Discover the many benefits of pumice stone for gardening. Formed from partially to fully molten material, pumice rocks take with them all the exciting features of an igneous stone:
- Small vesicles that make rocks lightweight and breathable
- Trace amounts of minerals like phosphorus, manganese, copper, iron, magnesium, calcium, potassium and sodium
- Neutral pH with no yucky odors
- Won't host harmful insects, nematodes or fungi
Garden pumice is highly effective for loosening heavy soils and clay. The material retains moisture well but is also easily leached, making pumice stone an ideal balance for gardening in containers. Small vesicles in the rock also help soil to aerate so nutrients and drainage are easier to control. Use as little as 10% pumice stone in a growing medium for noticeable results. Rocks don't break down, rot or compact, but remain robust over time while allowing plant roots plenty of room to thrive. Also great for composting, mulches and turf and lawn management. Looking for an effective way to pack and store bulbs, roots and tubers? Pumice stone also works great for aerated, nutrient, rich gardening storage.
