Will Cactus Grow Indoors

Despite being recognized for their love of sunlight, many cacti grow well as houseplants. For some unusual decor, place one on your windowsill or in your living area. The ideal houseplant, indoor cacti typically require less light and are smaller in stature.

Bunny Ears Cactus (Opuntia microdasys)

The bunny ears cactus gets its name from its look and is native to Mexico. Its two pads are designed like bunny ears. They should be handled carefully since they have glochids or brown prickles on them. The bunny ears cactus is the ideal indoor plant because it may reach heights of two to three feet. If given enough light, it will blossom with white flowers and bear purple fruits in the summer.

Chin Cactus (Gymnocalycium)

Gymnocalycium is a kind of cactus native to South America and is frequently referred to as the “chin cactus.” Greek for “naked kalyx,” its name alludes to the flower buds’ lack of hair or spines. Some chin cactus like shade, while others do better in sunlight, depending on the kind.

Saguaro Cactus (Carnegiea gigantea)

Although it grows slowly, the Saguaro cactus can reach a height of forty feet. This indicates that you can use it as an indoor plant for a number of years before relocating it outside. It has the traditional cactus appearance thanks to its barrel-shaped body. This plant, which is a native of the Sonoran Desert, needs a lot of sunshine. Place the plant in direct sunlight if it is being maintained indoors.

Old Lady Cactus (Mammillaria hahniana)

The mammillaria family, which comprises 250 species, includes the old lady cactus as a subspecies of pincushion cactus. It is renowned for its halo of small pink or purple flowers that bloom in the spring and possesses hairs and spines. A sandy potting mix should be used to plant the old lady cactus, and it should receive water every other week.

Star Cactus (Astrophytum asteria)

The star cactus, also known as sea urchin or sand dollar cactus, can be recognized by its circular body that is divided into eight slices. It has small white spots and white hairs all over it. It produces a yellow blossom in the spring. The star cactus is the perfect indoor plant because its diameter only reaches two to six inches.

Easter Cactus (Hatiora gaertneri)

Easter cactus, a native of Brazil, blooms in late winter or early spring. White, orange, and lavender are just a few of its bloom colors. The plant has a distinctive shape because of the way its spines are piled on top of one another.

Christmas Cactus (Schlumbergera bridgesii)

The Christmas cactus, which is frequently mistaken for the Thanksgiving cactus, blooms in the dead of winter. It boasts vivid red blossoms and is frequently given as a Christmas gift. The Christmas cactus thrives in average indoor settings. Don’t overwater plants because it will make their roots rot. Although this plant can thrive in low light conditions, its blossoms benefit from additional light.

Moon Cactus (Gymnocalycium mihanovichii)

The moon cactus, also referred to as the chin cactus, varies in size, shape, and color. The hibotan cactus is a well-known cultivar. Its South American origins can be traced to its vivid red, pink, yellow, and orange hues. On window sills that receive some light, these little plants flourish.

Is it acceptable to have cacti inside the home?

Although cacti are attractive plants with powerful protective energies, their spines are an issue. They are pointed objects that project focused energy into the surrounding space and resemble tens of thousands of tiny arrows. Cactuses should never be placed in a living room, bedroom, or front entry because of this.

Without sunlight, can cacti grow indoors?

If you are unfamiliar with cacti plants, you might be unsure of their ability to live in the absence of sunlight. These are desert plants, after all, and you would be inclined to believe that shielding them from the sun is beneficial for them. Is that indeed the case? Most likely not.

Can a cactus survive in the absence of sunlight? The quick response is “no” Like other plants, cacti require sunlight to survive. Although these arid plants can endure brief periods of darkness, they require a lot of sunlight to grow and bloom. A mini-cacti plant typically needs four hours or more of direct sunlight each day to thrive.

Some cacti species are marketed as low light plants because they lack spines. The Christmas cactus is a nice illustration of this kind of cactus. The issue is that if you don’t give your cacti plants enough sunlight, they’ll become malnourished and maybe die.

Which cacti thrive indoors?

The sight of a 40-foot saguaro cactus punctuating the landscape will stay with everyone who has traveled to the Sonoran Desert for any length of time. These magnificent plants can survive for two centuries, and blossoming can take up to 40 years. This cactus’s sluggish growth rate makes it possible to grow one as an indoor houseplant for many years as well. Give your saguaro as much light as you can, and only water it once a month or so.

Where in my home should I place a cactus?

Nowadays, cacti and succulents are highly popular indoor plants, therefore taking good care of them is crucial. They occur in a wide variety of sizes and shapes, ranging from the small to the enormous. Because they share traits that enable them to endure in arid conditions, cacti and succulents belong to the same category.

The majority of succulents and cacti are endemic to desert environments. They will therefore thrive in conditions with lots of light, good drainage, hot temperatures, and little wetness. However, some cacti and succulents, like Schlumbergera, enjoy semi-shady and wet environments because that is their natural habitat.

The easiest way to take care of cacti and succulents is to try to mimic their natural environment. The essential factors you should take into account when taking care of your succulents and cacti are listed below.

Light, temperature and ventilation

It is advisable to arrange cacti and succulents in a bright area because they do best with good light sources. A place that faces south will get plenty of light. But be careful not to place them in direct sunlight since the strong light may cause the plants to turn yellow. The best kind of light for growing cacti and succulents depends on the species that you are using. For instance, forest-dwelling epiphytes like Rhipsalis require some shade, whereas an Echeveria requires strong light.

It is ideal to keep the plants cool at night, between 8 and 10 degrees Celsius, during the fall and winter. The plants will survive in high temperatures, but they require sufficient ventilation in the spring and summer.


Since Westland cacti and succulent potting mix has included girt and sand for the best drainage, it is a good compost to use. Additionally, it has the ideal quantity of nutrients for your succulents and cacti.

Watering and feeding

It’s a popular misperception that succulents and cacti just need a tiny bit of water. Although their leaves and stems can store water, allowing them to survive in dry environments, they will not grow in environments with little water. Your cactus or succulents’ ability to develop successfully depends on regular watering. Underwatering results in shriveling while overwatering stunts growth.

Instead of using tap water to water plants, use lukewarm rainfall. This is because the minerals in tap water can deposit on the leaves and accumulate in the soil. Additionally, minerals obstruct the plant’s access to vital nutrients.

Spring and summer

The plants need to be watered at least once a week during the growing season. Give the soil a good soak when watering, letting any extra water run away. Every time you water the compost, give it a little time to dry out.

Utilize Westland Cacti and Succulent Feed, a recommended recipe to use, to feed your plants once a month. They create more robust growth that is more resistant to disease and has superior flowering thanks to it. Simply take a 5ml quantity of the feed from the dosing chamber and mix it into 1 liter of water.

Autumn and winter

The plants enter a period of rest at this time. Reduce watering so that the potting mix dries out in between applications. The type of succulent and the environment it is in will determine how frequently it has to be watered. Winter-flowering cactus should be kept warm and watered frequently now, whereas desert-dwelling cacti don’t need to be watered. Cacti and succulents don’t need to be fed during this time.


The optimal time to repot cactus or succulents that are pot-bound is in the spring. To replant:

  • Before carefully taking the plant from the pot, water it and let it drain. Use folded paper to shield your hands from the spikes.
  • To avoid damaging the roots, remove the old soil from around them with a thin stick, like a chopstick.
  • The new container, which has a slightly larger diameter, should be filled with potting soil before placing the plant inside of it.
  • The remaining potting mix should be added to the pot and compacted.
  • To stop the rotting of injured roots, stop watering for a few days.

The finest care for your succulents or cacti comes from maintaining these conditions. The most crucial thing to keep in mind when taking care of your plant is that you are trying to mimic its natural environment!

Can cactus clean the air?

The peruvian cactus species, Cereus peruvianus, is the one that is typically utilized to absorb this kind of radiation, but it should be noted that not all research have found the same results.

Cacti, on the other hand, are plants that can detoxify interior environments, which are typically full of unseen chemical compounds that most plants can absorb.

The Christmas cactus, also known as the Schlumbergera, lends a special hand in our decorating, especially when its priceless blooms burst into bloom. It will work wonders if we put it in a chemically-contaminated space, but we should keep in mind that it requires more frequent watering than a typical cactus does. It will be enough to watch out for the earth and keep it from drying out.

In particular, it will assist us in removing pollutants like formaldehyde, volatile organic compounds present in agglomerates, plywood, paint, varnish, glue, cosmetics, and tobacco smoke from settings.

In conclusion, cacti are a green investment because of their resilience and minimal water needs. It will be sufficient to water them once a month, and it is essential to let plenty of natural light enter them. The truth is that the bigger they are, the more resilient they are; nevertheless, if we take good care of the young ones, they will also live a long time, and if we give them adequate soil and fertilizer, they will also become bigger.

Cacti and other species mixed together is another fascinating idea. The miniature date palm, fountain palm, ivy, tape, and ficus are some of the most decontaminating plants.

All plants have the ability to purify the air, however some are more efficient than others. It depends on their capacity to metabolically decompose the airborne poisons into organic materials that they can consume.

We shall thus obtain a more or less healthy environment as a result of its more or lesser absorption. Because of this, choose the proper plants is crucial if we want to purify the air.

When it comes to decorating and creating a cleaner atmosphere that meets our needs, the secret is to choose a variety of plants that combine a lot of traits. Let’s not squander time thoroughly recording the types of pollution we have at home and the animals that could perform the task more effectively.

How frequently does a cactus need watering?

The most frequent reason for cacti failure is improper watering, whether it is done too much or too little. Cacti have evolved to store water for extended periods of time and can maintain moisture through droughts because they are endemic to arid regions and dry temperatures. They have a limited capacity, which is why over-watering can result in a variety of issues.

When it comes to regularity, watering your cacti will largely depend on the season but also on the variety. Checking the soil is the easiest technique to determine whether your cactus needs water: It’s time for a drink if the top inch is dry. That entails applying the “soak and dry procedure” on cactus.

What is the soak and dry method?

The soak and dry technique is thoroughly wetting the soil until part of it begins to flow out the drainage hole, then waiting until the mixture is nearly dry before wetting it once more. If done properly, this strategy will help them endure a period of under-watering should you need to travel or leave the house because it takes use of their natural tendency to store water (or if you just get busy and watering falls to the wayside, as happens to all of us now and again).

Watering during the growing season versus the inactive season

Like with many houseplants, the season affects how frequently you need water. It becomes more crucial that you get in the habit of examining the soil to determine whether your cacti are thirsty. A healthy cactus needs watering every one to two weeks during the growing season, according to general wisdom. The frequency changes to once every three to four weeks during the off-season.

Even then, it’s crucial to examine the soil. The same way that not all interior spaces and not all cacti are alike. The only way to be certain that your cactus require watering is to carefully examine the soil to determine how dry it is because there are so many different factors.
