Vermiculite

Vermiculite can be found in potting soil or purchased by itself in four different sizes for gardening with vermiculite. Germinate seeds using the smallest size of vermiculite as a growing medium and the largest size for improved soil aeration. Vermiculite is the name of a group of hydrated laminar minerals (aluminium-iron magnesium silicates) that look like mica. 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 is generally a neutral 7.0 pH but is dependent upon the source from around the globe and its reaction is alkaline. It is very lightweight and mixes easily with other mediums.

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. Perlite may also be found in potting soils, but vermiculite is far superior for water retention. Vermiculite, although less aerating than perlite, is the amendment of choice for water-loving plants.
