Exfoliated vermiculite has been long established in the horticultural market. Mixed with peat or other growing substrates it is used to produce a range of growing media to suit every application.
Vermiculite increases aeration and moisture retention, and through its high cation exchange capacity (CEC) it minimizes fertilizer leaching. Manufactured at high temperatures, vermiculite is sterile. It is an excellent carrier and extender for fertilizer and pesticides and works well as packing material for bulbs and tubers.
