What is the difference between vermiculite and perlite?
The difference between perlite and vermiculite is their function. Perlite acts as an aerating agent and helps the soil shed water. Vermiculite acts as a sponge, allowing the soil to retain moisture. They work together to give the soil the right balance of drainage and water retention. Vermiculite and perlite are becoming increasingly popular for use in horticulture. Sowing, cutting and propagation businesses increasingly add these substances to the (potting) compost to ensure a better, more airy structure. Our specialist will explain more about vermiculite and perlite in this article.
