We all know cactus are mostly found in deserts which means they need less water, less care, and a warm environment. So, they need soil which does not hold the moisture in it for a long time. later we will tell you how cactus get moisture from the soil.

Sandy soil is perfect for them it has excellent aeration and drainage properties. Cactus plant needs plenty of air, especially in the growing phase.

Let’s find out more about cactus potting soil and growing conditions.

Why cactus only grows in sandy soil?

To understand it completely you need to understand the way cactus rooting systems works. You may have heard of succulent tissue that suck the water from the rooting system and wax coatings of cactus which helps to store the water content. But you will be surprised when you know about the working pattern of cactus roots.

Cactus roots hold water in two ways. In the first method, the root structure holds the water and does not allow water loss to the soil by shrinking its size. In a second way, the plant uses its wide roots which are away from the plant itself and cover the wide area in the open field. These large roots absorb moisture content from the large part of the soil.

Cactus roots absorb water in a matter of minutes. Once the rainfall starts in the desert the root system gets 100% activated and absorb the water drops from the upper layer of the soil. Deserts do not get rainfall for more than 5 to 10 minutes and this type of rainfall only moist the upper few inches of soil.

If the cactus roots do not act quickly than the rainwater content in the soil gets evaporated in less than 5 minutes due to dry and hot weather.

In short cactus roots absorb water whenever it is available, they store it and shrink themselves to avoid water loss. If you grow cactus in other than sandy soil, this increases the chances of root rot up to 90 %. This means the soil should be sandy soil with very less water holding capacity.
