Perlite is made from volcanic rock, which is heated and crushed until it explodes in order to transform the rock into small white pieces. It has medium water retention ratings and low nutrient retention ratings. It is added to soil mixes in order to improve the drainage capability of both soil-based and soilless potting mixes.
Use perlite to root cuttings or grow cacti, succulents, epiphytes, and other plants that benefit from quickly draining soil with plenty of aeration. Perlite can also offer a humidity boost to plants that need it.
Perlite helps insulate plant’s roots from extreme temperature fluxuations. It’s also used as a protective coating on pelleted seeds. Perlite is lightweight, odorless, clean, and easy to handle. It has a pH of 6.6 to 7.5. Add perlite to your soil for plants which need their soil to dry out between waterings, such as cacti or succulents.
