Permatill is a very unique soil amendment that is made by heating a specific type of slate to 2,000˚F and causing it to expand. This expansion creates an open and porous structure that is great for improving your soil by increasing drainage, aeration, and more! Permatill is great for breaking up heavy clay and compacted soils and it also naturally protects plants from moles and voles!
