What Is Cactus Soil?

Cactus soil or cactus mix, in general, is soil that is specifically made or mixed to meet the cactus’ natural environment and at the same time provide its delicate root system the best soil to flourish as these roots do not thrive in overly dense soil.

A specific mix of organic materials is what makes a cactus soil perfect. However, using soil that is in high organic matter will only hold excess moisture that will result in root rot.

The mix of these organic matters offers much more advantages compared to non-organic soil, which is why it is highly recommended to use cactus mix rather than using pure regular organic or non-organic soil.


Is Cactus Soil Necessary?

Chances are, you might be thinking if it is really necessary to transfer your already healthy cactus to a cactus soil setting. Depending on what growing conditions your cactus is in, it may be doing well for now.

But as it further grows and develops, a risk for its health follows as well.

There is no certainty that cactuses will live a long life in a soil that is not suited for them, whereas if you use cactus Soil, this gives them superb living conditions.

Basically, cactus soil mimics the native environment in which these desert plants are accustomed to growing in. In addition to that, these mixes give the cactus the upper hand of utilizing the soil for its delicate roots.

Furthermore, cactus soil improves the drainage which keeps the roots from rotting.

The right cactus soil will address the unique needs of the cactus, which makes them do well in their pots. These conditions need to be met in order for the cactus to thrive.

Cactus Soil vs Potting Mix

To put it into perspective, cactus soil is specifically mixed with matters that are fit for the cactus’ living conditions from drainage, moisture removal, to aeration.

Potting mix is simply not reliable as it can delay the drainage, and create excess moisture which is critical for the cactus’ health.

In terms of aeration, it is possible that the cactus’ roots might encounter problems as their roots require a specific amount of air for their roots to grow at a healthy pace.

Below are the major benefits of cactus mixing, and these emphasize the good of what it does to the welfare of your cactus and to yourself too.

1) Saves You Money

Yes, mixing your own cactus soil saves you money because buying cactus soil at Plant Nurseries and Garden Centers actually costs more than regular potting soil.

Without going to spend the extra dollar, you can simply make or mix one of your own by following one of the 4 Cactus Potting Soil Recipes in this article.

2) Prevents Rot

As aforementioned, cactus soil helps the cactus to form a better basis for its roots, unlike regular soil that will only do harm than good.

The inappropriate soil that is high in organic matter will again, only hold unnecessary moisture that can cause your roots to rot.

3) Fast Drainage

Cactus soil is also known for having excellent drainage which both involves quick evaporation and quick drying. These two elements help your cactus maintain that soil condition it wants to be in.

4) Better Moisture Retention

Cactuses are known to be very different from other plants when it comes to watering. Cactuses do not require the same amount of water normal plants do, which is why it is important to keep the moisture retention just right.

This can be achieved with cactus soil because its function is to eliminate moisture, not retain it.

So, a little amount of water from your hand sprinkler will be sufficient. You will not have to worry about moisture retention because the cactus soil will do its job effectively.

5) Enhanced Aeration

With organic potting soil, cactuses will have difficulty getting the proper amount of air for their roots as this type of soil is not for its roots. On the other hand, cactus soil is less dense, which allows the cactus’ roots to get the air it requires.
