A process of mechanically removing plugs of thatch and soil from the lawn is called core aeration. It has many benefits including: opening the soil, reduceing compaction, improving water infiltration, improving rooting, and reducing thatch which aids in reducing lawn stress. The plugs are left on the surface to break down (usually within a couple of weeks) and reincorporate soil into the thatch layer, creating a better growing medium for turf grass. We perform this service in the fall when root growth is at its optimum.
