Is it a good idea to use sepiolite to grow plants?

The roots are a part of the plants that, despite being underground, it is very important that they are properly aerated, otherwise they will not be able to absorb the water they need and, therefore, the leaves will wither and die. To avoid this, it is essential to use substrates that have good drainage and that remain moist for a reasonable time, but… is sepiolite one of them?

If you have or have had a cat, you have probably heard of it. It is the typical sand that is used so that this animal can relieve itself inside the house, thus preventing it from staining where it should not. It is cheap, and due to its porosity it could be very useful for our plants.

Sepiolite is an absorbent mineral that belongs to the group of so-called phyllosilicates whose origin is sedimentary. It is opaque, with a very low hardness and matte. It is also known by the name of sea foam since it floats on water.

It is found in very porous soil masses and has a pH of 8.3 . It is generally white in color although sepiolite can also be seen in yellowish or grayish tones.

Can it be used on plants?

Yes and no. Let me explain: sepiolite is a substrate that has the drawback that it degrades over time and ends up forming mud that makes it difficult for water to drain . But it is very cheap, so much so that a 10kg bag can cost you 9 euros. So it can be used, but at most two years, and not on all plants (succulents -cacti and succulents- and bonsai will not do well).

Of course, before trying it, it is very important that you put a little in a dish with water and leave it overnight. If the next day it stays fine, then yes you can use it.
