If you’re looking for a potting mix that will help your plants thrive, look no further than vermiculite. This is a super lightweight and sterile material that is perfect for use in potting mixes and seed raising. Vermiculite has a high surface area, making it ideal for propagation.

Vermiculite is a clean, naturally occurring, non-toxic aluminum iron silicate mineral that has been superheated to a high temperature and is an excellent addition to potting mixes because it helps aerate the mix and maintain moisture levels. This is also useful in hanging baskets because it helps to hold water and prevent the roots from drying out. This is an essential component of any gardener’s toolkit.
