DESCRIPTION

Perlite is a naturally occurring volcanic glass formed by water mixing with obsidian. It has the unusual property of greatly expanding when heated.  The expanded material is a brilliant white. For gardeners, it makes compost more open to the air, while still having good water-retention properties. It can be used in a variety of ways - mixed into our compost to increase the aeration or used on its own for ie root cuttings.
