This means that product is majority 3/8" down to 1/4" granule size. Minimal fines. Dried and screened before packaging Pumice is a volcanic rock that is commonly used in horticulture and gardening as a soil amendment or growing medium. It is lightweight and porous which makes it an ideal addition to potting mixes and soils. Used to improve soil structure and drainage. When added to soil, pumice helps to create air spaces that allow roots to breathe and water to drain more easily. This is particularly useful in soils that are heavy or compacted, as pumice can help to prevent waterlogging and improve aeration. Pumice is also used as a top dressing for plants, especially in bonsai and cactus gardening. The small particles of pumice help to prevent soil erosion, retain moisture, and provide a stable surface for the plants to grow on.
