- Vermiculite - 250 gm packet.
- 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. 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.
- Vermiculite increases aeration and moisture retention, and through its high cation exchange capacity (CEC) it minimises fertilizer leaching.
