When added to soil or compost, vermiculite absorbs nutrients, preventing them from being washed out and then releases them as required to plant roots. It helps to retain water in the soil or compost and holds moisture near to plant roots.
When used when sowing seeds the excellent aeration and water retaining properties of Vermiculite encourage faster germination and improve seedling establishment. Seeds can be sown in Vermiculite alone or in a mix of compost and Vermiculite.
Vermiculite is a lightweight, non-toxic material that has been heated to a high temperature. It has a lovely and very attractive golden colour.
It can be used as a decorative topping which has the added bonus of protecting delicate plants and insulating them against frost damage.
