Vitax Perlite Compost Additive, 10 Litre Bag

Perlite is a naturally occurring volcanic rock which, when heated to super-high temperatures, produces incredibly lightweight, micro-porous granules.

When mixed with compost, these granules hold water and nutrients in the compost and also improve aeration and drainage, creating a healthier growing environment and stimulating root development and growth.

Add to seed and cuttings compost for even greater success.
