Our 10 cups of 3/8+ - 1/4+ pumice is ideal those wanting a clean hand screened pumice of a larger size for soil mixs or to improve the drainage of water sensitive plants. Our pumice is a natural volcanic product mined in the Southern Cascades Mountains of Oregon. You get only clean pumice... no rocks, roots or other debris. Known as the rock that floats, pumice has many tiny gaps or air pockets that allow roots access to oxygen, nutrients and water. Pumice improves both water retention and drainage of your soil mix.
