Stone dust powder, a byproduct of stone crushing, is used in gardening to improve soil texture and drainage. It provides trace minerals like calcium, magnesium, and potassium, promoting plant health. Mixed into the soil, it enhances aeration, supports microbial activity, and aids root growth. Stone dust is especially beneficial in heavy clay soils, making them more friable and reducing waterlogging. Use sparingly, as excessive amounts may alter soil pH or compact the soil.
