Perlite is a light, hard, aerated, white mineral, formed from volcanic glass, used in potting mixes to add open and porous drainage, provide aeration to plant roots and hold oxygen, a little moisture and nutrients from soluble fertilisers.
Perfect for creating your own potting mix or raised bed mix in bulk. Simply add compost, soil and other components to make your own specialty blend, especially for plants that love aeration and excellent drainages like cacti, succulents and orchids. The angular properties of Coarse Perlite make it particularly useful for creating free draining potting mixes.
Perlite in seed raising mixtures encourages quicker germination and improved seedling growth. Seedlings are easily removed from Perlite with little damage to the roots as they transplant with minimum disturbance.
