Pumice

Pumice is a volcanic rock that is used in soil mixes to aid aeration, retain moisture and loosen heavy, clay soils. It is best to use with cacti and succulents or other plantings that need increased drainage and air flow. Pumice is better than perlite or rice hulls because pumice is porous and allows microbial life to grow. Pumice also contains trace minerals and has a neutral pH.
