Diatomite is a sedimentary rock formed over millions of years by the fossils of ancient marine plants.

Today it is used as a grow medium for all types of gardening due to its large surface area and ability to retain moisture while being very free draining. It is slow to break down in soils and is used extensively in the cactus, succulent, and bonsai trades.

It provides bioavailable silica to plants and will help keep temperatures even in growing containers, a big advantage for no-till container gardeners and bonsai growers.

We advise you wear a mask and gloves when handling this product.

This is the cheapest grow medium to ship as it is quite lightweight compared to zeolite.

NOTE - Please note the color may change in this product due to varying moisture levels when we process it onto packaging.

Always great quality

I use Dr Greenthumbs in all the potting mixes that we create and sell on Woo Plant. I use Diatomite, Limestone, Pumice, Zeolite to add to the DGR mineral cactus soil and find this to be a perfect gritty mixture for Peyote, Astros and Brain cactus. The DGR minerals are such great quality and you can always rely on that.
