Nature's Footprint Pumice Soil amendment, 5-Gallon

Pumice is a type of igneous rock which is formed from molten or partially molten material. Providing excellent aeration to the soil, pumice loosens heavy clay soil and retains moisture well. With the addition of as little as 10-Percent pumice in potting media and garden soils, you will significantly improve your soil. The porous nature of pumice allows it to hold vital nutrients in surface pores, which helps regulate fertilizer feedings. Pumice is a great bedding additive to worm composters, adding air space, preventing matting, and helping to control moisture.
