spraying the whole area. The solution will help you get rid of unnoticeable pests as well. 

  • Washing off spider mites

Wash away the spider mites with water. Make sure you cover the pot to avoid overwatering. 

  • Using insecticidal soap 

Insecticidal soap can be used to wash off the pests. However, note that it can damage the plant as cacti have wax that could be damaged by the soap. Make sure you read the label to ensure that it’s safe for use on the cactus. 

  • Safe insecticides

Insecticides are also an option but should be used sparingly. Always read the product’s label before applying to see if it’s safe to use on your plant.

Some insecticides are oil-based, meaning oil remains on the plant, and exposure to sunlight could make the cactus have a tan. Limit the sunlight by placing the cactus in a dull place until the pesticide works then you can return it to its usual place. 

6. Observation is key

You know how delicate babies are and you have to keep checking what works for them and what doesn’t? The same applies to cactus. Keen observation in their growth helps you know what works for them. How they grow will tell you what they are lacking. 

For example, when you see the leaves growing towards sunlight, it is a clear indication that they are not getting enough. Change their location and get a place that has better lighting or consider investing in grow lights. 

If the cactus seems faded, it means it is getting too much light. Move it to a place with less light. 

7. Profile your plants

As a beginner, you probably don’t know much about cactus. When you decide to purchase one, you need to know the basics. Like what species is it? Where was it picked from? What were the living conditions?

The idea here is to ensure you have a little background about your plant so that you can mimic its old living conditions. Ask the person in charge during the sale to give you their contacts in case you need advice on how to nurture the young plant. Some stores will provide you with an overall guide on what you should and should not do.

It’s incredible how much information you can get online.

When purchasing the cactus, inspect it to ensure that it looks healthy. Remember that an old cactus will have a bit of scarring which should not worry you. However, if the plant seems discolored, don’t buy it. 

Once you know a bit of the cactus, research more on success stories. The internet should be your best friend here. It’s incredible how much information you can get online. After you have all the information, get started with growing it and trying to follow what you know.

With time, you get accustomed to the cactus. Every plant is unique, along the way you will learn how to treat it to get it growing and even blooming. The biggest advantage of cacti is that they live for decades some going even up to 200 years. 

For example, for the Christmas Cactus which is commonly grown indoors, the best time to propagate is late spring because that’s when they grow. Some cactus never bloom at all. However, to trigger the Christmas Cactus, the nights need to be 14 hours and days 8-10 hours for about six weeks. You may need to cover your cacti at night if there’s light. 

Know when you need to fertilize your cactus and when to water it. 

8. Joining groups of people who care for cactus

Sometimes, doing this alone is not as effective as when you have a group of people helping you. Find people who grow cacti and get to learn from them. It can be as simple as getting our Facebook group or checking your neighborhood for people who have similar interests. 

Take the chance to ask as many questions as possible for people to help. You may be surprised to find that you are also helping them because there must be some things that will work for you and feel the need to share. 

9. Repotting should be at the top of your mind 

When you start noticing roots finding their way out of their pot, it’s time to report. Since cacti are not very demanding, you may think that they don’t need repotting, but the truth is, you need to take care of them for them to have proper growth. 

It’s advisable to repot every 2-4 years. If you fertilize, do so after every four years but if you don’t, repotting every two years is ideal.

Repotting can be a great way to reviving your cactus

Follow these steps when repotting:

  • Get the necessary tools 

Before you begin the process, have a unique potting mix in a pot that’s a size up the previous one. Since most cacti are spiky, you could wrap the plant in layers of newspaper and secure with tape. Alternatively, get leather gloves to avoid the cactus pricking you.

You will also need a good pot (clay ones are perfect) that quickly drains any excess water. 

  • Loosening the soil

Using a blunt/dull knife, loosen the soil until you are able to remove the cactus. Be careful not to damage the plant. Using your leather gloves or the wrapped newspapers around the cactus, gently pull it out. Pulling the cactus out with barbecue tongs can also work. 

Put into consideration that different species have different sizes of spines. For example, the Prickly Pear has tiny unnoticeable spines that break easily and can easily stay lodged in your skin. Therefore, ensure you have gloves that will shield you from any spines. 

  • Cleaning and inspecting the roots

After you’ve pulled the cactus out, brush off any lumps of soil on the roots. It’s important to you check the roots for any rot, or pests. 

If you notice any pests, use insecticides that are safe for the cactus. Check the label for instructions.

If there are any dead roots, cut them off as well. 

  • Drying the roots

Letting the roots dry is an essential step before transferring the plant to a new pot. Leave them for about three days. 

When removing the cactus from its previous pot may have damaged some roots and if you transfer it immediately at its state may prevent it from thriving. Letting it reduces the chances of infection. 

  • Use an appropriate pot

Once your roots are dry, the next step is transferring it to the next pot. Always choose a container that’s just slightly bigger than the previous one to allow growth. The danger of using a large pot is water retention is high, which increases the chances of root rot. 

Species such as Ariocarpus and Aztekium are more susceptible to rotting. 

  • Adding soil to the pot

Before adding soil to the pot, add some gravel or crocks for easy drainage when watering the plant. Purchase a potting mix or make your own enough to keep the cactus planted. Try to avoid putting excess or less soil. 

  • The planting process

After you’ve added soil, use the barbecue tongs or newspaper you had when pulling the cactus out to place it at the center of the new pot. Place it gently on the soil in the soil and don’t forcefully place it as this could cause damage to the roots. 

Pour in more soil to hold the plant. Ensure it entirely covers the roots. Add some compost to help maintain the soil’s acidity. 

  • Allowing the plant some recovery time

Most importantly, once you’ve repotted, don’t add water immediately. Wait for some days before you water the cactus so that it dries and recovers. 

If you have a particular species that rots quickly, wait for a week or two before watering. After that, you can smoothly go back to your routine of caring for your cactus. 

 Tip:

Repot during summer because it is easy for the roots to break or rot during winter. 

10. Proper air circulation for the growth of your cactus

Let’s face it; cacti hate stiff breezes. They grow well in places where there is sufficient fresh air. If you grow your cactus indoors, then make sure the conditions are right to do so.

 Open your vents and windows during summer and incorporate ceiling fans for better air circulation. 

11. Put your potted plant outside sometimes

For you to keep your cactus at its peak, if you strictly do indoor growing, place them outside during summer. Make sure they get the light they need to avoid edema. Select a sheltered spot. During the rainy season, ensure they don’t soak in rainwater and be on the lookout for snails as they may end up destroying the juicy stems.

Bottom line:

The idea of having cactus on your patio or indoors is exciting. As a beginner, you don’t have things already figured out. However, the above tips should help you get started on how to care for cacti. 

Cactus is great indoors because you can use it as part of the decor. Some cute white pots with a Christmas Cactus makes the house look alive. Whether you want it in your bedroom or the kitchen, it is a great addition. With the findings above, you can be sure that your cactus will grow healthy. 

Why Is My Cactus Turning Yellow?

You finally got a cactus plant, and it’s been sitting pretty in your house. You can’t wait for the beautiful flowers to start blooming! The lady at the nursery mentioned a few things you should do to prevent your plants from turning yellow, and as usual, you forgot some…We are here to help you with that.

What might make a cactus plant turn yellow? A few things might lead your cactus plant to turn yellow, such as insufficient lighting, insect infestation, excess watering, or even lack of proper nutrients. The wrong kind of soil can also affect your plant’s color or survival.

Read on to see more in-depth info on the topic. Information is power, and it can help you learn how to take care of your cactus plants best.

6 Reasons Why your cactus is turning yellow

The cactus is a striking plant and can give your home a fresh new contemporary look. The succulent comes in many different shapes and sizes, and the beautiful flowers it sires also come in various vivid and gorgeous hues. 

Besides its unusual beauty, the plant is easy to care for, and can even take some neglect. Unlike most plants that require constant care, this plant requires minimal effort. 

As much as it’s easy to take care of this plant, it might sometimes end up not surviving, under some conditions. The hue might also start changing from green to a yellow color. 

Nothing is as disheartening as watching your cactus turn yellow right in front your eyes. The first thing you might ask yourself is what could have caused the change — usually, it’s the conditions around the plant that are the source of the problem. 

Worry not, these are just simple oversights. There are a few things that are easy to adjust, and will not take a lot of your time. All you need to do is start making small adjustments here, and your plant will thrive. 

1. Inadequate light

A cactus exposed to sunlight.
Too much or too low can affect your cactus

There’s such a thing as too much or too little light when it comes to the cactus plant. The amount of light that your plant will need will depend on the species. 

You might be tempted to put your succulent on the windowsill, but this might result in sunburns, which can turn the plant yellow.  Remember, not all species require too much light. 

The only way to find out if your plant is getting adequate light to observe its behavior. If the plant’s color is turning from green to yellow, this indicates too much light. 

If the plant is indoors and starts to grow towards a source of light such as a window, this indicates that it’s not getting the amount of light it needs to grow. 

Move the plant to a location that has natural light such as a window. Make sure to turn the plant regularly to ensure that all the parts get sufficient lighting.

If the weather conditions keep changing rapidly, your plant may scorch, and this might harm it for life. If the sun becomes scorching and your plant is on the window, move the plant away for a few hours, then return it when temperatures regulate to normal.  

If your plant is outdoor, place it in a sunny place in the morning, and then under a shade in the afternoons. The afternoon sun is hot and may end up discoloring the plant. 

Some experts recommend putting your plants in the most South or Western window in your house. 

2. Soil type

According to SFGate, cacti need properly draining soils. Heavy soil types such as clay soil might end up retaining too much water, which may make that plant’s roots rot. 

Once the roots start rotting, the plant will be unable to transport nutrients from the soil, making the plant turn yellow. 

Ensure that your container isn’t too big, as bigger containers tend to make the soil stay wet for too long. If your soil’s drainage is not good, try adding a little bit of sand to solve the problem.

3. Underwatering or overwatering

Lack of sufficient water can harm your cactus

It might seem like it’s okay to let the cactus go without water for months since it’s a desert plant, but lack of sufficient water can harm your cactus. 

Watering is an essential part of every plant. Even cactus in the desert does everything in its power to collect and conserve water because water is necessary for the plant’s growth.

However, too much or too little could harm your plant. The cactus plant swells when it has sufficient water. 

During summer and spring, when the plant is in the growing season, it may start using up more water from its reserves, and this may cause it to look shriveled. The plant may also turn yellow, and this is usually visible from the parts closest to the soil going upwards.

Although cactus can store plenty of water, too much might be detrimental to its health. Too much water makes it impossible for air to travel to the roots, turning it yellow. 

With little or no aeration in the soil, fungi and bacteria are also likely to grow, which might eventually kill your plant. 

Another sign that you’re overwatering your plant is the darkening of leaves. The plant might also start rot. 

How do you know whether you’re providing the right amount of water for your cactus?

  • Using your fingers

Insert your finger into your soil to test soil dryness. Ensure that the top one or two inches of soil in your pot is dry. This indicates that the plant needs watering.

  • Use a moisture meter

You can also use an electronic moisture meter to help you establish whether your soil has enough moisture. The gadget is inexpensive, and you can get it from your local plant store.

All you need to do is push the gadget into the soil. If the marker is dry, it shows that the soil is dry enough for watering. Otherwise, refrain from watering your plant unless it is necessary. 

  • Use a wooden or bamboo stick

Insert a wooden stick into your pot. Remove the stick, and on touching, it should feel dry. If it feels wet, do not water your plants, as you will be overwatering them. 

Generally, water your plants bi-weekly. Ensure that your pot has some perforations. When watering, ensure that at least some water starts leaking from the holes, and this is when you can tell that your plant has had enough. 

4. Wrong temperature

Desert climate is sweltering during the day and freezing at night time. For some plants like the Christmas cactus epiphyllum and jade, the cold weather at night is essential for blooming. Therefore don’t worry too much during cold weather. 

During summer, the soil might dry out too fast, leaving your plant without adequate water. If your plants are outdoors during the hot season, you might need to water them weekly, instead of doing it once every two weeks, otherwise, they’ll turn yellow.

The temperature in your house is humid from cooking and breathing. Unlike in the desert where there’s free movement of air, the temperature stays humid because you close your windows and doors at night. Your soil ends up absorbing this humidity, and this might encourage the yellowing of your plant, as well as root rot. 

5. Bug infestation

Insects might love your cactus too

Some bugs like scale insects, mealy bugs, spider mites, slugs or snails attach themselves to cactus as they suck on the succulent plant juices. When these critters detach from the plants, they leave marks.

The insects also spread fast, and tend to attack plants in colonies. When this happens, the plant may look discolored. The best way to remove these bugs is to use an insecticide that you can get from your local pest control store. 

6. Lack of proper nutrients

Cacti need nutrients to thrive. A reason why your plant could be turning yellow is due to improper nutrient absorption by the roots. This problem is common where the roots are rotting.

Inspect your roots to see if there are any signs of rotting. If the roots have started to rot, you may need to regrow them. Scrap off the rotten parts, change the soil in the pot, and replant your roots.

Why does my cactus look shriveled? The cactus soaks up a lot of water, and when it has sufficient water in its storage, it looks plump and turgid. When the water starts drying up, especially during the dry seasons or due to inadequate watering, it starts losing water, which makes the plant look shriveled. When this happens, water your plant, and it will begin to regain its health once again. 

Why is my cactus turning brown? Your cactus might be turning brown because of a mite infestation. Mites are spider-like insects that attach themselves to the upper parts of the plants, to suck juices. This type of infestation is more common in indoor cactus than in outdoor cactus. It’s essential to thoroughly inspect your plant if you’re purchasing it from a nursery, as it might already have mites.

Can A Cactus Grow In Shade?

Lots of people buy cacti because they think it will be a great plant to freshen up their home that requires little to no maintenance. However, after several attempts to keep a cactus living, I have realized that cacti still require care and, more importantly, the proper placement.

Can cactus grow in shade? There are some cacti that thrive in low light, but most cacti need light. In fact, the best place to keep a cactus indoors is somewhere where it can get at least 4 hours of light. Cacti need to be in the sun or bright, indirect light. Windowsills facing the south or east are usually the best indoor locations for a cactus.

As a desert plant, cacti need plenty of light. However, the amount of light each cactus needs depends on its type. Doing some research on your specific type of cactus may be beneficial. In this article, we will try to help you understand how much light your cactus needs.

How Much Light Does an Indoor Cactus Need?

As a general rule of thumb, cacti do best when they can get at least four hours of sunlight a day. If your cactus is a flowering cactus, you may want to give it more sunlight during the growing season, which is usually March through September, to encourage flowering.

It is recommended that you place your cactus in windowsills facing the south or east because those directions get the most direct sunlight. If your cactus is a fresh cut or has just been transplanted into a new pot, wait one to two weeks before putting it in a location with direct sunlight so not to damage its new growth.

If there is not an area in your home where your cactus can receive this much sunlight every day, you can supplement natural light with an artificial grow light. If you choose to use an artificial grow light, leave it on for 10-14 hours a day, depending on the time a year and how much natural sunlight reaches it in the location you have chosen for it.

If your cactus is a flowering cactus, you may want to give it more sunlight during the growing season.

To find the best spot for your cactus to receive light, take note of what areas in your home receive the most sun and for how long. You may find there is a sunny location in your home that is not in the south or east after you take note of the sunlight coming into different locations at different hours of the day.

Monitoring your cactus after you have put it in one of these locations will tell you all you need to know about whether it is a good location to leave it or not. You will easily be able to tell if the cactus is receiving too little or too much light by regularly checking the condition of its stems and leaves over time.

When growing a cactus indoors, it needs:

  • 4 hours of direct sunlight a day
  • A windowsill facing south or east
  • Time to get adjusted to its new home

How Do You Know if a Cactus Needs More Light?

If your cactus is not getting enough light, it will start to stretch in the direction the light is coming from. This is known as etiolation. For instance, if a cactus is planted in the center of the pot and it begins to experience etiolation, you will notice it stretching away from the center. If this happens, try finding a spot that receives more light for your cactus. While your cactus can recover from not having enough light for a period of time, if your cactus experiences etiolation, the growth pattern it develops is permanent unless you prune it or clip it off.

You may also notice your cactus growing more on one side than the other. This just means one side of your cactus is getting more light than the other. Rotating your cactus regularly can prevent this and promotes more well-rounded growth all over the plant.

Your cactus may also experience thinning of the top growth if it is not getting enough light. If you move your cactus to a location where it receives more light, do so slowly over several days to introduce it to its new home and prevent scorching.

Other signs of your cactus not getting enough light is discoloration, fading colors, and root rot where the soil stays wet for too long. Cacti have a deep green color when they are healthy. Unhealthy cacti will fade to a pale green color.

If a cactus needs more light, signs include:

  • Etiolation
  • Thinning of top growth
  • Discoloration or fading
  • Root rot

How Do You Know if a Cactus Needs Less Light?

As you may already know, cacti love light. However, too much light or rather, too much heat from sunlight, can damage your plant.

If your cactus is getting too much light, it will start to change colors. It will look bleached, or even turn shades of yellow or orange. It may even get sunburnt. This typically happens if your cactus is in a window with too much direct sun exposure or if you introduce the cactus to more light too fast.

Sunburn on a cactus looks brown or calloused. It will also look rougher than the rest of the plant. The damage done to sunburnt cacti is permanent, but the leaves or stems that are sunburnt can be pruned and removed. If this happens to your cactus, move it to a location where it gets less light or receives more indirect sun exposure.

If you do choose to move the location of your cactus, especially if you are moving it to an area where it gets more light, allow it plenty of time to become adjusted to the new light. Do this by slowing moving your cactus closer to the light source over a period of a few weeks.

If a cactus needs less light, signs include:

Can Cactus Grow in Bathroom?

Yes! You can grow a cactus in the bathroom! The bathroom is actually a great place to keep a cactus because they can draw in moisture from the air as needed. However, as with growing any cactus, make sure it has ample light.

If your bathroom is south or east facing, or has windows with ample sunlight, you will definitely be safe placing your cactus in your bathroom. However, if your bathroom does not get ample sunlight, you may want to consider using an artificial light or choosing a cactus that thrives in low light.

While cacti are known as a desert plant that enjoys hot and dry environment, there are actually some cacti that thrive when placed in a bathroom with low light and high humidity. Those types of cacti include orchid cacti, mistletoe cacti, and more. Some research on your specific type of cactus and its light, water, and environment requirements would help make sure that it will thrive in your bathroom.

There are also many different places you can put your cactus in the bathroom. While the amount of light is the most important aspect in finding a place to put your cactus, you are not limited to just the window sill. You can place a cactus on a shelf or on your countertop, on the back of your toilet, or even hanging by the window. The possibilities are endless!

Adding any kind of greenery or foliage to your bathroom can actually be beneficial. They can improve air quality by removing pollutants, boost your energy, and improve your mental health. Not to mention, when you put a plant in a humid bathroom, they absorb the extra moisture in the air which helps it grow. It’s good news for anyone who tends to forget about watering their plants!

Related Questions

Other than plenty of sunlight, what does my cactus need to thrive? Water. While your cactus doesn’t need a lot of water, it still needs some to survive. A good rule of thumb is to water your cactus when the soil seems dry. Water your cactus thoroughly and if it soaks up the water fast, dowse it one more time. Usually, Cacti need water at least once a week.

If your cactus is not getting enough water, the leaves will begin to pucker, shrivel, and become discolored. If your cactus has been watered too much, it will feel mushy, begin to brown, or experience root rot.

Does the temperature of my home affect my cactus? Yes. Cool temperatures can lead to water being absorbed slower and it sitting in the pot much longer which could lead to root rot. As temperatures change, make sure you are checking the soil before you water your cactus and do not water it unless the soil is dry. You may only need to water your cactus once a month if it is in a cool environment.

As temperatures change, make sure you are checking the soil before you water your cactus.

Hot temperatures can affect cacti, as well. While they are desert plants that thrive in hot environments, hot temperatures mean the water will dry up much quicker. If the temperature in your home is on the warm side, you may need to water your cactus more than once a week. A high temperature, especially for a cactus sitting in a window, can also lead to burning.

Does A Cactus Need Sun? Shine Your Cactus with the Following Tips

Cacti and other succulents are among the most common houseplants. But, away from the home conditions, these plants have learned to compete for survival all over the world. Most of them are desert plants that have learned how to survive the scorching sun and sporadic rainfall. 

So, does a Cactus plant need sun? Cactus love to be near the window two blossom. You need to ensure that you give your cacti and other succulents the brightest window you can afford in your home. A south facing position will provide good sunlight, and the optimum light depends on the variety of cacti that you are growing.

Cacti come in a wide range of shapes and sizes and tend to grow best in lots of light, high temperatures, low moisture, and good drainage.

However, not all cacti grow in deserts. Some of them, such as the Schlumbergera grow in the rainforest conditions of North and South America and prefer semi-shade and humid conditions.

So, do cacti plants need lots of sunlight to blossom in your home? In this simple guide, we help you debunk the common myth that cacti need lots of sunshine to thrive.

Furthermore, we shall teach you how to take care of your cactus plant by understanding its light requirements and how to ensure that it gets the right amount of light throughout the year.

Read on to find out everything that you need to know.

Do Cacti Plants Need Sunlight?

Generally, succulents, including cacti, love sunlight, and it is always a good idea to position your cacti in a relatively bright place. Although some cacti species such as Rhipsalis and Hitora can tolerate lower light levels, no cactus loves to sit in the dark rooms of your house or on your dark office desk.

Finding a bright spot in your home is the first step in establishing whether you can take care of cacti or not.

Cacti plants can behave quite strangely if they don’t get sufficient sunlight. In most cases, you will notice discoloration in your cactus plants if they need more light. The deep green cacti will slowly fade to pale green while the purple, yellow, or bright pink cacti will revert to plain green.

Insufficient light will also affect the overall growth habit of your cacti. What was once a short, dark, and healthy cactus plant may start to grow tall and pale as it tries to reach for more light.

This will soon lead to strange growth patterns that may cause new growth to be much smaller than the rest of the plant or sometimes, new branches will come out that are quite long and tendril-like.

The unusual growth pattern in cacti is often referred to as etiolation and can only be avoided if you move your plant to a place where it will receive sufficient sunlight.

How Much Light to Give Cactus

Light is a funny thing since it is hard to measure it. If we were talking about water requirements, we could say that you need to pour one or two cups of water on the plant once or twice in a day, but it is not like you can give your cactus plant 7 lbs of light every day.

It simply can’t happen that way. So, how can we measure the amount of light to give to your cacti?

Well, the best approximation that we can use is to measure the duration. How long should your cactus plant be exposed to light each day? And to make things more precise, you need to understand how much of what kind of light keeping in mind that there is natural and artificial sunlight.

Fortunately, we are here to simplify things for you and ensure that you take good care of your cacti. So, let us start with the basics.

Cacti and other succulents need to have between 10-14 hours of light a day. Don’t expose your cactus plant to more than 14 hours of light in a day. On average, 12 hours of light a day is enough to keep your plant happy.

Remember the fact that your plant needs rest too and exposing it to more than 14 hours of light a day won’t help it in any way. In fact, cacti plants need darkness to take in carbon dioxide that will be used in the process of photosynthesis during the day.

 Know Your Angles

One of the most critical things that you are supposed to do before you even go for that cactus plant is to understand which way your house faces.

If your house faces north or south, that is great because you get all that southern exposure. However, if your home faces east or west, it is going to be a little bit trickier since the east-west sunlight isn’t as bright or as hot compared to the north-south sunlight.

If you are lucky to have a north or south facing house, make sure that you study the sunlight for several days to determine how many hours of sunlight you get in a day.

This will guide you on which type of cacti to go for and what to avoid. Some cacti such as the blue cactus usually require several hours of unrelenting hot sunlight to thrive.

If your house is facing east or west- meaning that you get a less amount of sunlight- go for the darker species of cactus plants since the darker the cactus plant, the less light it needs to survive.

First, understand which way your house faces

Direct vs Indirect Sunlight

One of the most critical aspects of light you need to consider while taking care of your cacti plants is the intensity of sunlight.

Cacti, like us humans, prefer to bask in direct sunlight rather than indirect sunlight. However, too much direct sun can cause serious damage to your cacti and even lead to death.

Direct sunlight refers to the rays that are directly hitting the plant and is quite strong. Therefore, you need to ensure that your cacti plants get enough direct sunlight but not too much of it.

On the other hand, indirect sunlight refers to filtered, scattered light that is not directly hitting the plant. These rays are weaker than direct sunlight and may barely be enough for your cacti to thrive in.

Therefore, if you are keeping your cacti indoors all the time, ensure that it gets enough indirect sunlight from a nearby window or balcony.

Seasonal Light Differences

The other crucial aspect of light that you need to keep in mind while taking care of your cacti plants is that light levels and intensities differ from season to season.

Summer days can be quite long, and the light intensity is also strong. Therefore, the most critical factor in your summer months is sun exposure. But, you must strive to understand how much sunlight your plant is getting every day as well as the temperature and humidity.

Although they survive in deserts, cacti and other succulents can get scorched and dried out quickly if the sun rays are too intense. You need to be cautious while moving your plant from shade to full sunlight.

Sometimes, the plant can’t withstand the sudden change in the intensity of light and will die even if you think that you have done the right thing to help it. When introducing your cactus plants to new climate or light intensities, make sure that the process is gradual.

You need to take a lot of precaution during the cold months.

During winter, the days are shorter with less intense light. If your cacti become a little bit dormant in winter, don’t worry about it.

However, you need to know the right time to keep your plants indoors and take proper precautions when you transfer them outdoors.

If temperatures in your region are going to fall below 500F, then it is time to find a perfect window indoors for your cacti plants.

Most importantly, you need to take a lot of precaution during the cold months, especially if it has rained. Sometimes, the wet soil mixed with the relatively cold temperatures can quickly cause your cacti to die.

Many people prefer rotating their cacti between indoors and outdoors as the seasons change just to make sure that they don’t get hurt.

Sunlight vs. Artificial Light

This is a big topic when it comes to growing cacti, but the truth is that neither sunlight or artificial is better than the other. There are situations when sunlight outshines artificial light and vice versa.

Sunlight is amazing since it right there, and it is also free. You can simply put your cactus plant on your windowsill, water it when you remember, and it will thrive. Sunlight has always been there, and the cactus plant is well equipped to harness it and use it appropriately.

In fact, cacti plants were born to bathe in sunlight, and they have a wide range of colors that enable them to absorb different wavelengths and fascinating adaptations to protect themselves when the sunlight is too scorching.

Sunlight is amazing since it right there, and it is also free.

Therefore, you will never go wrong when you choose to expose your cacti plants to lots of sunlight whenever possible. If you are in the northern hemisphere, you will notice that you experience prolonged hours of sunlight and that could be a significant advantage to your plant. 

If your house is facing east or west, you should prioritize placing your plants in windows facing east. The sun rises in the east, and typically, the strongest sunlight is in the first half of the day.

You should also take into account external factors such as buildings or trees that may cast shade on your windows hence limiting the amount of sunlight that your plant receives.

Position your cacti as close to the glass window as possible since every inch closer to the light means more light and a happy plant. Keep the glass clean to minimize the amount of blocked or diffracted light.

While natural sunlight is great, artificial light can also help your cacti to thrive. If the light doesn’t penetrate well into your house or have simply run out of windowsill space, then you have no choice but to embrace artificial light as the primary source of light for your cacti.

Artificial lights are also great for propagating since they are less intense and you can use specific light wavelengths to encourage fruiting or flowering.

But, unlike sunlight, artificial lights aren’t free since you have to buy the bulbs and foot the electricity bill. The different types of artificial light that you can use to make your cacti happy include fluorescent, LED, and incandescent lights.

While natural sunlight is great, artificial light can also help your cacti to thrive

How Long Should I Keep the Artificial Light On?

When it comes to artificial lights, you should keep them on for 12-16 hours per day. The intensity and duration of the artificial light should be adjusted as days become shorter or longer to ensure that your cacti plants get enough light during all seasons.

Also, pay close attention to the type of artificial light you choose since it will determine the length of time your cacti should receive light.

For example, incandescent and halogen bulbs don’t need to be kept on for long since they have a low intensity, while LED and fluorescent lights are more powerful; hence, they can stay on longer.

Be Wary of Sunburn

Although most succulents and cacti can handle intense sunlight, extreme temperatures and direct exposure to the sun can lead to sunburn. Common signs of sunburn in cacti include wrinkled leaves/stems, discoloration, and pitting.

It is hard to reverse the damage that has been caused by sunburn. Therefore, you must always be careful when growing cacti outdoors and ensure they don’t get too much direct sunlight.

When transferring your plant outdoors, you must do it gradually and keep an eye on your cacti for any adverse reactions such as sunburn.

Keep in mind that not all cacti have the same ability to resist light intensity. If you are growing a variety of cacti plants, pay close attention to the individual characteristics when it comes to light exposure.

For instance, some cacti, such as the Mammillaria elongata, can handle very intense sunlight, while others, such as the Echinopsis hybrid, prefer filtered light.

Therefore, it is prudent to use a shelter or keep them well-watered to minimize direct contact with intense sunlight and create an ideal microclimate for your cacti.

Final Thoughts

When it comes to taking proper care for your cacti plants, light plays a critical role. Being desert plants, cacti require a significant amount of light to stay healthy throughout the year.

Typically, a cactus plant needs approximately 12 hours of light each day to avoid etiolating.

During summer, sunlight can be a good source of light, but you need to be careful since the increased intensity of the sunlight can cause your plants to die. However, artificial light comes in handy during the cold winter months.

Also, if you are living in an area that doesn’t receive much sunlight, artificial lights are the way to go. Whether you depend on natural sunlight or artificial lights, the most critical thing is to ensure that your cacti receive the right amount of light needed to stay healthy.

Can A Cactus Grow Indoors? 5 Easy Tips To Do It Right

With the fantastic benefits that a cactus comes with, I recently decided to do a bit of research on the plant. I always wondered if it’s possible to grow cactus indoors. So, I decided to research a bit, and today, I want to share my findings with you. 

So, can a cactus grow indoors? Cactus can grow indoors In fact, all the different varieties such as the forest, desert, and Christmas cactus can do well indoors depending on how you take care of them. How healthy they grow depends on if they are getting enough sunlight and you are not overwatering them. 

How can you grow cactus – a plant adapted for the desert indoors?

The biggest motivator for growing cacti should be because they are easy to maintain as they don’t require a lot of work. Succulents will mostly die during the winter due to too much water. Therefore, there is a need to keep them indoors and without water often. 

1. Growing forest cacti

These types of cacti grow in tropical and subtropical areas globally. Tropical regions are areas such as Mexico, parts of South America, and Caribbean islands. The Christmas cactus belongs to this group.  

For people looking for hanging plants, this is a great option. When they bloom, they produce flowers in lilac or pink colors.

Use these tips to help you grow the forest cacti:

  • Drainage: The pots should have drainage holes in the container and ensure soil drains well for them to grow well. 
  • Light: these cacti love sunlight but not the direct one. During summer, you can move them outside on the porch which is unheated until when the temperatures get below 50 degrees. 
  • When the plant is flowering, water regularly. During the resting period, only water them when the soil is dry on touch. 
  • To encourage branching and flowering, prune in June. You can also use the pruned ones to grow more cacti. To grow more cacti, just cut them and place them in vermiculite as they root easily. 
  • In the case that your cactus is not blooming, it could be because of the temperature of light they are getting. Keep the temperature at 50-55 F then resume watering and move it to a warmer location.

2. Growing desert cacti

Desert cacti species are quite a variety. Whether they grow or not depends on how well they are taken care of. Just like the forest cacti, the desert ones require intense light most especially during winter. 

You can follow the pointers below towards having healthy desert cacti:

  • During the active growth period, you need your cacti to stay in temperatures from 70 F and above. You may notice scorching if it had not been hardened before. 
  • The blooming stage is quite sensitive, and you only water them when they start shriveling. When you water, make sure you water well. Note that some species bloom better when they are underpotted. 
  • During the growing season, it’s essential to consider a cacti fertilizer. Use one that’s specially designed for cacti.

5 Easy-to-do Tips to growing cactus indoors

Cacti come in different colours ranging from blue, green and grey. How you take care of them is what determines if they are healthy or not. Watch out for the tips below to help you grow cactus indoors. 

1. Use fertilizer

Using an appropriate fertilizer meant for cactus helps in its growth. Use a low-nitrogen but soluble fertilizer. The best time to apply the fertilizer is when you notice new growth. This can be done every 2 months, three times. 

Do not apply fertilizer on a recently potted cactus. Wait until you can see some growth before the application process. 

Not that, there are some species that grow during winter. Unlike fertilizing during summer, for these species, work your schedule to fertilize them during winter. 

2. Choose colors wisely

Naturally, green cacti are more tolerant to environments with low light. If your room is well-lit, you can go for cacti that are pink or purple. However, if your room has low light, go for the green ones.

3. Supplementing light

Cacti do well with natural light. However, during winter, there’s not much light. Glowlights can act as a supplement for the natural light for the few months before its summer again. This ensures your cactus grow healthily. 

4. Propagation

There are different ways to the reproduction of cacti. You can cut leaves from an already grown cactus, use seeds or graft. Grafting is mostly done for weak cacti species or those that are hard to propagate. 

5. Watering cactus

Cactus will always rot if you overwater them. During spring and fall, cacti will need regular watering. However, during summer, they will need less water, maybe once a week. A cactus may turn pale if it is deprived water, adjust according to its needs.  

Dealing with common cactus problems

There are common cacti problems which can be resolved to ensure they are healthy. 

1. Yellowing or bleaching

It is common to find cactus turning yellow or white. What this means is that the plant is getting excess sunlight. Remove the cactus away from direct sunlight and place them in probably a window that has less sunlight. It should improve with time.

2. Thinning

Other times, you’ll notice the top of the cactus thinning or it growing towards the direction of the light which may cause an imbalance. This means it is not getting enough light. Move the cactus to a location where it will get adequate light for healthy growth. 

3. Pests

Some of the common pests that attack cacti are mealy bugs, scale insects, spider mites, and fungus gnats. It can be challenging to control these pests because they hide in places that are hard to notice, and also because they may have grown resistant to pesticides. 

Mealybugs are found usually in clusters and are most likely to be on the leaf veins. They mostly suckle the root juices causes the cactus to rot because of bacterial infections. 

Scale insects are usually located on the leaves and stems of the cactus and can be scraped off. 

Fungus gnats look a bit similar to mosquitoes and hover above the soil surface in the pot. During the larval stage, they usually live in the soil and are more likely to cause root damage because they consume the organic matter in the ground. 

Spider mites look like dust and can easily damage the cacti epidermis. They suck the cactus juice. If the plant is infected, there will be some small brown dots and webbing. 

Pest control 

Controlling pests can be a daunting task, especially if some of the pests are resistant. One sure way to reduces the chances of pests invading cacti is by growing them healthily. Keep them in the right conditions, such as placing them under the right amount of light and watering just enough. 

  • Mealybugs and spider mites can be washed off. First, cover the soil that’s in the pot with something waterproof and then wash the pests off.
  • Hygiene is equally as important. Keep dead leaves away from the pot to avoid attracting any pests. 
  • To contain the pests, spray the cactus with a dilute solution containing alcohol (preferably a ratio of 1:3) Be on the lookout because this solution can damage sensitive cacti. First test on a small part of the cactus to see if there is a reaction before spraying the whole plant only for it to damage the plant’s epidermis. 
  • Sticky traps that are precisely yellow can be used to control fungus gnats. 
  • Insecticidal soap is also another option. You can spray the plant. However, waxes and oils from the plant can be damaged by the detergent. Read the instructions to see if it’s safe to use the soap on your plant. A test on a small area of the plant is also recommended. 
  • Insecticides such as neem can also help but always read the label before using anything that could potentially damage the cacti.
