Masitera Pumice excludes itself from others, it's actually treated with NEEM extract to control bacterial and fungal diseases because of its pesticidal properties. While it absorbs the additional nutrients given to the plants it also allows the treatment to spread into the soil mixture over time and protect them from pest problems. Pumice increases the water retention capacity of the soil mixture, It provides air permeability and supports root development. No other soil amendment is as widely used by succulent growers and collectors as pumice.
