Growing a cactus inside your house does not only beautify your indoor spaces but also gives a refreshing aura to your home. A lot of people find it quite relaxing to see a beautiful plant such as cactus in the middle of the center table or the four corners of their living room. However, some gardeners are afraid of growing cacti in their homes since they aren’t sure if these plants are safe for their kids or not.

So, is cactus poisonous to kids? Most cacti species are safe for both humans and animals. Their toxicity levels are quite low, but the spines and needles are quite dangerous. The best way to know if your plant is poisonous is by determining its species. There are a few species that can potentially pose a significant danger to your kids. If you don’t know the type of cactus you own, be sure to seek immediate medical attention if your child accidentally ingests the plant.

In this post, we discuss everything you need to know about the safety of cacti plants and what you can do to keep your kids safe. We shall also highlight some of the cacti species that are poisonous.

Are Cacti Plants Poisonous To Children?

Due to the sensitivity of some cacti plants such as the Christmas cactus, they need an indoor environment to thrive. The stems and leaves of such plants cannot be exposed to direct sunlight. However, before you take this step, you will want to be sure about the safety of the plant, especially if you have kids and pets in your home.

Research shows that plants have been one of the world’s leading poison contributing factors inside homes. A significant number of indoor plants have been found to contain substantial amounts of toxins that may be harmful to humans.

But, does it mean that all cacti plants are poisonous? No.

The good thing about most cacti species is that their toxicity level is almost zero. You don’t have to worry about the effect of the plant on your family’s health. In fact, this is one of the top reasons why a significant number of people out there prefer growing cacti indoors.

In some rare cases, infants may be sensitive to the Christmas cactus, but it doesn’t mean that it will cause any harm to them. The plant is absolutely safe for your baby, and there is nothing to worry about.

However, there are certain times when small kids may try to ingest the cactus while playing. For precautionary measures, make sure you position your plant in a slightly elevated area where your kids cannot reach easily.

Although the plant may not contain toxic elements, it is definitely not fit for human consumption. Only the fruits of a few cacti species are edible.

Poisonous Cacti

One thing you should note is that not all cacti plants are safe. Although most of them have amazing features, some of them are also not safe at all.

By poisonous, we are not referring to the leaves and spines even though their spines are quite dangerous as well if they find their way into your skin.

Keep in mind that the spines serve as a defense mechanism to protect the plant against predators and also serve a reproductive purpose. They usually cling onto a host, and when they fall off, they start growing into new plants .

So, how are these plants poisonous? Well, some cacti plants are highly corrosive to the human skin, and when they are ingested, they may a wide range of illnesses. These are the plants you need to watch out for and, if possible, avoid them completely.

While you may have had no need to research before buying your cactus plant, the dynamics change if you have kids and pets in your home.

Take time to establish safe cacti species to grow at home and generally avoid the following species that are poisonous:

1. San Pedro Cactus (Echinopsis Pachanoi)

The San Pedro cactus is known for its beautiful flowers and spines. It mostly grows in the Andes Mountains in Argentina, Chile, Ecuador, and Bolivia. This cactus species is mainly used for healing and recreation purposes, but it contains high amounts of mescaline and other psychedelic alkaloids.

Mescaline is listed as an illegal substance in most countries since it is known to cause hallucinations when ingested.

The chemical substance can also distort one’s thought process. Therefore, it not advisable to grow the San Pedro cactus in your home because it can cause devastating effects to your kids when they ingest it.

Some of the side effects that one can suffer from ingesting this cactus include dizziness, stomachache, nausea, vomiting, and palpitations.

2. The Peruvian Torch (Echinopsis Peruviana) Cactus

The Peruvian Torch is widely known for its relatively fast-growing nature. This cactus species grows large spines and is mostly found on the slopes of the Andes Mountains in Peru.

This plant is named after one of the famous cities in Peru. It is easy to cultivate as a home plant, but you should avoid it if you have kids or pets to protect.

A unique feature of the Peruvian Torch that makes it attractive is the gorgeous flowers that grow near the top of the stem. Its flowers open up at night and have a relatively strong fragrance.

However, ingesting this cactus can be dangerous since it is known to cause hallucinations and a wide range of disordered thoughts. You can still cultivate the Peruvian cactus as an outdoor plant, but make sure you keep it away from your children and pets.

3. Peyote Cactus (Lophophora Williamsii)

The Peyote cactus is one of the few spineless cacti species you will come across. While you may assume that the cactus is safe because it has no spines, the opposite is quite true. Peyote cactus is a slow-growing plant that is mostly found in the western parts of the USA and Mexico.

This plant is traditionally used to heal illnesses such as diabetes, fever, childbirth pain, skin diseases, and rheumatism since it contains mescaline.

However, the same mescaline content has psychoactive properties. When ingested, one will start feeling psychoactive, and the side effects may be adverse.

For instance, an overdose of peyote cactus can lead to a psychotic breakdown, which is quite dangerous for individuals with mental problems because it aggravates the issue.

The plant also has strong emetic effects and a bitter taste that can be nauseating hence the need to keep it away from kids. Peyote cactus is also known to cause variations in breathing, blood pressure, papillary dilation, and heart rate.

4. Canary Islands Cactus (Euphorbia Canariensis)

The Canary Islands Splurge cactus is a top choice for many gardeners because it is relatively easy to maintain and does well in well-drained soil and full sunlight. In fact, this is one of the few low-maintenance cacti plants you may come across.

It is named Canary Islands Splurge because it mostly grows in the coastal belt of the Canary Islands. It thrives in extremely cold temperatures and produces beautiful flowers along its edges.

Even though it is lovely and easy to grow, you will rarely find Euphorbia Canariensis in homesteads for obvious reasons.

The plant is highly toxic and cannot be consumed. In fact, it produces a milky sap that irritates human skin and eyes. Handling the plant requires great care since any slight breakage will expose your skin to its milky juice, which might result in severe skin burn.

If ingested, the sap can cause cold sweats, sneezing, and even fainting.

5. The Cholla Cactus

The cholla cactus shoots like needles and is commonly found in the desert regions of the southwestern United States and northern Mexico. It grows in dense clumps with long stems that can reach heights of up to four feet tall.

The cholla cactus produces edible fruits, but its spines are highly dangerous and irritating, so you should never touch it unless you have protective clothing. To make matters worse, the spines are barbed and will break off in your skin when touched.

The cholla cactus is known to cause severe allergic reactions in humans, including hives and swelling of the face, lips, and tongue. If ingested, it can also affect your digestive system since it releases a toxin that causes intense stomach pain and vomiting.

It is also poisonous to animals. Since the spines are highly dangerous, it’s best to keep cholla cacti away from children and pets at all times, so they don’t get hurt or poisoned.

Are Cacti Plants Poisonous to Pets

Just like kids, you need to be cautious when exposing your pets to a cactus plant. Some pets love eating plants, and you will want to be wary of the harm it can cause to your pet.

Fortunately, most cacti species are safe for your pets, but you will still need to avoid the poisonous species mentioned above. Generally, cats and dogs find plant leaves and flowers attractive. The worst can happen if your pet was to ingest a poisonous cactus.

The best thing you can do with your pet is to make sure it cannot reach the cactus plant at all. Keep everything away, and don’t hesitate to contact a veterinary officer in case your pest ingests your plant.

Precautionary Measures Recommended to Keep Your Kids Safe

Even though we have mentioned that a significant number of cacti species are safe, it is still important to take precautionary measures to keep your little ones safe. To be safe, make sure you do the following:

Keep all plants out of reach of young children
When spending time outdoors with your young ones, teach them to stay away from plants and not eat any non-food items
Do not assume that a plant is safe for your kids just because you think so.
Leave tags on all plants and other items you bring home from a plant nursery. If you don’t know the names of the items, ask an expert at the plant nursery to help you identify them and get a name tag for each item
Make sure your children’s caregivers know the names of all plants inside and outside your house

Can Cactus Needles Kill You?

Cactus needles are pretty dangerous because they are sharp and cover a relatively large surface area. They can easily cause puncture wounds, skin infections, and rashes in humans.

However, it is highly unlikely that cactus needles can cause death if you take proper precautionary measures and avoid touching them with bare hands.

If you are exposed to a high number of cactus needles or their toxins, then it is possible that you could experience an adverse reaction that leads to death.

You should seek immediate medical attention if you experience severe reactions such as difficulty breathing, throat swelling, dizziness, or confusion.

Is Cactus Water Poisonous?

Besides sharp needles, cactus plants also contain a type of sap called cactus water. This liquid is stored in the plant’s stem and leaves and can be toxic if ingested by humans or animals.

The water contains a toxic substance known as saponin, which can cause severe gastrointestinal issues if ingested. In extreme cases, it can also cause kidney failure or death.

Cactus water is also known to cause stomach irritation and vomiting when consumed, so it’s best to stay away from it entirely. Avoid contact with your eyes, nose, or mouth when dealing with cactus water.

If you come in contact with the liquid, wash your skin and eyes immediately with running water and seek medical attention for any poisoning symptoms.

What Is the Most Dangerous Cactus?

The most dangerous cactus is the cholla, which is native to the Southwestern United States and Northwestern Mexico. This cactus has sharp spines that are barbed and hooked, making them particularly dangerous as they can easily stick to the skin.

If you come in contact with a cholla, it’s best to use tweezers or a pair of pliers to remove the spines and seek medical attention if you experience any signs of infection.

Other dangerous cacti include the jumping cholla and some species of Euphorbia. It is essential to avoid contact with these cacti as they can cause serious injury, illness, or even death.

Final Thoughts

Although cacti plants are an incredible option for indoor plants, they are not 100% safe. Therefore, it is essential to take all necessary precautions to keep them away from your kids and pets, and anyone that can negligently ingest them.

Before you purchase any cactus plant, conduct thorough research to establish its safety, especially if you have kids at home.

How Do You Know When A Cactus Needs Water?

February 16, 2026April 10, 2020 by Cactusway Team

Cacti are relatively easy-to-grow plants that can survive for a prolonged period in drought conditions. However, it doesn’t mean that they are indestructible just because they originate from the desert. Prolonged drought can be catastrophic, and that is why you need to understand dehydration signs to look out for in your plant needs.

So, how do you know when a cactus needs water? Well, to know if your plant needs water, you need to observe its behavior carefully. Typically, if a cactus is under-watered, its body may look wrinkly and feel somehow “soft.” The spines (modified leaves) feel dry and may easily fall off. Dry leaves caused by lack of enough water are usually softer to touch than when they are adequately hydrated but don’t look soggy and translucent like overwatered leaves.

In this post, we would like to share with you some of the common signs of a dehydrated cactus plant and how often you need to water your plant for it to thrive.

How Do You Know If Your Cactus Needs Water?

If you want to know how to tell when your plant needs water, you need to understand how cacti plants are different from other plant species. The primary characteristic that makes these plants different is their ability to store water for a relatively long period.

Cacti plants have specialized stem cells that hold onto water whenever there is a downfall in the desert. This means that once you water your plant, these cells absorb water until every cell is fully hydrated.

Over time, the plant will utilize the water stored in its cells, gradually reducing the hydrostatic pressure inside the plant cells and tissues.

A water can beside the cactus, — You must learn how to tell when the hydrostatic pressure is relatively low.

As long as the plant’s water reservoir hasn’t been exhausted, it will prefer dry, airy soil. This is the primary reason why it is highly recommended to grow cacti plants in porous potting mix.

Problems arise when you grow these plants in wet and humid areas where soils don’t dry up quickly in between watering sessions. You may also encounter problems when a drain hole in your pot blocks or if the holes are too small.

Pots designed for growing cactus must have numerous holes to facilitate quick drying of the soil after watering.

To know when to water your plant, you must learn how to tell when the hydrostatic pressure is relatively low. So, how can you tell when the hydrostatic pressure is low?

1. Visual change

When a cactus is fully hydrated, it will stand up to its full height and appear healthy. However, many of them start to show signs of distress when the internal hydrostatic pressure drops significantly.

For instance, some cacti species will start to fold into half then after watering, they straighten up again since the hydrostatic pressure is back to normal.

A top image of a cactus. — Cactus will start to show signs of distress when the internal hydrostatic pressure drops significantly.

Other species may show signs of wrinkles on their skin caused by reduced tissue volume. Sagging tips, drooping leaves or subtle leaning are some of the common signs of reduced internal moisture and a clear indicator that your plants require watering.

2. Physical touch

Another way you can tell whether the hydrostatic pressure of your plant has dropped is by touching it and taking note of how it feels. A fully hydrated cactus plant feels “hardy” and regains its shape quickly if you press it slightly.

If you haven’t done this before, start by watering your plant, let it rest for a few hours then press it several times to understand how it feels when it is hydrated. Let this serve as a basis for your future comparison.

When the stored water is used up, the plant tends to soften up due to significant loss of hydrostatic pressure. The plant will easily yield to your touch while in this state.

However, you should be worried if your cactus is softening unevenly since it could be a sign of invisible root rot spreading through the healthy plant tissue.

3. Water when the soil is completely dry

The first step to keeping your cactus plant happy is ensuring that your potting mix is fast-draining and has plenty of inorganic materials. From there, you need to make sure that your soil is completely dry before you water your plant.

Fortunately, checking if your soil is dry isn’t difficult. The easiest way of checking is by sticking your finger into the container. Be sure to go down at least two inches and note how it feels.

If the soil feels wet, damp, or slightly colder than the surface, do not water your plant. Instead, give it a few more days and check again before you consider watering.

The other way of checking the level of dryness of your soil is by using a soil moisture meter. A moisture meter is a simple device that records the soil moisture content.

Be sure to go for a quality moisture meter because the cheap ones can be quite inaccurate.

4. Watering method

Did you know that your watering method can have a significant impact on your plant? Experienced gardeners agree that there are a lot of o problems caused when you water your cactus plant from top to bottom like other ordinary potent plants.

With this watering method, water travels down the edges of the soil mass and out the bottom, which leaves too little behind for actual absorption. In fact, some cacti plants develop rot right at the soil line due to this kind of watering.

The best way to water your cactus to ensure it stays longer before dehydration is to set the pot in a pan of water. This way, you allow the soil to absorb as much water as possible, which in turn boosts the plant’s absorption rate.

Once the moisture moves up to the surface of your potting mix, carefully take the pot out of the water pan and let it drain.

How Often Do You Need to Water Your Cactus?

One of the most dangerous things for your cacti plants is watering them incorrectly. Keep in mind that these plants hold water in their stems and tissues. They use stored water to survive for prolonged periods before they need another watering session

Too much water is deadly for your plant. In fact, it is much easier to recover from underwatering than overwatering. However, leaving your plant too dry for prolonged periods can easily cause their roots to die.

The best way to determine if it is the right time to water your plant is by examining the soil and feeling the moisture level. As mentioned earlier, don’t just touch the surface of the soil and make a decision. Dip your figure deep down the potting mix to see if it is scorched.

How much and when to water your plant will also depend on the season. During the growing season (spring and summer), when most cacti plants are active, you need to water the plants regularly and thoroughly.

For most indoor potted plants, watering at least once every ten or 14 days during the active growing season should be okay.

During the inactive season (mostly winter), you only need to water it a few times. Typically, watering your cactus at least once per month will be sufficient.

Pay close attention to how your cactus looks during this period. If it starts to appear shriveled between watering, you should consider watering it more.

Watering After Initial Planting

Once you have your plant in the right pot with a good potting mix, you need to water it properly, so it picks up. Be sure to soak the container in plenty of water and let it absorb as much after as possible. After all, the first watering after planting may be the most critical.

However, it is still important to allow the plant to drain even if you are watering it for the first time. Don’t be tempted to leave a dish under your pot or block some holes because it encourages rotting.

Watering Outdoor Cactus

Outdoor plants tend to have slightly different watering needs because they are constantly exposed to various weather conditions. As a general rule, make sure you water your outdoor plants at least once every seven or ten days during spring and summer.

Before watering, take time to feel the soil moisture and make sure the potting soil is completely dry. Water your plants thoroughly until you see excess water seeping out of the drainage holes.

Depending on the type of your container and soil, you may not always see excess water flowing out of the drainage holes.

During the inactive seasons (fall and winter) water your plant less often and lightly. Consider watering only once every three or four weeks.

The best time to water your outdoor plants is early morning. This allows it enough time to dry out during the day. Watering early morning also enables the water to penetrate through the soil quite easily, hence reaching the roots.

Final Thoughts

The notion that cacti plants require little to no water at all to survive has caused the death of many plants due to dehydration. Although these plants are drought-resistant, it is good to keep in mind that they can easily die if you don’t provide them with sufficient water.

Do not treat your cacti like other traditional plants that depend on perpetual soil moisture to thrive.

Always remember that your plant has a unique way of speaking to you, and it will clearly show you signs when it needs some watering. All you have to do is learn how to read the signs.

How To Make A Christmas Cactus Bloom? Here are the secrets

February 16, 2026April 4, 2020 by Cactusway Team

If you are like many gardeners out there, then a Christmas cactus must be one of your favorite plants. The lovely flowering cactus is one of the few cacti species that originate from the forest. While this is an attractive plant to have all year, its real magic is displayed when it starts to bloom. Unfortunately, getting your Christmas cactus to bloom when you want it can be quite a challenging task unless you know how to do it right.

So, how can you make a Christmas cactus bloom? Well, the secret to getting your Christmas cactus to bloom is providing it with the right temperatures and amount of light. Christmas cacti tend to flower in a cold and relatively dark environment. To initiate the production of flower buds, make sure you expose it to at least 16 hours of darkness and eight hours of light for at least six weeks. With the right conditions, it can take up to 12 weeks for the first blooms to appear.

In this simple guide, we walk you through the simple steps you need to take to ensure you receive the best show from your Christmas cactus. The information contained here may also apply to other types of cacti as long as you tweak the schedule to accommodate for the different flowering seasons.

The Christmas Cactus: A Quick Overview of the Plant

Schlumbergera bridgessii, commonly referred to as Christmas cactus, is a type of succulent that originates from the tropical rainforest of Brazil. Some people love to call it the crab cactus thanks to its leaf-shaped stem segments that feature curved pointed teeth along the edges. The Easter cactus is closely related to the Christmas cactus, but it has rounded edges on its leaf segments.

Christmas cactus is usually classified as epiphyte because it thrives above the ground in areas where tree branches meet and decomposing fallen leaves collect. Even though this plant bears the name of a cactus, the care it needs has nothing to do with the typical desert cactus. To be more specific, this plant is classified as forest cactus.

The plant grows well when it is pot bound and prefers a rich and organic potting mix. Never allow the potting mix to dry out if you want to keep it alive. Also, once you notice that it is growing bigger and bigger, you should plan how to move it up to a larger container.

Christmas cacti do well in bright, indirect light. Avoid exposing it to direct sunlight because the intense heat can easily cause sunburn to its leaf segments.

How to Get Your Christmas Cactus to Bloom

The trick to getting your Christmas cactus to bloom boils down to three critical things: light, temperature, and water. Typically, the bloom season for this plant comes during fall- in the last days of October and the early days of November. This information will help you understand when you should start preparing your plant for the blooming season.

Here are the three critical points you need to be aware of if you want to make your Christmas cactus bloom:

Reduce Watering

To encourage blooms to form, you need to start limiting the amount of water your plant receives. The only thing you need to do is to keep the topsoil moist, not waterlogged. Water the topmost layer of your potting mix, which is approximately one inch only when it is necessary.

Keep in mind that too much water may cause the buds to fall. You should only water the plant when the topmost soil layer (about one inch or 2.5cm) is completely dry to touch. Minimal watering will encourage the plant to enter dormancy, which is a critical stage for getting your plant to bloom.

Feed Your Cactus

Although Christmas cactus is known to survive without fertilizer, feeding your plant with slow-release or liquid fertilizer will help promote flowering. Preferably, feed your plant every two weeks from mid-summer until it stops blooming.

Use organic liquid fertilizer to ensure that the Christmas cactus takes in all the essential nutrients for healthy growth and bloom production.

Compost tea and fish emulsion are some of the best options for indoor plants like Christmas cacti.

Alternatively, use a slow-release fertilizer during the blooming season. Be sure to follow the instructions given on the packet when feeding your plant and read the labels carefully. Do not overfeed your cactus plant because it will affect its growth.

Provide Enough Lighting and Darkness

Apart from watering, you will need to ensure that your plant receives the right amount of light and darkness. To bloom, your plant requires between 12 to 14 hours of uninterrupted darkness for at least eight weeks.

This period should start from mid-September to the end of October or early November. Exposing it to some indirect bright sunlight during the day is okay, but you have to ensure that it receives at least 12 hours of absolute darkness at night.

After this period of exposing it to intense darkness, it will take approximately six weeks for you to start seeing the flower buds. If you are growing your Christmas cactus indoors, do not turn on the lights at night even for a second because it breaks the dark cycle required.

Cool Temperature

Limiting watering and placing your cactus in a dark room isn’t all that is needed to make it bloom. You also need to keep the surrounding environment as cool as possible. Typically, you should work towards keeping the temperature to an average of about 50-55 degrees F.

This should happen every night from mid-September to the end of October. Therefore, it is critical to ensure that the location where you have stored your plant provides both the right light and temperature requirements.

"COOL" Lighting. — **keep the surrounding environment as cool as possible**, **about 50-55 degrees F**

Avoid Pruning Your Cactus

Pruning or trimming your Christmas cactus is not recommended since it will leave the plant in a weak state which won’t be able to produce blooms.

Even if you want to remove some dead parts from the stems, do so very carefully and only when necessary.

The best time to prune your Christmas cactus is after it has bloomed. This way, the plant will have enough time to recover and adjust from the pruning process before it slides into winter dormancy.

Be careful not to damage the flowers while trimming or shaping your Christmas cactus. If you do, it will reduce its bloom production and, in some cases, prevent them from showing up.

Taking Care of the Flowers on Your Christmas Cacti

If you do everything right, you can be sure to experience a magnificent floral show. But how do you take care of the flowers to enjoy the show for as long as possible? The first thing you need to do is to ensure your plant continues to receive prolonged hours of darkness and cold temperatures for between six to eight weeks.

You should also consider relocating your plant to a relatively sunny and draft-free spot. However, protect it from direct sunlight as much as possible since intense heat may cause some of the flowers to start falling off.

Exposing the plant to brighter, indirect sunlight will encourage it to produce more flowers. Christmas cactus will also bloom better when it is pot-bound.

While watering may be slightly increased during the blooming period, the amount will vary depending on your plant’s current light conditions, humidity levels, and temperature.

The good news is that when you force a Christmas cactus to bloom by providing it with the right conditions and proper care, it may surprise you by blooming several times in a year.

Can a Christmas Cactus Bloom More Than Once in a Year?

Yes. Unlike other types of cacti species, a Christmas cactus can put on the floral display more than once a year if you provide it with proper growth and blooming conditions. For instance, positioning your plant on an east-facing window that receives abundant sunlight during the day and at least 12 hours of darkness every night can make your plant bloom again.

In essence, we are looking at the right balance between light, darkness, warmth, and coldness. The cold evening temperatures may encourage your plant to flower again, even when you least expected it.

Make sure your Christmas cactus plant receives the right amount of darkness and cool temperatures in fall so that it can bloom again in winter. While it blooms, continue to provide the right conditions as it takes long before you can start to see new flower buds sprout.

Why Won’t My Christmas Cactus Bloom?

The holiday season is here, and you have put in place the right measures to ensure you enjoy the most beautiful floral display of the season. But what happens if your Christmas cactus doesn’t bloom? What might be the problem?

Here are some of the common reasons why your Christmas cactus isn’t blooming.

Overwatering

The sad truth is that most of us love to pamper our plants during the summer. While your Christmas cactus may love a drink or two every week throughout summer, it can still survive with less.

It might sound strange, but the truth is that these plants usually need a period of almost-drought to signal it to start preparing for winter blooming. So, if you are a lazy waterier, you might just be helping your plant to bloom.

It is getting too much light

Staring mid-September until the end of October, your Christmas cactus requires at least 12 hours of uninterrupted darkness to bloom. Unfortunately, artificial lights in your house can easily interrupt the cycle of darkness. The easiest way to solve this problem is to relocate your plants to a room that is not often used.

It is too warm

Christmas cacti will need a significant drop in temperature to signal the plant to start preparing for the blooming season. If you have positioned your plant on a south-facing window, which is the warmest spot in your house, try moving it to a north-facing window or near the door.

The stream of cool air that hits the plant when the door is being opened or shut should signal it to start preparing for the blooming season.

It’s malnourished

Your plant may not bloom because it is malnourished or has been given excess fertilizer.

Be sure to feed your Christmas cactus with the right amount of liquid-based nutrients every two weeks during the growing season and reduce fertilizer levels once flowering starts.

You can also consider repotting your Christmas cactus into a new soil mix. Usually, these succulents prefer to stay in their pots for several years, and they may even bloom biannually.

How Long Do Christmas Cactus Flowers Last?

The flowers on a Christmas cactus have an average lifespan of about two to three weeks, depending on how well you take care of your plant.

Generally, when the flower buds are still in their tight bud stage, they last for up to two weeks before finally blooming. Once they bloom and open fully, they’ll stay around for another week before they start to wilt.

When the flowers fade, cut them off to maintain an aesthetically pleasing look on your Christmas cactus.

This will also make the plant focus its energy on other buds that have yet to open up so that it can produce a second round of blooms until the end of winter.

Final Thoughts

Christmas cacti are prolific bloomers that can put on an unbelievable flora display as long as the conditions are right. The flowers form at the end of the leaves, and each flower can last for up to one week.

The best way to make your Christmas cactus bloom is by reducing watering, exposure to light, and keeping it in a relatively cooler spot. The flowering period of these plants can last for up to six weeks and occurs around the Christmas period.

20 Best Cactus Species For Your Indoors / Outdoors Cactus Garden

February 16, 2026November 16, 2019 by Cactusway Team

Cacti are one of the extraordinary plants. Most people prefer them and can be grown either indoors or outdoors. With proper care: watering when needed and having the right potting mix, your cactus can last for decades. They require minimal supervision and are ideal for aesthetics.

As I was researching on cactus species, I wanted to know which species are ideal for indoors and outdoors. I have compiled a list of 20 types of cacti that are ideal for your home.

Indoor Cactus

1. Saguaro Cactus

Also known as Carnegiea gigantea, this particular species can grow to over 40ft/12m in height. The Saguaro is native to the Whipple Mountains, the Sonoran Desert in Arizona, Imperial County found in California and the Mexican State of Sonora.

It has a lengthy lifespan of approximately 150 years. Some may grow their first side arm after about 75-100 years. However, some don’t grow these arms and are referred to as Spear.

It starts flowering in between April and June. The flowers open after sunset and close mid-afternoon.

It can take about ten years for the Saguaro to reach 1 inch in height.

Their fruits are red and are often between 2.4 inches to 3.5 inches. They ripen in June and are edible.

Saguaros are barrel-shaped and have peripheral stems, which are the “arms.” The plant stores water, and the more it stores, the more it expands and becomes heavy. A foot of the Saguaro can weigh up to 90 pounds. A mature one can even weigh about or over a ton.

Watering cactus is an essential aspect of the plant as proper care needs to be taken for it to grow healthy. Water the Saguaro every 10 to 14 days. However, be sure to check if the soil still has moisture before watering it to avoid root rot.

The oldest Saguaro to live is the ‘Old Granddaddy,’ and it was 300 years old when it died.

2. Angel Wings

Also known as Bunny Ears or its scientific name Opuntia microdasys, the Angel wings cactus is native to northern and central Mexico. It is more of a dense-like shrub that’s usually40-60cm tall. The stems range from 6-15 cm long while 4-12 cm broad.

Unlike some other cacti, it has no spines but instead, has yellow or white glochids that are 2-3mm and in clutters. The glochids are thinner than the human hairs and detach when touched. Upon touching, they can cause skin irritation.

The Angel Wings cactus has no central leaves or stems but has individual segments that contain the cactus body. The sections grow in pairs which the new growth resembles bunny ears.

Budding always begins late spring and produces flowers that are 2 inches. The flowers are yellow but slowly fade to peach once they are fertilized.

Since this is a desert cactus, regularly water it when in a new pot to from strong roots. Don’t water it during winter.

Its fruits are safe to eat but should be handled with care, especially when repotting.

3. Rat Tail Cactus

The Disocactus flagelliformis or the Aporocactus flagelliformis is native to Mexico. It can be grown indoors, outdoors, or in greenhouses. It is quite a distinctive species whose long trailing stems branch out and are about 1-2 m long and 8-24mm thick.

The cactus flowers during spring and summer and they are usually red, violet, pink or orange. The flowers are generally 2 inches, which last for a few days.

Due to its trailing stems, the rat tail cactus is grown in hanging pots. It’s easy to propagate it by cuttings as the stems grow so fast.

Full light is necessary for this species. Make sure your pot/container is near or on a south or west-facing window. During summer, when the cactus is blooming, ensure the potting soil is moist. However, during winter, water sparingly; when the soil is dry.

For the temperature, your cactus is just fine at room temperature during summer, spring, and early autumn. However, during winter, keep the cactus in a more relaxed setting.

4. Christmas Cactus

Just as the name suggests, the Christmas Cactus blooms around Christmas. It has hanging branches that are green and flat about 3ft tall.

The flowers are commonly red, lilac, yellow, pink, and white. They are usually 3 inches long. Native to coastal parts of Brazil, this cactus prefers a humid climate.

Christmas Cactus is scientifically referred to Schlumbergera. Proper care will help you see the tips of leaves starting to grow. The tips will then begin turning darker until buds appear. Around Christmas time, the buds will then open to beautiful flowers which are perfect for the season.

They do well in natural light but avoid direct sunlight to encourage blooming. Water them every 3-4 weeks. Only water when the pot is dry on your touch. It requires more water when flowering.

The type of soil you use should contain leaf matter and debris as this is what they feed on. If you want to propagate, do so 2-3 months after flowering.

For them to bloom, they’ll need 12-14 hours of complete darkness daily.

5. Barrel Cactus

Barrel cacti are not just one species but various species belonging to two genera, Ferocactus and Echinocactus. They are native to southwestern North America. Some species reach over 1 meter in height at maturity. Others have been known to reach 3 meters in some areas. They are 30cm wide.

They have a lifespan of an average of 100 years. Naturally, barrel cactus live in extreme heat and direct sun, and it’s only natural to try and mimic the same conditions indoors.

Barrel cacti are muffin-shaped and often pop out over the edges of their pots. You can easily distinguish it because of its elongated fruits and wavy ribs.

The flowers that bloom in April tend to be yellow, orange or purple and are up to 8cm across. The spines can go up to 10cm long. They grow in a circular shape on top of the cactus when it is quite old.

For barrel cactus to bloom, they need full sunlight during spring and summer. Direct sunlight can make them become stunted and sunburned and fail to thrive, which is why they are perfect indoors because you can control the amount of light they are getting.

Due to adapting to arid conditions, their water requirements are not high, and you can even get away with watering every 2-3 months. Unlike other types of cacti, the barrel ones are hard to check for water because their shape almost covers the whole pot and it’s easy to get pricked.

What kills most barrel cacti is overwatering. Only water when you think it’s essential to avoid root rot.

Place your cactus on a south-facing window, and it does best without humidity. You can also add some cactus fertilizer during the growing season. Propagation is by seed.

6. Old Lady Cactus

A Old Lady Cactus. — **Old Lady Cactus**

Old Lady Cactus, commonly known as Mammillaria hahniana, is a powder puff species which grows in arid areas. It is native to central Mexico. It is capable of growing 10inches/25cm by 20inches/50cm broad. The width being 12cm. White spines usually cover it.

The Old Lady Cactus is quite popular. As much as it is found in arid areas, it makes a perfect indoor plant as well. You just need to place it in a sunny place in the brightest spot in the room and avoid overwatering it. A south-facing window is perfect.

It blooms in spring and summer producing red or purple flowers with them being about 0.6 inches/15mm in diameter. It needs 4-6 hours daily for it to thrive.

Make sure when choosing a cactus soil, you get a porous one, one that drains quickly to avoid the roots sitting in water for an extended period. Make sure you add perlite into the mix. You can use potassium fertilizer once during summer.

Only water when the soil is almost dry. It could be weekly or biweekly depending on its requirements. Avoid watering during winter unless the plant needs it.

If you want to propagate, use the offsets that often form clusters on the base of the main plant. Remove the offset and let it dry in a few days so that it forms a callous. Once it forms, you can plant it in a new pot.

7. Bishop’s Cap

Also known as bishop’s hat or bishop’s miter cactus, this particular species is native to the highlands of northeastern and central Mexico.

Its scientific name is Astrophytum myriostigma. The word astrophytum is Greek meaning star plant. Physically, it has about three to seven vertical ribs which define its star-like shape when young. As it matures, the ribs may increase in number and become more cylindrical.

This particular species comes in numerous varieties. What’s frequently found is the mutant of cultivated ones where the colors are only viable if they are grafted because they don’t assimilate because of lack of chlorophyll. In most nurseries, it’s grafted onto another green cactus that has chlorophyll. The plants reach both a heigh and a diameter of 3-5cm while the flowers are 4-5cm wide.

This type of cactus does not require a lot of water. Only water it when the soil feels dry. Don’t water during winter unless it’s a young moon cactus but even on these occasions, water minimally.

For sunlight, they thrive best in bright but avoid direct sunlight. It; s great for beginners as it is a low maintenance cactus.

Outdoor Cactus

1. Prickly Pear Cactus

A Prickly Pear Cactus — **Prickly Pear Cactus**

The Prickly Pear Cactus is also known as Opuntia. The prickly pears (fruits) are referred to as Tuna, and the pads are Nopals.

The cactus can grow to a height of about 5-7m, which is equivalent to 16-23ft with spines of 2.5cm. Some are spineless as well.

The pads are also edible; they require thorough cleaning before incorporating them into your meals. The nopales are used in numerous Mexican dishes such as eggs and salads.

When it comes to propagating, you only need the stem segment. Make sure you plant in spring or summer for better results.

When caring for your cactus, it doesn’t need pruning. Make sure to get the right potting mix with porous soil that drains quickly to avoid water resting in for long. For newly propagated pads, don’t water for the first month. After that, you can water every 2-4 weeks.

Growth may be slow after propagating and may take 3-4 years before it produces many flowers.

As mentioned, the pads are edible — harvest about ⅓ of the pads to keep your plant healthy. The pads are best cut in the mid-morning since the acid content is usually low.

Place the Opuntia where light is maximum as it requires ample sunlight. For hotter climates, have a partial shade for them to avoid scorching. If you plant them outside in garden soil, no fertilizer is needed.

These cacti bloom mid-spring all the way to mid-summer.
