Perlite: The Aerating Champion of the Garden
How to Use Perlite. Incorporating perlite into your soil mix is simple. A common ratio for potting mixes is one part perlite to two parts soil, but this can be adjusted depending on the needs of specific plants or the existing soil structure. For plants that require excellent drainage, like succulents and cacti, increase the proportion of perlite.
