PermaTill is a soil additive that provides permanent aeration for clay or compacted soils. It is produced by firing a special slate at temperatures in excess of 2000° F. Soils that have become too hard and dense for easy cultivation and proper root development are improved by the addition of PermaTill because the pores in the rock act as tiny reservoirs, storing moisture and any available soluble nutrients which are easily released to roots.

PermaTill is also sold as VoleBloc because it can be used to protect plant roots from becoming a feast for a common garden pest – voles. Read more about voles and using VoleBloc as a preventative barrier in our Do-it-Yourself article Critter Alert!
