Mineraland Diatomaceous Earth (3–6mm)
Mineraland Diatomaceous Earth is a lightweight, highly porous growing medium made from the fossilised silica skeletons of microscopic algae (diatoms) - a naturally abrasive, absorbent mineral. In its granular 3–6mm form it's a brilliant soil conditioner, soaking up water and nutrients then releasing them steadily to the roots while keeping your mix open and free-draining.
Use it on its own as a semi-hydro medium, or blend it through potting, bonsai and succulent mixes to improve aeration and drainage. It's durable, holds its structure and resists compaction, so the benefits last for years.
