Pumice: Quick Overview

Pumice is a lightweight volcanic mineral that permanently improves drainage, aeration, and structure in potting mixes without breaking down like organic components do. It is especially useful in substrates for cacti, succulents, bonsai, many aroids, and any plant that struggles when ordinary soil stays dense or wet for too long, because the particles create lasting air spaces around the roots. Unlike heavier stones, pumice adds mineral openness without making a mix difficult to handle, and it holds only modest moisture, which helps pots dry in a more predictable way. Used alone for certain dry growers or blended into general mixes, it is one of the simplest ways to make substrate behave more cleanly and rot risks easier to manage over time. That improves day-to-day use.
