These plants fall into the family of succulents, but unlike conventional succulents, they have evolved to suit drier regions. Their leaves are morphed into small sharp thorns so as to lose less water due to a reduced surface area and also for water storage. Have a look at the information below to learn more!

What To Consider Before Growing Cactus Plants?

Cacti are low-maintenance plants that require moderate care compared to other types of plants. This makes them perfect for beginner gardeners and it is also a great housewarming gift. Additionally, they make excellent indoor houseplants.

To ensure their success, though, a few things need to be taken into account. So, the following information is essential if you want to know how to care for a cactus plant indoors.

Choose a Forest Cactus

Cactus plants come in two varieties which include the desert and forest types. Because they have spines to support them, desert cacti are more likely to survive harsh conditions. Contrarily, forest cacti with no spines, such as the Blue Candle or Christmas cactus, are better suited to being grown indoors because they lack the strength to withstand harsh conditions.

Make Sure your Plants have Enough Light

As long as they are placed in an area that receives at least 4 to 6 hours of sunlight per day, cacti can be grown indoors. To ensure they are etiolated, we advise rotating them daily on your brightest windowsill, which is typically a southeast-facing window.

Choose a Green Cactus

Green cactus plants are more tolerant of low light conditions than other succulents. So, if you think your home isn’t adequately lit, Blue Candle and Angel Wing are great options.

Underwatering is Preferable to Overwatering

Although they can tolerate some water neglect, cacti are very sensitive to overwatering. Ensure the soil is completely dry before watering again. One way to do this is by stabbing a wooden chopstick or moisture meter into the ground or potting soil.

It’s not yet time to water your cactus if there is soil or water on the chopstick. Additionally, it is strongly advised to give your plant a soil mix that is 50% organic and 50% inorganic. Doing this will enable you to prevent root rot caused by overwatering, by enhancing the infiltration of water into the soil.

What Is The Best Soil For Cactus Plants?

When learning how to care for a cactus plant indoors, it is also important to have knowledge about the best soil to grow them in. The best soil for these plants shouldn’t be constantly wet because this will cause root rot, killing your plants. Cacti thrive in porous, pebbly, or sandy soil as long as it has good drainage and aeration.

Although this soil is not particularly unique, it does differ from typical soil in some ways. In order to provide the plant with nutrients, the ideal soil must also contain a significant amount of organic matter. This is because it also helps to retain moisture, preventing the soil from drying out after watering.

A good cactus soil mix is also quick-draining. Commercial potting mediums contain peat moss in addition to the essential components of good potting soil, which is excellent for growing cactus plants. The majority of commercially available cactus potting soils on the market are capable of producing mature plants from seed.

However, it’s not a one-size-fits-all strategy as each plant will have its own demands depending on several factors. Therefore, you must develop your own unique cactus culture if you want your desert or jungle cactus to flourish. Here’s a video that will enlighten you on the cactus varieties. 

What Pots Are Best For Cactus Plants?

If you know how to care for cactus plants indoors, then you will know that plastic, terracotta, or ceramic glazed pots or containers are best for cacti. Their growth is significantly influenced by the type of container, its shape, and size.

While some containers are ideal for growing your plant, others may not be suitable. Take note of the container’s shape when buying one for your cactus plant.

When purchasing a planter, here are some qualities that you should consider:

1. The size of the container should be similar to that of the cactus. This is due to the fact that cacti’s roots are frequently short, and if they are planted in a big container, they will stay in the middle of it.

2. Cacti grow best in cylindrical, short, and square containers. Avoid selecting containers that are too deep, tall, or narrow.

3. All of the soil in the container should be “used” by your cactus. Therefore, there shouldn’t be an excessive amount of soil that the cactus roots can’t penetrate. There should only be a little room for drainage at the bottom and surrounds of the plant.

How to Care for a Cactus Plant Indoors?

  1. A cactus plant requires little maintenance once it has become acclimated. These are the basics to learn when figuring out how to care for a cactus plant indoors.
  2. The soil should be kept damp beneath the surface in the spring and early summer when the cactus is doing the majority of its growth. So, the soil should always be damp at a depth of about an inch from the top.
  3. Adequate temperature ranges are important for your plant to grow its best.
    Lots of sunlight is recommended as these plants grow best with at least eight hours of direct light daily.
  4. Specialized fertilizers should be used for cacti. Cacti will lack nutrients from the majority of common fertilizers.
  5. When repotting your cactus, it is advisable to use the same potting medium as the plant is sensitive to change and can take a while to adapt.
