Horticultural Perlite helps plants thrive and improves soil structure, keeping it workable for years. The surface of each particle of perlite is covered with tiny cavities providing an extremely large surface area for holding moisture and nutrients necessary for plant growth. Perlite is primarily used in potting soils and propagation beds to loosen soil, optimize drainage and prevent compaction. Because perlite is sterile, it is free of disease, seeds, and insects.
