Our pumice is a favorite around here—and for good reason. It’s 100% natural, triple-washed, low dust, and ready to use straight out of the box. Whether you're mixing soil for succulents, cacti, or bonsai—or just giving your houseplants better drainage—this stuff does the job beautifully. And as a cherry on top, available in both 3/8" and 3/16" sizes. We keep things simple and honest: no dyes, no fillers, and no nonsense. Just pure volcanic pumice, sustainably mined right here in the USA. We hand-pack every box ourselves from our family-run shop in California, so you know exactly what you’re getting—clean, consistent quality every time. Each box holds about 32 lbs of pumice and measures 18x12x10—easy to store, easy to use, and perfect for shops offering soil by the scoop, creating custom mixes, or selling refill options. We’re proud to share this with fellow plant lovers and small businesses who care about what goes into their soil—and into their gardens.
