Vermiculite 100L Bag

Vermiculite water retaining soil improver Vermiculite is the name of a group of hydrated laminar minerals (aluminum-iron magnesium silicates) which look like mica. Perlite may also be found in potting soils, but vermiculite is far superior for water retention.

Horticultural vermiculite is processed with massive heat that expands it into accordion shaped pellets composed of multiple layers of thin plates. It will not rot, deteriorate, or mould and is enduring, odourless, non-toxic and sterile.

Vermiculite added to the garden or vermiculite in potting soil increases water and nutrient retention and aerates the soil, resulting in healthier, more robust plants.

Vermiculite, although it is able to hold less air than perlite, is the correct choice for more plants liking more water.
