You might ask, “Can cactus houseplants grow indoors? Yes, of course, they do! Not only do they grow indoors, but they thrive inside the house. Plant enthusiasts grow and propagate them because they are not sensitive. As a result, they are one of the best drought-tolerant plants that require minimal care and low maintenance.

But be careful; houseplant cactus varieties are sensitive to frost and overwatering. So, you may choose an area in your house that cannot be reached by the cold draft and water them only when the soil dries out. Nevertheless, these aesthetic cactus houseplants add beauty to your space; you don’t even need wallpaper if you have them! So, why not collect them now.

 

 

 

 

Benefits of Having Cactus Indoor Plant Varieties

With improved air quality, it results in better cardiovascular conditions. Who doesn’t want to breathe fresh air? It’s good for the lungs and for the earth too.

Another contribution of cactus houseplant to humans and the environment comes from ambient or background noise. For example, do you observe a humming sound when you live in a busy area of the city? That’s the one. Yes, cactus houseplants lower background noise in your space; thus, they help you relax.

There are more – all types of cactus absorb EMF (electromagnetic fields) radiation. So maybe, have a small cactus indoor plant on your table while using your laptop. It’s a great idea! Further, cactus houseplants improve humidity during a dry and sunny day, so you feel cooler inside the house.

You can choose several types of cacti, depending on color, size, and shape. Many cactus plant types grow well indoors, and others thrive outdoors. So, it would help to determine which ones you want to put inside your house based on their characteristics, such as moisture, sunlight, temperature, and humidity requirements.

Five Ailments of Cactus Houseplants

Cactus houseplants, both outdoor and indoor varieties, may suffer from specific ailments or pests that you need to check from time to time. If one of your cacti caught an infection or infestation, here are some things you can do to take care of the problem before it gets worse. But, you have to isolate first the poor guy so that the infection or infestation won’t spread to nearby houseplants.

 

1. Brown or Black Spots 

Fungi on the leaves usually cause brown or black spot infections. You can take care of this problem with fungicides containing copper sulfate, neem oil extract, or chlorothalonil.

2. Spider Mites 

Spider mites can infect cacti plants with delicate webs under the leaves or joints. You can solve this problem with miticide spray, a concentrated form of chemical insecticide. It is specific to spider mites which results in immediate knockdown and elimination. 

3. Brown Patches

Brown patches on cactus stems indicate a pest infestation by aphids and scale insects. Treat this problem with petroleum jelly combined with insecticidal soap, horticultural oil, or insecticide sprays.

 4. White cottony substances 

White cottony substances on cactus stems indicate an infestation of mealybugs. You can deal with this problem by applying horticultural oils or neem oil extracts combined with insecticidal soap.

 5. Mealybugs

Pincushion cacti develop brown ridges on their spines if infected by mealybugs and cochineal scale insects. To get rid of these pests, apply imidacloprid as a drench to the soil around the plant. Then, follow it up with systemic injections to get absorbed by its roots to protect from these bugs as it grows.

Growth Requirements and Maintenance of Small Cactus House Plants

When you first purchase your cactus houseplants, it’s essential to plant each one in well-draining soil. You may add sand or pebbles to the regular potting mix before planting. Next is watering cactus house plants by saturating the soil and stopping once you see the water draining from the pothole.

Since these desert plants can grow under indirect sunlight, place them near a glass window or a glass door. However, if you notice brown spots on your plant’s stems, there might be cold drafts or hot air flow entering that area. So, transfer them to another place with favorable conditions.

Although a small cactus home plant needs little water, it doesn’t like freezing temperatures or frost. When exposed, it will start to rot after one. However, some cactus houseplant types can withstand minus 20 degrees Fahrenheit or below, depending on their varieties. They have mechanisms like spikes or spines that keep out frost to prevent stem freeze.

 

 

1. Water

Since the cactus has adapted to desert life, it prefers less-than-perfect soil conditions. It’s essential to plant each one in well-draining soil. You may add sand or pebbles to the regular potting mix. Next is watering cactus house plants until excess water drips out through the drainage hole in the bottom of the pot. Avoid overwatering by waiting for the soil to become parched entirely before giving them another drink.

 

 

 

 

2. Sunlight

Cacti need indirect sunlight if you keep them indoors year-round. However, when held outside during summer, they require at least six hours of direct sunlight daily. During winter, when it’s gloomy, you can provide artificial light from fluorescent bulbs or LED grow lights but avoid incandescent lights.

3. Temperature

During the growth period from spring to summer, cactus houseplants require a temperature of 70 to 75 degrees Fahrenheit in the daytime and 60 degrees at nighttime. When they are dormant from fall to winter, they need a temperature of 45 to 55 degrees Fahrenheit. They do not grow when the temperature is below freezing for any period. The length of time that cacti can withstand cold varies by species.

4. Humidity

Indoor humidity is often as low as 30 percent during winter months, so it’s essential to keep your cactus houseplants away from cold drafts and heated rooms unless you mist them regularly.

 5. Fertilizer

Cacti do not need fertilizer if grown in good potting soil and allowed to dry out between waterings. However, if the plant is still growing and developing “pups,” feed with a diluted liquid fertilizer monthly for best results.

6. Growing Medium

These desert plants grow best in well-draining potting soils with pebbles and sand. The cactus houseplant is best grown in pots indoors to protect from cold drafts and extreme temperatures.

 7. Pruning and Trimming 

If you notice any dead leaves on your plant’s stem, snip them off to encourage new growth. It would be best to prune only during springtime when flowering or developing buds because trimming or pruning can damage or even kill the plant.

 8. New Cactus Houseplants Care Tips

When you buy a new plant or repot and propagate an old one, remember to place your cacti in bright, sunny locations where they’ll receive plenty of filtered sunlight. Then, follow the recommendation of watering cactus house plants when the soil dries up, and make sure not to get any water on the leaves or stems.

Periodically prune away dead or dying branches using sharp scissors before repotting the plant into a larger container if needed. Then, apply fungicides containing copper sulfate, neem oil extract, or chlorothalonil to eliminate mold and other fungi that grow on the surface.

 

 

Important Reminders on Cactus Houseplant Care

1. Giving cactus house plants lots of indirect sunlight. 

During the summer months, you should keep your potted cactus out of direct sunlight, which can cause burn damage. If the cactus does not receive enough indirect light, its spines will fade. It will also eventually fall off after two or three years in unfavorable conditions.

In addition, if brown spots appear on stems,  move them away from cold drafts or heated rooms since this condition damages their health. When the plant is indoors, it’s essential to place them away from cold drafts and heated rooms because these areas can cause rot or burn.

 2. Watering cactus houseplants when the soil completely dries out.

It helps if you keep cacti in a well-draining pot since they don’t require nutrients and fertilizer. If the cactus house plants get too much water, you will notice the formation of rot at the roots. It almost guarantees the death of your cacti.

 

3. Keeping cactus houseplants with minimal care and attention.

If you are busy or travel a lot, cacti are perfect for you to collect as houseplants. Also, because they are desert plants, you can plant them outside in the summer months or bring them inside when winter comes to protect them from the extreme cold. So, it’s best to plant them in pots for easy movement. 

Caring for your plant babies is simple. They do not need high humidity levels like other plants; instead, they grow well in dry air. When comes down to these little guys, they need little water and lots of indirect sunlight. So, planting cactus and propagating it do not require special skills, attention, and effort.

 

How to Tell Between Cacti and Succulents?

Many consider Cacti to be one of the succulent family. And while they are closely related, they are not the same. Succulents are plants that retain water in their leaves, stems, or roots. They may also have thickened, fleshy tissue for storing water. The difference between cacti and succulents is that cacti are native desert plants that evolved from the arid climate for survival. They are the product of adaptation to their natural environment.

1. Succulent leaves vs cacti stems

Succulents are plants that retain water in their leaves, stems, or roots. They may also have thickened, fleshy tissue for storing water to withstand heat. On the other hand, cacti are native desert plants that evolved from the arid climate for survival. They are the product of adaptation to their natural environment. So, they can withstand prolonged drought because of their very thick and sturdy skin.

2. Manner of growth

Succulents almost always grow in clusters, while cacti usually grow alone or in small groups.

3. Water requirements

Both cacti and succulents need water when the soil completely dries out. There’s is no general watering schedule because it also depends on the humidity inside your house.

4. Sunlight requirements

Succulents and cacti require the same types of sunlight: bright but indirect light year-round. They also grow more slowly in low light conditions than exposed to direct sun.

5. Effects of cold drafts

Neither type of plant grows well with cold air or drafts, so keep them away from doors and windows during winter if you want to avoid damage due to colder weather.
