Moon cactus is one of the most recognizable indoor cacti, thanks to its unique shape and a variety of colors that range from yellow to pink, red and orange. These bright neon colors are usually noted in its ball-shaped appearance. They would usually be sitting on top of another green colored typed of cacti.
The moon cactus is a product of human design as the cactus on its own cannot thrive. As such, it needs to be grafted on another green cactus to help offer chlorophyll to make its food. This makes it two plants in one. The beautifully, brightly colored part of the moon cactus cannot produce chlorophyll independently, thus the need to graft it onto another plant.
Moon Cactus is characterized by a ball-shaped appearance and bright colors, including red, pink, yellow, and orange.
Moon cactus is an ideal indoor cacti, especially to the first-timers in horticulture because it’s low on maintenance. They can be used to add some pomp and color to your window seal, living room or porch area. For best results, moon cactus should be positioned in a bright area but away from direct sunlight.

2. Bunny Ear cactus
The bunny ear cactus is a small desert plant that perfectly fits the indoor environment. It is native to Mexico but can be found in most arid and semi-arid areas. It is one of the most popular indoor plants thanks to its unique appearance with pads that mimic rabbit ears. Growing the bunny ears as an indoor plant is simple; all you have to do is ensure the growing conditions are as close to its natural habitat as possible. So with some dry, sunny and low humidity conditions, you can easily grow the bunny ears as an indoor plant.

3. Rat Tail Cactus
The rat tail cactus is an exciting plant native to Central America and southwestern Mexico. It stands out with its long, trailing steps that mimic a rat’s tail, thus its nickname. These stems grow to a maximum of 4 feet. When grown indoors, the rat rail cactus will thrive best when grown in hanging baskets or pots. This enables its trailing stems to get enough space to manifest in its natural growth sequence.
Rat rain cactus comes in many varieties and will bloom in spring and early summer with violet-red blooms. Depending on the variety, however, it can sometimes produce orange and pink-colored flowers. The flowers are fairly large and tubular but will only last a couple of days. Rat rail cactus can be propagated using its stems that grow rapidly under the right conditions. However, you will need to be careful when handling its stems as it grows spines that can prick your skin easily.
4. Old Lady Cactus
The Old Lady cactus, otherwise known as Mammallaria Hahniana is a popular, sun-loving powder puff cactus that can be grown indoors. It stands out with its lone spherical stems that can grow to about 4 inches tall and 8 inches wide. When grown indoors, the cactus should be positioned in a sunny area for better development. If this is not possible, provide some outdoor time during the summer months.
Old Lady Cactus is a small indoor plant that should be placed in a spot with sufficient sunlight.
The best spots to position your Old lady cactus indoors would be by the window as these spots tend to receive enough sun or light for most of the day. However, in cases where you cannot find the best spot with enough light, you may consider using grow lights to help supplement the lighting needs for your cactus.
The Old lady cactus gets its nickname from its white, thin and flexible hairs that may grow as long as 5 centimeters. As the plant reaches maturity, these hairs grow richer and thicker and tend to curl, thus cloaking the plant.
5. Christmas Cactus
The Christmas cactus (Schlumbergera bridgessii) otherwise known as the Easter or Thanksgiving cactus is an interesting plant that blooms just in time for the holidays, thus its name. Its propagation and care are pretty simple, making it a favorite for holiday gift-giving.
Christmas Cactus is an indoor plant that produces reddish pink flowers when grown away from too much sunlight.
The cactus can be propagated from cuttings and will thrive better under moderate indoor conditions. However, Christmas cactus should be kept away from too much sunlight to avoid its leaves getting burnt. Notably, the Christmas cactus blooms with bright colors, but dramatic temperature swings and lack of enough water may cause flower buds to drop prematurely.
To help maximize its blooming period, ensure that you maintain optimal temperatures of about 65 degrees and always keep the soil moist during the blooming period. It is also a good idea to apply for high potassium fertilizer once every two weeks and report yearly after every flowering period.
6. Star Cactus
The Star Cactus (Astrophytum asteria) is one of the few spineless cacti and stands out with its chubby round body that mimics a sand dollar. The fact that it is also easy to grow makes it a perfect candidate for an indoor plant. Its round body may grow to about 6 inches wide. It features some gently ridged sides and covered with some tiny white dots.

These plants do well in average room temperatures and can still survive without exposure to lots of sunlight. Most of them are also flowering species and may surprise you with vibrant blooms, which is a bonus for plants that already thrill with their magnificent shapes and spiny textures.
In this post, we discuss these cacti species in detail and provide you with great insights into how to achieve better results. Keep in mind that growing these succulents indoors is quite different from growing them outdoors. So, let us get started.
Saguaro Cactus
If you have ever visited the Sonoran Desert, you may never forget the astonishing sight of a 40-feet giant Saguaro cactus standing tall in the landscape. The Saguaro cactus (Carnegiea Gigantean) is an enormous and slow-growing plant that can live for up to 200 years.
Saguaro Cactus requires well-drained soil and relatively hot environment to grow healthy.
Its scientific name translates to “gigantic candle” because of its large size. Saguaros are barrel-shaped with external water-storing pleats.
The plant can be used as a source of food for both humans and wild animals and provides a cavity-nesting for various birds. Saguaro plants also have peripheral stems known as arms.
An adult Saguaro can weigh up to six tons or more when filled with water and requires a relatively strong internal support skeleton.
Growing Saguaro Cactus Indoors
Saguaro cactus can only thrive in well-drained soil that doesn’t hold for too long. The plant does well when it receives low levels of water and prolonged exposure to light.
Since it is used to growing in relatively hot conditions, this plant won’t survive freezing temperatures. Make sure you bring your containerized plants indoors as soon as temperatures fall below 60oF.
Water your plant at least once every 10 to 14 days and ensure the soil dries out completely between watering sessions. Check the soil to four inches deep with your fingers just to be sure that it is completely dry.
If you feel even the slightest moisture, wait for a few more days before watering. During winter, stop watering until temperatures start rising above 60oF.
Keep your plant in a brightly lit spot but maintain low humidity. Consider taking your Saguaro outdoors during spring and summer so that it can enjoy the sunlight. Consider keeping it out for several hours a day then bring it back indoors during the night.
Saguaro Cactus Blossoms
This plant is slow to develop and maybe 35 years old or even more before it starts flowering. It mostly blooms in May to June and produces creamy white flowers that are approximately three inches across. Saguaro flowers open up at night and close during the day.
Christmas Cactus
TheSchlumbergera Bridgessii, commonly referred to as the Christmas Cactus, is one of the few spineless cacti species native to Brazilian tropical rainforests. The plant is characterized by its serrated green leaves and beautiful flowers.
Christmas Cactus can grow healthy in low-light conditions with well-draining soil.
The Christmas Cactus does well indoors in relatively moderate home conditions. The secret to getting the best out of your holiday cactus is to avoid too much watering because it can lead to irreversible root rot.
The plant can adapt to low-light environments and does well in well-draining soil that doesn’t hold water for too long. To achieve better results, make sure you use quality potting mix rich in humus and other vital nutrients.
Maintain your indoor temperature at 65oF and keep your soil evenly moist when the plant is flowering. During summer, move it away from the brightly lit spots into more shaded areas.
Christmas Cactus Bloom
The plant starts flowering in winter just around the Christmas period hence the name Christmas Cactus. To start blooming, the plant requires exposure to extended hours of darkness at least four weeks before the flowering season kicks in.
Therefore, it is crucial to relocate your Christmas Cactus to a dark spot in early October and keep it covered for at least 12 hours. This reminds the plant that the blooming season is around the corner, and it should start preparing to form flower buds.
When flower buds start to appear, introduce it to warmer temperatures, and resume regular watering regimen. Fertilize your plant after the flowering season.
Old Lady Cactus
TheMammillaria Hahniana, also known as the Old Lady Cactus, is characterized by white hair that covers its entire surface. This cactus is from the Cactaceae family and is native to Guanajuato State of Mexico and the dry regions of Bolivia and Argentina.
The Old Lady Cactus can still do well indoors if positioned in a room with moderate sunlight exposure.
The white hairs on its surface give the impression of an old lady’s white hair or old man’s beard. The hairs protect the plant from excessive heat and also hide the numerous amounts of yellow spines.
Growing the Old Lady Cactus Indoors
While it thrives well in an outdoor setting, the Old Lady Cactus can still do well indoors if positioned in a room with moderate sunlight exposure.
Plant the Old Lady Cactus in a fast-draining potting mix, preferably with added perlite or pumice for enhanced draining. If you are planting it in a pot, choose a container with plenty of drainage holes.
Although this plant is well-adapted to sustain excessive amounts of heat, do not be deceived because overexposure to direct sunlight can lead to severe and irreversible sunburns. Move it around in the course of the day if you are keeping it in a spot that is lit all day.
You should only water this cactus when the soil is completely dry because it only requires little water to thrive. Be careful not to overwater the plant because it can easily develop irreversible root rot.
During winter, cut back on watering because the plant is dormant and doesn’t require as much water as usual. You can stop watering altogether or only mist it once in a while.
Fertilize your Old Lady Cactus at least once in the summer with a high potassium fertilizer and consider repotting it at least once every year. Repotting should only be done during spring or early summer.
Opuntia Cactus
The prickly pear (Opuntia spp.) is one of the most popular plants in the Cactaceae family. It thrives in drought-prone areas, but it also does well indoors. The plant is characterized by flat and club-shaped pads containing many spines, hence the name prickly pear.
Prickly pear is a fruit-bearing cactus that can thrive in a well-lit place and fast-draining soil.
Most Opuntia cacti species are prized for their edible fruits commonly enjoyed as a refreshing snack in parts of Mexico and the United States. The plant blooms mid-summer, producing lovely yellow, purple and red flowers.
Growing Opuntia Cactus Indoors
As a desert cactus, the prickly pear requires maximum exposure to sunlight/artificial light to survive and thrive. Therefore, consider positioning it in a well-lit spot of your house that receives plenty of sunlight. A north-facing window works best if you live in the southern hemisphere.
However, these plants require little water to thrive. So, limit your watering to once every three or four weeks and only water when the soil is completely dry. The most critical requirement for any plant in the Opuntia genus is a potting mix that drains fast.
Choose a potting mix that is well formulated to drain fast, and when watering your plant, simply moisten; don’t soak. If you are growing your Opuntia spp. in a pot, make sure it contains plenty of drainage holes.
Repot only when the plant outgrows its current pot and make sure you go for the right pot size. It shouldn’t be too small or too big. Fertilize your plant twice every year to ensure healthy and quality blooms. Fertilization should be done in spring.
Barrel Cactus
This cactus is named after its barrel/circular shape. The plant is also nicknamed the “Mother-in-law-cushion” and is mostly found in Mexico and parts of Southwestern US. In their natural habitat, these plants live in extremely hot areas and have adapted to direct sunlight.
Barrel cactus can grow in relatively low temperatures but cannot tolerate humidity.
They make perfect display plants when grown indoors since they are highly attractive. As they grow, they tend to stretch out and assume a circular or oval shape. Just like other cacti plants, the secret to growing them indoors successfully is perfect drainage.
Growing Barrel Cactus Indoors
Barrel cactus does best in relatively sunny spots. Therefore, consider positioning it on a north-facing window. If your house doesn’t have a perfect place that receives plenty of sunlight, install artificial growth lights.
The plant can tolerate low temperatures of up to 50oF but does best without humidity. As long as everything is kept constant, the plant should be fine in a regular household environment.
Make sure you use a well-draining potting mix and repot the plant as soon as the soil starts to break down. You can encourage drainage by adding sand or extra perlite to the soil or adding a few inches of small pebbles or gravel to the bottom of the container.
Feed your barrel cactus with a weak liquid fertilizer solution at least once during spring. Water infrequently and ensure that the potting mix drains out completely during watering. Do not allow the plant to sit in water because the results can be catastrophic.
How Long Can a Cactus Survive Indoors?
Cactus plants are well-suited for indoor living since they require little maintenance. With proper care, cacti can survive indoors for several years and even decades.
Ensure you provide adequate light, the right soil mix, and enough water to help them thrive indoors. Also, remember not to overwater since too much water can lead to root rot.
Lastly, ensure you repot your cacti when needed and fertilize them twice a year. Typically, you should repot your indoor cacti every two or three years and fertilize them once in spring.
When repotting, pay close attention to the soil mix you use since this will determine how well your cacti survive indoors. A good quality potting mix that drains fast is essential for their healthy growth and survival.
Also, go for a pot slightly bigger than your existing one to provide enough space for the roots and top growth. Ideally, the new pot should be two to three inches larger than the previous one.
For instance, if the current pot is five inches in diameter, go for one that is seven to eight inches in diameter. This will give your cactus plenty of room to grow.
Can an Indoor Cactus Flower?
Yes, an indoor cactus can flower. While some cacti species may remain vegetative for years, others will produce flowers under the right conditions.
Typically, these plants need plenty of light and a warm temperature to flower successfully indoors.
You must also remember to feed your cactus regularly during spring and summer to ensure healthy and quality blooms.
Consider using a balanced liquid fertilizer that is formulated for cacti and succulents. Use the solution at half strength and apply it every other month during the growing season.
How Often Should I Prune My Indoor Cactus?
It is normal for your indoor cactus to outgrow its pot and become bushy. As this happens, it will require regular pruning. Pruning helps encourage healthy growth and enhances the appearance of the plant.
To ensure vigorous growth, you should prune any overgrown parts of the cactus during springtime or summer. Use sharp pruning shears or scissors to avoid damage and cut the stems off at their base.
How Do I Treat Pests and Diseases On My Indoor Cactus?
Indoor cacti may be affected by pests and diseases, especially if they are overwatered or exposed to low temperatures. Common pest infestations include spider mites, mealybugs, aphids, and scale insects.
To treat these pests, you can use insecticidal soap or neem oil to eliminate them. Consider using a systemic insecticide formulated for cacti and succulents if the infestation is severe.
If your plant shows signs of fungal or bacterial diseases, consider discarding it because the diseases can quickly spread to other plants in your collection.
Summary

The fame and reputation Bagua quadrant corner corresponds to the fire element, and colors present in this section should be bright and fiery such as red, yellow, or orange.
In this post, we discuss everything you need to know about good Feng Shui and cacti plants. We shall help you understand what Feng Shui is all about and how you can use the practice to arrange your cacti plants to bring good vibes to your indoors.
So, let us get started.
The Basic Principles of Feng Shui: A Quick Overview
Feng Shui is a Chinese term used to refer to the practice of looking at our living spaces and working environment and finding a way of striking balance with the natural world. The two words translate to “wind” and “water,” respectively.
The concept was derived from an ancient poem that talks about our lives flowing with and being connected to the environment around it. The basic principles of Feng Shui are; the commanding position, the Bagua, and the five elements.
1. The commanding position
This refers to the spot in a room that is furthest from the entrance and not in direct line with it. Basically, the commanding position practice puts you diagonal to the door when you are sitting at this spot. However, it maintains a clear line of sight with the door.
The commanding position practice puts you diagonal to the door when you are sitting at this spot.
Ideally, this is where you should be spending most of your time. Feng Shui principles suggest that you determine this spot in your favorite room then place your stove, desk, or bed in a diagonal alignment if possible.
The three items are important because they represent essential parts of your life. The bed represents you (who you are), the stove represents your health and nourishment, and the desk acts as an extension of your career.
2. The Bagua Map
A Bagua is a term used in Feng Shui to mean an energy map that is superimposed on the floor plan of your house. The word “Bagua” translates to “eight areas.” According to Feng Shui principles, each of the eight areas on the map represent a different life circumstance such as career, wealth, or family.
Each of the eight areas corresponds to different shapes, colors, seasons, earthly elements, and numbers. At the center of this map is a ninth element that represents your overall health and wellness. The element is, you.
3. The five elements
Metal, water, fire, wood, and earth are the elements of Feng Shui, which represent different phases of the life.
The five elements of Feng Shui are metal, water, fire, wood, and earth. These elements represent five interrelated phases in your life that work together to create a complete system.
Feng Shui works to create a balance between the five elements and integrate them into different areas of your life.
To integrate the five elements in your home and life, you must decide where you want to focus your energy.
From the commanding position, you can only choose one area of your life that you want to improve, and then you strengthen your energy in that area by adding specific colors and shapes. You can read more about Feng Shui here.
What Is Wrong with Cacti Plants?
The presence of spines all around the cacti bodies generates negative energy.
Now that you understand the basic principles of Feng Shui let us evaluate why you need to be careful with these succulents when growing them indoors.
Generally, plants bring positive Feng Shui to your home. However, cacti plants are quite different, and you have to place them in specific spots to enjoy positive energy. We do not deny the fact that these are nice plants that emit strong protective energy.
However, the biggest problem is their spines/needles. Since their spines are tiny and look like hundreds of arrows, they tend to shoot negative energy into the surrounding space.
This is the primary reason why you need to choose a good placement for your cacti plants, according to Feng Shui. Cacti plants can bring bad vibes if you place them in the wrong area.
Areas Where You Shouldn’t Put a cactus Plant in Your Home
You should avoid putting your cacti in the living room, kitchen, bathroom, and bedroom.
If you suddenly get itchy, irritable, or nervous after you have just purchased a cactus plant and placed it in your indoor areas, then you should conduct quick research to find out what is disturbing you. It might be the plant that you have just brought in.
Typically, cacti plants shouldn’t be placed in the following areas of your home:
1. Living room
A living room is a place that should have good Feng Shui. It should be calm and secluded from the other areas of your house because this is where you come when you want to feel comfort and peace.
If you have cacti plants all over the place, they will continuously poke you with their pointed spines, making you feel uncomfortable. Therefore, unless the fame and reputation Bagua quadrant is in your living room, do not put cacti plants there.
2. Kitchen
A kitchen is a place where you prepare meals and drinks for your family or guests, and you don’t want your food to taste awkward.
Positioning a cactus plant in the kitchen area might spoil the taste of your food because the plant’s spines produce negative energy, which could be transferred to the food you are preparing and eventually to the people eating the food.
3. Bathroom
Bathrooms are also not a good place to put cacti plants because when you are there, you need peace of mind. However, there is one exception. If you want to convert your bathroom to your fame and reputation quadrant, then you can position your cactus plant there.
4. Bedroom
Your bedroom is probably the only place you find comfort and peace while you sleep. Therefore, you wouldn’t want any negative energy to disturb your peace and sleep after a long day at work. If you place cacti plants in your bedroom, you may get pricked now and then.
5. Areas close to the entrance or outside your main door
Don’t place your cacti plants close to the main door unless you have annoying neighbors that you want to keep away. If that is not the case, you want the area around the main door to be free to allow new and refreshing energy to stream into your house.
6. Office desk
Placing a cactus plant on your office desk is also a bad idea because it can chase away potential customers and business partners. You want to keep your working space as tidy as possible and free from negative energy.
So, Where Should You Place Your Cactus to Ensure Good Feng Shui
Putting your cactus in the fame and reputation Bagua quadrantwill generate good Feng Shui.
If you have read this article up to this point, I’m sure you already know where to place your cactus to ensure good Feng Shui. Don’t worry if you skipped directly to this section because we shall explain everything in detail.
Generally, if you want to bring good Feng Shui to your home, you need to make sure that your cacti plants go into the fame and reputation Bagua quadrant.
The fame and reputation Bagua quadrant is part of your house that is dedicated to your personality and what you desire to show to the outside world. The section is usually located in the far back corner of the middle portion of your living space.
As mentioned earlier, there are nine quadrants on the Bagua map. The ninth section of the map is dedicated to you and your reputation. It defines what you and what you want to contribute to the outside world.
The main element of this quadrant is fire. You can use any fire symbol, including a bright red color, to bring good Feng Shui to this section. Orange and yellow are also acceptable.
The fame corner is always the right place to place any personal achievements such as medals, trophies, awards, degree certificates, and so on. This is also the right place to install a fireplace.
Additionally, you can position your cacti plants on windows to keep away enemies. When positioned on windows, these plants will work towards protecting your home, career, and reputation.
Final Thoughts
Cacti plants are good indoor plants but where you position them in the house matters. The safest position for a cactus plant in your home is the fame and reputation Bagua quadrant that represents your personality and what you desire to show to the outside world.
Make sure your cacti plants are not positioned in your living room, bathroom, kitchen, bedroom, or close to the main door. Otherwise, these succulents may affect your life in ways you didn’t expect.

It’s hard to ignore the beauty of a moon cactus. These impressive cacti grow anywhere from one to eight inches in height. What makes them unique is that they take a lot of effort to seed, graft, and cultivate due to a novel mutation. Thankfully, growing them once they have sprouted is a cinch.
With their bright pink, orange, or yellow tops, moon cacti must be specially cultivated due to their inability to produce chlorophyll. Store-bought cacti are already made grafted and ready to produce chlorophyll, which is why they are your best option.
Moon cacti are one of the rare types of cacti that work well with shade. Too much sun can and will scorch them. Though they do not need too much sunlight, they will need a little heat. Temperatures as lower than 48 degrees will hurt them.
Easter Cactus – Best for Flower Lovers
Easter Cactus features bright red lotus-like blossoms during April and May.
Most cacti flower, but rarely enough that it’s a big deal when they do. This is not the case with Easter Cacti, which are known for their bright, beautiful, lotus-like flowers that shoot right out of its green stem. They have so many flowers that you would be forgiven if you mistook them for a regular flowerbed plant!
The thing about Easter Cacti you should be aware of is that they only flower two months in the year—April and May. However, they’re perennial and will bloom again and again. When cared for properly, you can expect these cacti to grow to a size of one square foot. That makes them great plants for smaller homes.
Considering their top blooming season, it’s unsurprising that they like warm-ish temperatures. Do not put them in direct sunlight, though, since the harsh sun can easily wilt those tender flowers. A better option would be to put them in bright, yet indirect natural sun—-much like what you would get from light through sheer curtains.
Ladyfinger Cactus – Best for Windowsills
With its petite “towers” of spiny greenery, it’s easy to see where the nickname of “ladyfinger” came from. They bear a remarkable similarity to the sandwich cookies. Unlike those popular cookies, these cacti bear pretty little flowers that will bring a splash of color to any home.
People looking for a small cactus that thrives in sun to partial shade are going to love the small, cute, and easy to care for fun that ladyfingers offer. This cactus requires minimal water during the summer. When it goes dormant in winter, you might not need to water it at all.
This cactus has strikingly similar needs to succulents, especially when you consider the low maintenance requirements. That makes it a great starter plant for people who just want a little windowsill beauty.
Dwarf Chin Cactus – Best for Heavy Shade
If there is one thing that this list proves, it’s that cacti rarely ever are just all green towers of spines. They have the propensity to have flowers and fruit that add serious color that can rival any rose, tulip, or peony. The Dwarf Chin Cactus is an excellent example of this in action.
Though these spiny cacti will only grow to a maximum of six inches, they pack a serious punch of beauty. When they are in full bloom, these cacti produce flowers that come in a wide range of colors—brilliant red, sunny yellow, rich salmon, and hot pink, just to name a few.
Surprisingly, these cacti do best in heavy shade. So, if you thought that you needed to have brightly lit areas to have a cactus inside your home, you’re wrong. The Dwarf Chin Cactus is a perfect pick for your indoor garden.
Christmas Cactus – Best for Wintery Cheer
Christmas Cactus requires nutrient-rich soil to blossom in the middle of winter, usually in December.
The Christmas Cactus doesn’t get its name for its orange blooms atop its green spine. Rather, it gets its nickname from its tendency to bloom in the middle of winter, mostly in the middle of December. The stalks of these cacti droop over pots and have leaf-like folds, giving them a unique shape that raises eyebrows.
If you decided to go indoor gardening during the winter, this might be one of the few cacti you will see for sale. They are regularly offered up as Christmas centerpieces, particularly in the American Southwest. Finding them during other times of the year can prove to be a little tricky.
This cactus is unusual in that it needs a lot of lush, nutrient-rich soil to thrive. Aside from that, doing the routine of minimal water and moderate sunlight is all you need to make them happy.
Saguaro Cactus – Best for Traditionalists
When most people think of a cactus, they are thinking of a Saguaro cactus. These cacti are the tall, spiny plants that are typically tower above people when they’re left to grow out in the United States. Their reputation for being extremely tall often dissuades people from having them, but don’t dismiss them quite yet.
Saguaro cacti are known for being huge, but they start off incredibly petite. They also are notoriously slow growers, so the fear of having your cactus poke holes in your ceiling is unfounded. If you love petite cacti, you will love how cute Saguaros can be when they are young and placed in a small pot.
If you choose to get a Saguaro, you might need to be a little more involved than a typical cactus owner. You will need to house it in draining grit and give it minimal water. Lots of sun and warm weather are a must-have for these gentle giants.
Believe it or not, Saguaro cacti can blossom. However, chances are you will not see them bloom since it can take up to 35 years or more before a single blossom can happen.
Queen of the Night Cactus – Best for Night Owls
Queen of the Night Cactus displays its mesmerizing pearly white to pinkish blooms during nighttime.
Cacti typically bloom in the daytime, but not this one. The Queen of the Night only will display its gorgeous flowers during nighttime. Despite the gothic name, the flowers on this home-friendly cactus are a beautiful, almost pearly white.
Like Saguaros, the Queen of the Night is a cactus species that has a reputation for being a tall grower—and rightfully so. These perennials can grow up to a whopping 10 feet tall if they are given enough space and time. These plants love shady areas that mimic the darkness of jungle floors.
When adding soil, make sure that your cactus gets a nice amount of ventilation. If you want then to bloom, make sure to add fertilizer to their soil once during the spring. These cacti are slow growers, so don’t be disappointed if they do not seem to noticeably grow.
Picking the Right Cacti for You
Every cactus is a little different in terms of maintenance, biological needs, and appearance. Some cacti are known for being a little on the plain side, while others are celebrated for their vibrant flowers. Some, such as the Barbary Fig, are noted for their edible fruits.
You cannot treat cacti like a “one size fits all” matter. If you want to choose a good cactus for your lifestyle, it’s important to consider these factors:
Sunlight. Most cacti require bright, direct sunlight. If you live in a shady area, this limits the number of cacti you can grow. You might be better off with a Queen of the Night, or a Moon Cactus in those cases.
Free Space. Cacti vary greatly in size. Some can be as tiny as an inch high. Others can grow up to dozens of feet tall. If you have limited space, it’s important to choose a cactus that “maxes out” at a small size or that grows exceptionally slowly.
Temperature. Though some cacti can survive in temperatures as low as 10 degrees Fahrenheit, most require a temperature around 50 to 70 degrees to live. Some thrive in even higher daily temperatures, so placing your cactus near a heater might not be a bad idea.
Blooms. Not all cactuses have flowers, though most of them do. If you are focused on aesthetics, then you might want to learn more about how each cactus blooms and what it means for your apartment or home’s look.
Potting.Believe it or not, some cacti have a hard time sharing pots with others. For example, the Saguaros are famous for competing with other plants’ resources and killing them through nutrient draining. Other cacti work well in groups.
Required Maintenance. Cacti might be low maintenance compared to most other types of plant life, but that does not mean they all have virtually no need for help. Some cacti are more demanding than others—especially when it comes to fertilization, water, or sunlight. If you are worried about being tight on time, getting a notably low-maintenance cactus is ideal.
What Are the Best Types of Cacti to Grow Indoors?
The best cacti for newbies all have a couple of traits in common. They are hardy, they require little water, and they are not going to grow too tall too quickly.
Are Cacti Safe to Have Around Pets?
Unlike other plants, cacti are generally not poisonous. This makes them a great choice for people who have pets that like to chew on things or kids who might be a little too curious for their own good. Though they might not be poisonous, they still aren’t for every household.
Some cacti have spines that harbor bacteria on their spikes, which can cause a variety of ailments. You should research the cactus’ toxicity before bringing it indoors if you’re concerned about poisonous plants near your pets or children. While most commercially sold cacti are not poisonous, it’s always better to be safe than sorry.
What Do You Need to Grow Cactus?
Growing cactus is not as demanding as other flowers, like roses or orchids. That’s one of the reasons why they’re appealing to newbie gardeners and why busy homeowners tend to love having them around.
Though they are easy to grow, you still need to get supplies. While the distinct needs of each cactus species can vary, these supplies below are usually advisable:
Clay Pots. Most cacti need to be in clay pots rather than plastic pots. The clay helps wick away excess moisture and keep soil dry.
Cactus Soil. While some cacti can use regular potting soil or a mixture of sand and soil, getting quality soil designed with cacti in mind is usually ideal. If you cannot find cactus soil near you, most cactus types can also make do with potting soil that has small amounts of sand mixed in.
Fertilizer. Though cacti don’t need a lot of nutrients in most cases, a little fertilizer is still necessary. This is doubly true if you want them to bloom.
Gravel. This isn’t required, per se, but a lot of homeowners find that adding a light (or sparse) layer of multicolored gravel can help bring a new level of beauty to a potted cactus or succulent.
Are Cacti Safe to Have Around Kids?
Since cacti are generally prickly (unlike succulents), it’s important to make sure that any cacti you choose to raise will not be near klutzy people or near kids who might get reckless and prick themselves.
Certain age groups are at particular risk of getting pricked or having cactus-related injuries. If you are a parent to a toddler or children under the age of six, it’s best to consider getting plants other than a cactus.
Are There Any Types of Cacti You Should Avoid?
For the most part, commercial growers do not sell cacti that are openly dangerous or unusually high maintenance. If you are new to growing cacti, you should stick to common, mainstream species.
Exotic species are rare to find in households for a reason. They are often species that require extremely specific growing conditions, cannot be sprouted naturally, or are poisonous to the touch. There are also exotic cacti that cannot be grown indoors or transplanted into a different pot. That is usually why stores are hesitant to sell them.
It’s not always easy to know if a cactus is exotic or poisonous. If you are in a specialty store, the best thing you can do is ask some of the staff members to advise you on which cacti are better for indoor gardens or beginners.
Can You Plant Multiple Cacti in One Pot?
The general answer is yes, as long as the cactus types you choose are not known for competing for resources and are given ample space. Many cactus gardeners start out their indoor gardens with larger pots containing multiple types of cacti.
It’s better to stick multiple plants of the same type in a single pot.
If you choose to go this route, make sure to choose cacti that require similar soil types. Otherwise, you might end up causing one plant to suffer due to improper potting. If you want to keep things on the safe side, it’s better to stick multiple plants of the same type in a single pot.
How to Keep Your Cactus Alive During the Winter
Cacti are perennials that are a lot hardier than people make them out to be. The worry about keeping them at high heat is often unfounded since most cacti only need to have an average temperature between 40- and 60-degrees Fahrenheit. Some can go even lower, with a minimum temperature of 20 degrees.
It’s a common misconception that cacti look the same year-round, Many, if not most, cacti go dormant in the winter. If you notice your cactus looking a little wilted or brown, do not panic. Check to see if it’s time for it to go dormant and reduce your watering schedule. With time, it will be able to bloom once more.
Conclusion
When you’re just starting your own indoor garden, getting a cactus seems like an easy way to get a splash of color for minimal effort—and it absolutely can be. When in a house filled with responsible individuals, owning one or more cacti can be a great way to have a low-maintenance indoor garden that makes a serious statement.
Choosing a cactus that is appropriate for your indoor garden isn’t something you should take lightly. While everyone loves Moon Cacti, Barbary Figs, and Saguaros, the space and conditions you have available to you will need to play a deciding factor in which plants you choose to get.
After you choose the right cacti, the rest of your indoor gardening journey is pretty straightforward. All you have to do is follow the care instructions your cactus comes with, and with time, you’ll be able to see beautiful cactus blossoms and enjoy your garden for years to come.
Cacti are unique plants that belong to the family Cactaceae. The family is pretty large and features over 127 genera and 2500 species. These plants thrive both indoors and outdoors and are always an excellent option to add to your plant collection. Indoor cacti plants require little maintenance to thrive and are beneficial in a wide range of ways. But how long do indoor cacti plants live? Let us find out.
How long does an indoor cactus plant live? In the wilderness, these plants can survive for hundreds of years, but things change when they are grown indoors. On average, indoor cacti plants survive for ten years or slightly more. However, with the right growing conditions and ideal care, the lifespan of an indoor cactus plant can be increased significantly.
But, you should know that the lifespan of these succulents depends on a lot of factors. The three main factors that will affect the lifespan of your indoor cactus are species, growth conditions, and care.
In this post, we discuss everything you need to know about the lifespan of indoor cacti plants and what you can do to make sure your spiny friend lives longer. So, let us get started.
The lifespan of a Cactus Plant Indoors: Detailed Discussion
Generally, cacti plants growing in the wilderness tend to live muchlonger than their indoor counterparts. In an ideal setting, an outdoor cactus plant can survive for up to 200 years or more.
However, indoor plants have to adapt to a new environment and new conditions which tend to destabilize the plant. On average, an indoor cactus plant will survive for ten years. Some delicate species will even die after a few months, but that shouldn’t worry you so much.
As long as you are taking good care of your plant and providing it with good growing conditions, you can be sure to have it around for a prolonged time.
Before we dive deep into our discussion, let’s take a few minutes to discuss the general lifespan of some of the famous cacti species.
How long does a Christmas cactus live?
Christmas cactus lives for about 20 to 30 years if proper maintenance is provided.
Let us start with one of the most common types of cacti grown indoors; the Christmas cactus. This beautiful indoor plant belongs to the genusSchlumbergera, and many plant scientists consider it a hybrid between two different cacti species.
Generally, the Christmas cactus closely resembles the Schlumbergera truncate, which is commonly referred to as the Thanksgiving cactus.
Its name is derived from its unique characteristic of blooming in the winter around the Christmas period. The plant is native to the tropical rainforests of Brazil and tends to grow better in relatively cool temperatures.
The average lifespan of a Christmas cactus is approximately 20 to 30 years, but a lot depends on the care and maintenance you provide.
Proper care, in this case, includes providing a relatively cool and humid environment, frequent watering, and a moderately sunny location.
However, you need to be careful not to overwater your plant because it can cause severe and irreversible damage.
How long does a Saguaro cactus live
Saguaro is a type of gigantic cactus with the height of over 50 feet. The cactus can last for up to 200 years.
Another famous cactus plant is the Saguaro that is native to North America. The plant belongs to theCarnegiea genus and gigantea species. The Saguaro is a slow-growing plant, but it is gigantic. In fact, a fully grown Saguaro can reach a height of up to 50 or 60 feet.
One thing that is unique about this cactus is that young Saguaro plants cannot live independently. In most cases, there will be an adult Saguaro nursing and protecting a baby Saguaro until a certain age.
Sometimes, the older plants die in the process, leaving the younger plants to take up their space.
It is also interesting to note that in its first ten years, a Saguaro plant doesn’t grow more than two inches. Furthermore, it doesn’t start flowering until when it is over 30 years old and the first arm will only start growing when the plant is more than 75 years old.
On average, a saguaro cactus can live for up to 200 years, but that aging will depend on a wide range of factors. The average age of an adult is about 125 years.
If you want to grow this plant in your home, make sure you grow it outdoors and in the ground to provide it with enough space to stretch out and attain its maximum size.
How long does a Moon cactus live?
The lifespan of gorgeous Moon cactus can range anywhere between a few months to several years.
Moon cacti are also popular houseplants in different parts of the world. The plant has a wide range of different names, such as the Hibotan cactus, Red Cap, and the Ruby Ball plant.
Many people love the Moon Cactus for its attractive appearance that resembles a lollipop. The lower part of the plant carries and supports a round moon-like part that is usually red, yellow, orange, or purple.
Determining the exact lifespan of a moon cactus is sometimes tricky because it is a combination of two different cacti species.
For instance, the Gymnocalycium (one of the parents of the moon cactus) doesn’t grow more than a few inches tall and lacks chlorophyll while the Hylocereus (the other parent plant of moon cactus) grows to a height of up to 30 feet and is evergreen.
You will notice that the two species that come together to form the moon cactus have entirely different characteristics and growth requirements.
Consequently, the moon cactus becomes a unique combination of two different and incompatible cacti species. This means that the plant is relatively weak and unstable. Therefore, it can only survive for a relatively short time before it dies.
Typically, a moon cactus has a shorter lifespan that ranges from months to a few years. Sometimes, it may die within three months or survive for up to a decade.
Proper care and suitable growing conditions can increase the lifespan of the plant quite significantly.
How long does the Golden Barrel cactus live?
The golden barrel cactus is native to the Sonoran Desert in Mexico and Arizona. It gets its name from its unique shape, which looks like a large, round barrel.
This cactus can reach heights of up to 5 feet when fully grown, and its spines are yellow or golden.
The golden barrel cactus is a very hardy and resilient plant, so it can live for quite a long time if given the proper care. It generally has an average lifespan of 30 to 50 years; some species have been known to live for up to 100 years or more.
However, it is essential to note that the golden barrel cactus will not reach its full size until it is around 15 years old.
If you want to keep your golden barrel cactus healthy and long-lived, make sure to provide it with enough sunlight and water. Regular pruning can help the plant stay healthy and free from pests and diseases.
Overall, it is a relatively easy plant to take care of and can provide you with many years of beauty and enjoyment.
How long does the prickly pear cactus live?
Another common indoor cactus plant is the prickly pear cactus, which belongs to the Opuntia genus. It is a low-maintenance plant that thrives in sunny locations and requires minimal watering.
The exact lifespan of a prickly pear cactus will depend mainly on the size of the cactus and its growing conditions. On average, a small prickly pear cactus can live for up to 40 years, whereas a large one may live for more than 200 years.
Good growing conditions and proper care will help to extend the life of the cactus significantly. If you want your prickly pear to last longer, ensure it is exposed to plenty of sunlight and not overwatered.
How To Grow Cactus Indoors for a Longer Lifespan
As long as you follow the instructions you will not have any issues with growing a thriving cactus.
Growing cacti plants indoors is not a difficult thing to do, but you need to ensure you are providing your plant with the right conditions for better results.
Successful gardening of these succulents does require sticking to simple rules and being perfect in doing the small things that matter.
Here are some tips on how to look after your cactus indoors if you want it to live long.
1. Watering
Watering is perhaps the most important thing you need to master if you want to have a cactus plant for longer. Although underwatering is an issue, overwatering is by far the most common cause of death for these succulents.
The trick to getting it right is to follow the plant’s natural seasonal habits. For instance, you should always treat winter as a period of rest for the plant. During this time, you don’t need to water your plant frequently because it is in a state of dormancy. In this case, only water when the potting mix is completely dry.
During spring and summer, you need to water your plant frequently because this is the active growing season. Every time you water, allow the excess water to drain out quickly and let the soil dry slightly between watering.
Potting is another important aspect of indoor cacti plants that you should pay close attention to. When choosing a pot for your plant, make sure it is the right size and weight.Even if you decide to go for a relatively heavier pot for purposes of preventing it from tipping over, you have to get the size right.
The potting mix you use should be fast-draining and full of nutrients for better results. If you cannot make your own potting soil, go for the commercially prepared options, but be sure to check on drainage thoroughly.
When your plant becomes bigger, consider repotting it into a new and bigger container to allow growth without causing root damage. Typically, you should consider repotting your cactus plant once every two years.
3. Position
Lastly, where you position your plant plays a critical role because it determines the amount of sunlight that it receives. Most cacti species love a lot of light and airy spaces, but make sure you are not exposing your plants to extremely bright light because they can suffer sunburns.
Also, after winter, if you want to take your plants out, do so gradually. You can start by positioning them under shades for a few days before you expose them to direct sunlight.
Position your plants close to north-facing windows so that they can receive plenty of sunlight.
If you are living in the southern hemisphere, position your plants close to north-facing windows so that they can receive plenty of sunlight. If you are living in the northern hemisphere, east-facing windows will be a good option.
4. Fertilizing
While many cacti species don’t require regular fertilizing to thrive, it is always a good idea to give them some extra nutrients during the growing season.
Always go for a balanced fertilizer that either has an NPK ratio of 10-10-10 or 6-12-6 and use it in moderation. Fertilizing should be done once every two months, but always reduce the frequency during winter because most cacti species slide into a state of dormancy.
For better results, you can also add some organic matter to the soil, such as compost or worm castings. This will give your cacti the essential nutrients it needs to grow and thrive indoors.
Final Thoughts
Cacti plants come in different colors, structures, and sizes. These plants are unique and good houseplants since they require little maintenance to survive. They are hard, resilient, and live for many years.
Generally, outdoor plants live longer than indoor plants because the indoor environment tends to have a significant impact on the structure and adaptation of the plant. While some indoor cacti can survive for more than ten years, others will die after only a few months.
Fortunately, there are lots of things you can do to increase the lifespan of your indoor plants. Providing an ideal growing environment and proper care can go a long way in increasing the lifespan of your indoor plants.
There are over 1,500 species of cacti, and they make excellent houseplants and lovely additions to your lawn because they are beautiful and easy to maintain. Cacti are one of the world’s most beloved plants to grow indoors and out. This preference is because not only are they beautiful and somewhat mysterious plants, they also enjoy long lifespans.
What is the lifespan of a cacti plant? The lifespan of a cactus typically ranges from between ten to two-hundred years, depending on the species with cacti growing outdoors in optimum conditions living the longest. However, with sufficient care, indoor cacti can live for many decades.
Read on to discover how long common cacti live and methods to keep them alive to give you years of pleasure.
Commonly Grown Outdoor Cacti & Their Lifespan
As stated, there are over fifteen-hundred species of cactus, with some having longer lifespans than others. Cacti are native throughout most of North and South America in arid areas, such as Arizona or New Mexico.
The longest living cactus is thought to have been the Saguaro cacti that can grow up to sixty or seventy feet in height and live for 150 to 200 years. In fact, one Saguaro cacti that lived in Arizona was thought to be three-hundred years old and died of a bacterial infection caused by an injury in the 1990s.
Some of the types of outdoor cacti, which require specific care to improve their health and increase the lifespan
Barrel cacti, also known as the mother-in-law cushion, are a preferred plant for indoors and outdoors growing wild in arid communities in the southwestern United States. A barrel cactus do not live quite as long as the Saguaro with a lifespan of 50 to 100 years. However, some have lived for up to 130 years.
Prickly Pear cacti, a favorite plant for lizards and other wildlife in the southwestern United States, after two or three years, yields as many as 200 fruits in the growing season. The fruit of the Prickly Pear plant can also be consumed by humans and taste sweet. These plants do not live as long as the other two cacti above, living only twenty to thirty years.
Commonly Grown Indoor Cacti & Their Lifespan
Indoor cacti, which can live for many years in the case of proper care and well maintenance
Indoor succulent cacti such as Acanthocalycium Thionanthum with its large yellow flowers and Aloe Vera often grown indoors for its medicinal purposes. When well-maintained, these cactus plants can live in your home for many years. Some of these include:
Bunny Ears Cactus
Old Lady Cactus
Star Cactus
Easter Cactus
How to Ensure a Long Life for Your Cactus
Because of the artificial environment of the indoors, cacti are entirely at your mercy. Although cacti are not difficult to care for, there are some urgent things to remember to ensure your plant lives for years.
The most vital factor is to read up on your cactus species’ light, heat, drainage, soil, and water requirements. Different species have varied needs; however, there are some general methods you can employ to keep your cacti alive.
Watering
Cacti need regular watering and proper drainage just like any other plant. Water your cacti deeply throughout the hottest months but do not waterlog the roots. Prevent overwatering or dampness by having drainage holes in your pot. During colder months, your cactus will not require as much water. Watering your cactus in cold weather can damage or kill your plant because the water inside your cactus will freeze.
You should always keep your indoor and outdoor cacti hydrated but never overwater them!
Light
Cacti love sunlight. They are built for the hot desert sun, and whether living indoors or out must remain in the brightest spot in your yard or house. This is especially vital during the cold winter months. However, you should monitor the stems of your indoor plants to make sure they are not being burned by too much sunlight being amplified through the window.
Sunlight is very important for both indoor and outdoor cacti, especially during cold months
Soil Type
The correct soil is the same whether your plant is indoors or out: a sandy, coarse soil that does not remain damp after watering or a rainstorm. To achieve this type of soil, mix a specialized mix made for succulents or combine sand, perlite, and potting soil. Succulent and cactus soil is found at home, your local gardening center, or home improvement shop.
Heat
The best climate to keep your cacti is between 40 to 90 degrees Fahrenheit (4 and 32 degrees Celsius). Cacti can live for short periods in colder temperatures. Still, if the temperature drops below 35 F. (2 C.), it is time to move your plant. If cold weather is predicted in your area overnight in a desert climate, do not worry. Your plant can live through a cold night or two.
If the temperature drops below 35 F. (2 C.), it is time to move your plant.
Problems Your Cactus Might Exhibit While Aging
Because cacti live lengthy lives, as they begin to age, any blemishes or damages they pick up over time will stay with them for the rest of their lives. Even things such as too much direct sunlight will scorch your cacti. This can lead to damage to the surface of the plant. Although blemishes may seem cosmetic, injuries will cause your plant to be unhealthy and shorten its lifespan.
Different species of cacti react differently as they age to damage and sickness, and it is believed that genetic factors play a considerable part. Even with excellent care, your cacti will eventually fall prey to its own genetic makeup.
A prime method to know your cactus is aging is to see it lose its arms or stalks to the ground. However, as a cacti ages, losing stalks play a vital role in reproduction as they can become rooted and grow into a new plant.
Special Adaptations that Allow Cacti to Live So Long
Cacti have particular adaptations that allow them to live long and healthy lives in the most inhospitable regions, like hot, dry deserts, on earth. These include:
Cacti do not have leaves or branches. Leaves and branches allow a large amount of water loss because of their large surface area. Cacti spines also have a large surface area, but they contain almost no water, instead, they are made of fiber.
Cacti spread their roots shallow and wide in the soil so that when it does rain, they can collect water from wide-area and absorb as much as they can.
Cacti have a central stem composed of a thick and fleshy consistency with a waxy waterproof coating. This adaptation allows the cactus to store copious amounts of water in the succulent stem and not risk any water loss. Cacti can expand and reduce the size of their stem as the water level within it changes.
Cacti have spines to protect them from animals eating them and explains why cacti have so few predators.
Cacti rapidly develop fine root hairs after a rainfall to maximize the water they can absorb for the short time the water is available in the desert. Once the ground dries, the roots no longer need their fine hairs and will die.
Obviously, the cactus in your living room or front yard is more complicated than you ever imagined and is made for survival. However, with the right care, cacti can live for decades and even hundreds of years. Taking care of your cacti, whether it is an outdoor plant or indoor, will lead to a long and happy relationship with these enigmatic and beautiful plants.
Cacti plants are an exceptionally resilient group of plants, and just as much as they are resilient, they are diverse! Usually recognized for their ability to sustain life on little water and in harsh desert environments, you may be surprised what other conditions some cacti can thrive in.
Which cactus is best to grow indoor with low light? The answer is not just one cactus, but quite a few varieties can live and grow in dim, partial, or indirect light, including the scarlet ball cactus, crown cactus, zebra cactus, and Christmas cactus.
While everyone is most familiar with the cacti that thrive in blindly bright, scorching hot desert environments, other varieties survive quite well in different conditions. You may be pleasantly surprised by how many options of cacti you have if you are looking to spruce up your apartment, office space, or any other dimly lit room.
This article will go over the four best cacti to grow indoor and in spaces with low or limited light.
4 of the Best Types of Cacti for Indoor with Low Light:
1. Scarlet Ball Cactus (Parodia Haselbergii)
This cactus is a small, round looking cactus with many fine, straight spines. They may bloom red or yellow flowers on the crown of the plant. These cacti are recognized as an easy to care for variety and are great as a starter for anyone new to caring for cacti!
Scarlet Ball Cactus (Parodia Haselbergii)
The scarlet ball cactus is native to South America, where they live in a moister environment than more cacti. While overwatering is still harmful and should be carefully avoided, they can handle more moisture than other cacti while you play around and find the perfect watering practices.
These cacti do not do well in a lot of direct sun. They can handle direct sunlight in the morning and later in the day but can be harmed by the direct sun during the hottest hours of the day. A low-lit environment is just fine for these little guys.
2. Crown Cactus (Rebutia)
The crown cactus is native to South America, and in the wild, they grow in clusters on mountains. Among the clusters of crown cacti, their flowers will bloom from the base between individual cacti.
While this cactus is best if it receives some bright light, it can grow and live in a range of conditions, including indoors and with low light. This cactus needs very little water, yes, even for a cactus. The soil should dry out almost entirely before you go to water it again. This cactus is another great one for cacti newbies because it is very resilient and adaptive. So, poor lighting, irregularly water, and so on are not optimal but will not cause substantial harm to this cactus as fast as other, more sensitive cacti.
Crown Cactus (Rebutia)
3. Zebra Cactus (Haworthia Attenuata)
The zebra cactus looks a bit more like other succulent varieties but is a beautiful cactus that can sustain itself in low light. The zebra cactus grows tapered, dark green leaves (think similar to the shape of an aloe vera plant) with white horizontal stripes and spikes along the edges.
This cactus benefits from some full sun but turns red when sun exposure is excessive and often benefits from a decent amount of shade or survives just fine indoors with low light. When you water the zebra plant, you will want to get water throughout all the soil, but make sure it thoroughly dries out before watering again. The easy care and small size of these plants make them a popular indoor cactus choice.
These plants need long nights or periods out of light, at about 14 hours long to trigger blooming. This makes them a great houseplant, as they do well away from direct sun an add bright color wherever you place them.
Christmas Cactus (Schlumbergera Bridgesii)
The Christmas cactus can be fidgety to care for with the amount of light and temperature affecting how flowers bloom. Many Christmas cactus owner may also prune their plant in early summer to encourage more flowers as well.
This cactus takes a considerable amount of water, needing to be watered completely through the soil whenever the top of the soil is dry to the touch. This cactus is a good choice for someone who has experience caring for cacti or is willing to research and learn precisely how to care for it.
How To Take the Best Care of Cacti Indoors or In Low Light:
Cacti are not meant to sit in wet soil for long periods of time. Combining poor lighting and overly wet soil can create quite harmful conditions for the plant. Soil that is heavy or very dense will trap moisture, and the plant will not take up immediately.
Combining poor lighting and overly wet soil can create quite harmful conditions for the plant.
To avoid your cactus sitting in wet soil, you will want to pot it in a cactus mix. Look for the ingredient perlite which improves aeration and keeps the soil loose and prevents it from becoming compact to allow for drainage.
2. Be very careful not to overwater
An indoor cactus, especially one kept in low light, will need far less water than other house plants or any cacti you have grown outside. Overwatering will likely kill the cactus, and low light conditions make the plant even more vulnerable and sensitive to any adverse effects.
When watering, consider if misting or watering is better for the cactus you have. Water at the base of the cactus, so water reaches the roots and can be absorbed. You will want the water to reach the roots of the plant, but you do not have to add so much water that it drips from the pot. Generally, you should repeat watering when the top inch of soil in your pot is dried out.
3. Use a pot that allows excess water to drain out
Root rot describes damaged roots that are beginning to prune and no longer take up water. This is a common problem for cacti that can be caused by pests, pathogens, or overly wet soil. The last two suggestions will reduce the chances of this as well, but a pot with drainage holes will help significantly by letting out excess water and allowing aeration in the deepest part of the pot. In low light, indoor environments, this is especially important to make up for the drying effect of sunlight.

Growing Your Cactus Indoors with Low Light
If you love cacti, but do not have the most optimal environment, there is no need to feel defeated!
As you can see, cacti as a group share core characteristics, but individually, each has unique care needs. Your responsibility is to make the most of the environment for your plant by allowing what light you can, using good soil, watering responsibly, and so on. If you follow these guidelines, your cacti will thank you by growing vibrantly in your space.
If you make an informed choice as to what cactus to keep indoors- minding that it is suited for the environment and aware of how to best care for it, you can brighten up any space with these intriguing little plants!
Unlike most green-leafed and flowering indoor plants, cacti are incredibly hardy and don’t require an abundance of care, water, or climate control. As long as their basic needs are met, cacti can thrive just about anywhere you place them.
So, is cactus a good indoor plant? As a general rule of thumb, yes. Cacti love dry conditions and warm, comfortable temperatures typically found in the home. They also won’t need to be watered often or pruned. Though, some species will do better indoors than others because of their size and sunlight requirements.
In this article, we’ll be discussing the best cactus plants to have indoors and how to care for them to help them thrive.
The Best Kinds of Cactus to Have Indoors
Cacti are increasingly popular plants because of their large variety of appearances. These plants come in different shapes, textures, colors, floral features, and sizes — with some species, like the Saguaro cactus, reaching heights of 40 or more feet. With that in mind, it’s crucial to choose a cactus species that is better suited for indoor growth.
Here are our favorites:
1. Old Lady Cactus
Adorned with long white hairs, the Old Lady Cactus might just remind you of your grandmother’s hair or that rugged cardigan she likes to wear.
This lovely indoor cactus blooms a ring of pink or purple flowers on the top of the plant during the spring and would look beautiful sitting on a window sill or near a sliding glass door. It also has large spines that poke through the white fluff.
Old Lady cactus
Old Lady Cactus Care:
Place in full sun (around 6 to 8 hours daily to keep hairs looking healthy)
Water once every other week or once a month during the winter
Plant in sandy, well-drained soil
Consistent sunlight exposure is key to growing a healthy Old Lady Cactus, so if you don’t have an area in your home that receives sufficient light, you may want to consider a grow light to supplement the hours your cactus isn’t getting sun.
2. Christmas Cactus
With a large number of plants going dormant during the winter, the colder months can become drab and gray. That’s where the Christmas Cactus comes in. This gorgeous indoor cactus generally blooms bright red flowers at the end of each branch but can also clothe itself in flowers of white, purple, yellow, or pink.
What’s great about the Christmas Cactus is that it requires less light than other species, meaning you can place it virtually anywhere in your home without the worry of needing consistent light.
Christmas Cactus
Christmas Cactus Care:
Water your Christmas Cactus once a month.
Place in an area that receives 4 to 6 hours of sunlight each day. 4 hours each day will still lead to blooms, however, 5-6 hours per day will result in more colorful, fuller flowers.
Plant in well-drained soil, preferably sandy. You could even supplement a third of your regular potting mix with sand.
Avoid overwatering. Christmas Cactus are prone to root rot and will only need to be watered once every 3 or 4 weeks. These plants do best in average home temperatures of 65 to 70 degrees Fahrenheit.
3. Bunny Ears Cactus
As cute as its name entails, the Bunny Ears Cactus is a slow-growing cactus that’s perfectly suited for an indoor environment. Rather than cover itself in long, pointy spines, this cactus is coated in small groups of off-white prickles resembling fuzz. It grows between 2 and 3 feet tall and up to 5 feet wide on average, making it great for sunrooms or placement next to large windows.
Bunny Ears Cactus
Bunny Ears Cactus Care:
Bunny Ears Cactus should be watered once a month or every three weeks, depending on sun exposure and indoor temperature.
This cactus should have access to partial sunlight — about 4 to 6 hours of direct exposure daily.
As with all cacti, plant in well-drained, preferably sandy soil.
With adequate sunlight, the Bunny Ears Cactus will bud in late spring and begin sprouting purple fruit and white flowers in early summer.
4. Star Cactus
A native Texas cactus, the Star Cactus is both interesting to look at and petite, making it a perfect choice for an indoor garden display. This is an adorable rounded cactus with 8 sections, each lined with white prickly dots. The Start Cactus will only reach a width of about 6 inches at most, so it can be placed practically anywhere in the home.
Star Cactus Care:
Water your Star Cactus once a month — no more and no less. Excess water could lead to root rot.
This cactus requires adequate sunlight, around 6 to 8 hours daily, to be the healthiest.
Soil should be rich in nutrients and allow for proper water drainage. Slightly sandy soil is preferable.
In the center of the cactus, a bright yellow flower blooms in the spring from March to May. The center of the flowers are generally orange and reach diameters of 3 to 5 inches across.
Star cactus
5. Moon Cactus
One of the more interesting indoor cactus options, the Moon Cactus is a popular choice for homes because of their bright coloring and unique shapes. They have a moon-shaped crown sitting atop a central green stem that commonly comes in shades of pink, orange, and yellow. They’re also quite petite, only growing a few inches tall and 8 or so inches in diameter at the fullest part of their body.
Moon Cactus Care:
Moon cactus requires watering once every three or four weeks.
Exposure to direct sunlight for four hours per day is all that’s needed to keep this cactus healthy.
The soil should be rich and sandy and able to drain well. Fertilizer is also occasionally recommended for these cactus plants.
Moon Cactus is two cactus plants grafted together. Because the colorful part of the Moon Cactus isn’t able to survive well on its own, the lower portion allows it to have a prolonged life. The downside to Moon Cactus is that they don’t have as long of a lifespan as other species. While other cacti may live for multiple decades, Moon Cactus may only survive for a single decade or less.

General Cactus Care
To keep your cactus happy and healthy, there are few general care tips to keep in mind, such as:
Ensuring the plant is draining water well. One of the biggest killers of cacti is overwatering and water-retention. The majority of cacti will only need to be watered once a month. Be sure that the soil allows for proper water drainage, as pooled water will result in root rot.
Keeping the temperature consistent and warm. An indoor temperature of between 65 and 70 degrees is perfect for all cacti. Temperatures that are too cold will kill a cactus, and so will moisture, so your home should also have dry air.
Giving your cactus adequate sunlight. Keeping your cactus in a window sill or near a glass door is your best bet. Sufficient sunlight is necessary, but too much can fry your cactus. If your plant requires partial light, be sure to move it to a shaded area after it’s had its fill of sun.
Overall, cacti are set-and-forget plants that don’t demand an abundance of care. Just as long as they receive enough light and watering now and again, they’ll be good to go year after year.
Final Thoughts
When it comes to cacti, there are a few varieties that do better indoors than others. Star Cactus and Moon Cactus are two of the most common indoor cacti because of their unique appearances, small size, and vibrant coloring. Keep in mind that less is more when cacti are in question—only water when necessary and place them in a window that receives consistent sunlight.
When people think of cacti, they often imagine the hot, arid desert; like other succulents, a cactus can thrive outdoors. However, what if you wanted to grow your own cactus indoors? Will it do just as well, or even better?
Will a cactus grow better indoors or outdoors? A cactus can be grown both inside your home and outside equally well. However, regardless if you choose to grow cacti indoors or out, note that they can only grow successfully in specific environments.
Cacti are naturally occurring in the desert, where the climate is dry, and there is very little rain. In other words, they thrive in hot, dry conditions. If you live in an area that gets a lot of rain (or just more rain than the desert), then it is best to grow your cactus indoors. These plants need a lot of sunlight, but so long as they are placed in the proper position, they are low maintenance and easy to take care of.
Types of Cactus that Can Grow Indoors
Cacti are known for their wide variety of species. While they are commonly thought of a desert plant, many can thrive indoors as well. That being said, some cacti do thrive better indoors than others. Here, we have compiled a list of cacti that make great indoor plants:
Bunny Eared Cactus
Also known as Opuntia microdasys. These cacti originate from Mexico and are named for their appearance. These cacti are covered in brown pickles, and in the summertime, they often grow white flowers and purple fruits. They can grow to be up to three feet tall, which is around the size of many other average house plants.
Old Lady Cactus
Also known as the Mammillaria hahniana. It is a type of pincushion cactus of the mammillaria family, which has 250 species within it! The old lady cactus is known for its ring of pink or purple flowers that grow and bloom in spring. They are easy to take care of and only need to be watered once a week.
Old Lady Cactus
Moon Cactus
The moon cacti’s proper name is Gymnocalycium mihanovichii. They vary in shape, size, and color, but typically the popular variety is the Hibotan cactus. It originates in South America and comes in many bright colors. They need to be watered more than many other cacti, usually once a week. They also need only partial light, and all in all, they are still easy to take care of.
Moon Cactus
Star Cactus
Less commonly known as the Astrophytum asteria. The star cactus has also been called the sand dollar cactus and the sea urchin cactus. It is easily identified by its round body, which is sectioned into eight pieces. It also has tiny white dots leading up to the top center of the cacti, where it blooms a yellow flower in the spring. It has a small (2-6 inches in diameter) appearance, which makes it an ideal house plant to manage.
Easter Cactus
Also known as the Hatiora gaertneri, this plant is native to Brazil. The Easter cactus usually blooms anywhere from late winter to early spring. Its flowers are beautiful and come in a variety of colors from white to orange, or even lavender. They have also been known to bloom red and even peach colors.
The flowers on the Easter cactus are not the only attention-grabbing feature on the cacti. They are also known for their rickety stacked appearance, which creates a very unusual shape.
Unlike regular cacti, they thrive in colder temperatures. How much you water the plant can vary anywhere from every 3 to 6 weeks. The amount of water the cactus receives mostly depends on the environment the plant is grown in. The best temperature to grow them in is between 50 to 65 degrees Fahrenheit.
Types of Cactus that Can Grow Outdoors
As previously mentioned, many types of cacti grow best outdoors. This list is for those of you that live an environment ideal for outdoor cactus growth:
Barrel Cactus
Also known as Ferocactus, the barrel cactus is known for its round or barrel-like shape. There are a few different varieties of this cactus. Some of the most popular are the California barrel, the blue barrel, and the golden barrel. Their flowers bloom in May and June and are commonly either red or yellow.
Barrel Cactus
Thanksgiving Cactus
Scientifically known as the Schlumbergera truncate, this cactus is known as the Thanksgiving cactus because it blooms around the Thanksgiving holiday every year. Like the Easter Cactus, it thrives in colder temperatures. It blooms throughout the winter. Even though it flourishes in colder temperatures, it cannot grow in a region where frost occurs.
Prickly Pear Cactus
The prickly pear cactus is found in areas that are prone to droughts. They can thrive in back yards but are unpopular for such a scenario because they do shed their needles. They can produce either purple, yellow, and red flowers. They usually only need to be watered every three weeks.
Prickly Pear Cactus
Queen of the Night
Also known as the dutchman’s pipe cacti, the queen of the night is native to Brazil. This cactus’ actual name is Epiphyllum oxypetalum; however, it is known as the queen of the night because its flowers bloom at night. It produces large white blooms, and when planted in slightly acidic soil, it will bloom frequently. Fun fact: this plant actually grows on trees!
Totem Pole Cactus
The totem pole cactus is slow growing; however, it can grow up to twelve feet in height! Instead of visible spines, the notches on this cactus look more like wrinkles. Similar to the queen of the night, the totem pole cactus blooms at night, producing pink flowers and red egg-shaped edible fruit.
Totem Pole Cactus
To thrive, this plant needs full sunlight during the daytime and does not need a lot of water. They live well in drought-prone areas and survive best in well-draining, gravely soil. Therefore, it needs very little water. It is an excellent plant for backyards because it does not shed its needles.
Conclusion
Cacti are part of a group of plants known as succulents. They are generally found in desert areas but have gained growing popularity as house plants. Certain cacti thrive best indoors, and others are more likely to survive outdoors.
There are even certain cacti like the totem pole cactus and the Saguaro cactus that survive both indoors and outdoors. Both these cacti are slow-growing and can eventually be moved to the outdoors when they become too tall to keep inside.
Owning cacti gives your home a modern feel and is excellent for anyone who loves plants but doesn’t have time to water them. They are also excellent housewarming gifts for first-time homeowners!
In conclusion, whether you choose to grow cactus indoors or out, it is vital that you’re mindful of their sunlight and watering needs so they can thrive in the environment they’re kept in.
Many of us tend to think that watering plants is quite easy, right? Well, it might be, but the unfortunate thing is that you might be doing it the wrong way. How you water your cactus plant is crucial since incorrect watering accounts for almost 90% of all cacti deaths! The good news? Once you figure out how to water your plant correctly, it is almost impossible to kill it.
So are you wondering how to water a cactus indoors? One of the best ways of watering your indoor plants is by avoiding the spray bottle at all. With a spray bottle, you are only going to wet the top few inches of the soil which doesn’t help in any way. Instead, try as much as possible to drench your potting mix to the bottom. The best way to do this is by pouring a lot of water on the soil near the base of the plant or soaking the entire pot in a water pan for a few minutes.
In this post, we are going to teach you how to water your indoor cactus plant properly and how to make it thrive. Read on to find out everything you need to know about watering your indoor cactus.
Growing Cactus Indoor: A Quick Overview
Cacti plants usually have a unique, stark beauty and produce the most beautiful flowers in the entire plant. Fortunately, growing desert cactus in your house isn’t difficult.
Successful gardening of these hardy plants in your house requires you to stick to simple rules. Do the right thing, and you will have beautiful plants that will decorate your interior spaces throughout the year.
Some cacti species will bloom after three or four years while others may take longer. However, getting your indoor cacti bloom shouldn’t be a big issue as long as you know how to take good care of them.
One of the easiest ways of killing your indoor cactus is by watering it incorrectly. Keep in mind that cacti plants hold water in their stems and other plant tissues. These plants make use of the stored water to survive in dry areas.
Therefore, overwatering can be catastrophic. However, they still need to be provided with sufficient water to survive the indoor environment. The best way to determine if your plant requires watering is by checking the soil moisture content.
To do so, carefully stick your finger into your potting mix and pay close attention to how it feels. Do not just touch the surface soil but make sure you penetrate at least two inches downwards.
Always pay close attention to how your plant appears.
If the soil feels wet, moist, or damp, do not water your plant. Wait until it dries out completely before watering. How much and when you water your indoor plant largely depends on the season.
During the active growing seasons (spring and summer), your plant requires more water. For most indoor plants, watering at least once every ten to 14 days should be enough to keep your plant happy.
During the dormancy season (winter and fall) the plant requires less water. At this time, you need to water less frequently and less thoroughly. Generally, water your plant at least once every three or four weeks.
Always pay close attention to how your plant appears. If it seems shriveled in between watering sessions, you may need to water it more. However, if you are unsure of what to do, then you will be safe if you water it lightly.
After all, under-watering cactus is better than overwatering it. Therefore, feel free to experiment a few times until you figure out what works best for your plant.
What Is the Best Time to Water Your Indoor Cactus?
The time of day you choose to water your indoor cactus will also greatly impact its health.
Ideally, you should water your plant in the evening or early morning when temperatures are low, and the evaporation rate is at its lowest. This way, more moisture will remain in the soil for longer, allowing your plant to benefit from it.
Avoid watering your plant during the middle of the day when temperatures are high. This is the time when evaporation occurs rapidly, meaning that a lot of water will be lost in the process.
Never leave standing water on top of your soil for more than an hour. The moment you pour it, work to ensure that the excess drains out of the pot. Otherwise, your plant will drown in water.
How to Water Your Indoor Cactus Correctly
You may know whento water your indoor cactus but do you know howto do it properly? The watering technique is the most crucial thing that will determine whether your plant thrives or dies.
Ask any experienced gardener, and they will tell you that watering is not just a matter of pouring water on your plant.
The watering technique is the most crucial thing that will determine whether your plant thrives or dies
Before we discuss the right watering technique, let us start by pointing out the wrong watering technique that most of us tend to use.
Do not use a spray bottle to water your plant. You should also avoid misting.
The truth is that no matter the number of times you squeeze that trigger, you are only going to wet the top few inches of your soil. Unfortunately, there aren’t any roots there to absorb the water.
In fact, this watering technique can be quite detrimental to your cactus plant because it will be forced to start growing roots towards the soil surface other than down and out of the pot. With time, you will end up with a weak root system that cannot support the plant for long.
To water your plant correctly, make sure you fully drench the soil to the bottom. So, how do you achieve this? Pour water on the soil near the base of the plant and make sure it is a lot of water. It shouldn’t be a trickle.
You can even consider wetting all of the soil in the pot if it is possible. This watering technique encourages the growth of a wide and healthy root system that will support your plant for many years.
Some gardeners prefer soaking the entire plant pot in a water pan for some time before taking it out. This is also another good way of ensuring that water reaches the bottom soil.
Should I Water My Indoor Cactus During Winter?
Most cacti plants are naturally dormant in winter, meaning they don’t need to be watered as much.
However, if your plant is starting to show some signs of dehydration, such as wrinkled leaves, you can water it sparingly. This can help keep the soil moist until temperatures begin to rise again.
During this time, focus on watering just enough to keep your plant from drying out completely.
You don’t want to overwater it during this time as the roots may still be too cold to absorb the moisture, and you might end up with a bunch of rotting cacti plants.
Also, ensure that the environment is warm enough for your plant before attempting to water it. Room temperatures above 65 degrees Fahrenheit are ideal for most cacti plants.
How to Water Indoor Cactus Grown in a Pot without Drainage Holes
Let us start by stating that we don’t recommend growing cactus in containers without proper drainage holes because the results can be catastrophic.
But, if you have been to plant display shows, you must have noticed the new trend. Cacti and other succulents being integrated into all kinds of cute artsy crafts.
It is no longer surprising to find cacti plants grown in teacups, terrariums, succulent birdbaths and all types of containers.
We don’t recommend growing cactus in containers without proper drainage holes
Although this may seem adorable, it isn’t the best way to grow these plants. Keep in mind that not having proper drainage puts your plant at a significantly high risk of developing root rot. Don’t think the few pebbles at the bottom of the container will create drainage.
If you have your cactus perched in such a container, there is only one way of approaching watering. Waterless and pray that things don’t get worse.
Instead of drenching your container, simply pour a small amount of water (maybe a teaspoon full) at the base of your plant.
You should also try to stretch out the amount of time between watering sessions as much as possible. Also, be sure to keep your container in a relatively dry place that receives lots of light. Consider a south-facing window if you are in the northern hemisphere.
While you may want to dry your soil completely before watering, the truth is that it may not be possible. So, all you have to do is establish what works in your favor and stick to it.
Should I Water My Indoor Cactus After Repotting?
Occasionally, you may need to repot your indoor cactus. Whether it is a mature plant outgrowing its pot or a young one that needs a change of soil, you should know how to handle the situation.
When you take your cactus out of its old container, there are chances that the root system will be severely damaged. This means the plant will need extra care for it to bounce back.
The rule of thumb is to let the plant rest for at least two weeks before watering it again. During this time, you can mist the soil lightly if it seems dry.
Once your cactus has settled into its new container, you can go ahead and give it a full drink of water. However, more importantly, ensure that the soil is completely dry before the next watering session.
Remember that watering your indoor cactus correctly is essential if you want it to thrive in its new pot.
Should You Use Soft Water, Hard Water or Rainwater?
Water hardiness is usually determined by the concentration of ions in the water, and it may have an impact on the overall health of your cactus.
Soft water is a term used to refer to water that has been treated with potassium or sodium to remove minerals such as magnesium and calcium. Soft water contains high amounts of sodium.
Rainwater is the preferred water for cacti plants.
Hard water contains high concentrations of dissolved mineral particles such as magnesium and calcium. Rainwater in its natural state is soft water.
So, what is the right type of water to use in watering your cacti plants?
Soft water contains relatively high concentrations of sodium which can cause harm to your cactus. The excessive amount of sodium in the water can build up on the skin of your plant resulting in stunted growth.
The high concentration of sodium may also harm your plant in the long run since it interferes with proper absorption of water and hydration.
3. Rainwater
This is the preferred water for cacti plants since it contains the right amount and balance of minerals necessary for your plant to thrive. Always try to collect as much rainwater as possible and store it properly for later use on your cactus.
Summary
Although cacti plants are hardy, they still require proper watering to thrive. Generally, the watering technique you choose to use will have a significant impact on the overall health of your plant.
No matter how you decide to water your indoor cactus, the target is to get the soil wet from top to bottom and allow excess water to drain out of the container as quickly as possible.
The good thing is that once you master the right watering technique, it becomes pretty easy to take care of your indoor cactus plant!
