What Is Dethatching?

Dethatching is the mechanical removal of excess thatch from a lawn.

How to Understand It

Tines or vertical blades loosen accumulated material so it can be collected. Dethatching targets the organic layer above the soil; core aeration removes soil plugs. Equipment names and aggressiveness vary, so inspect the layer and follow local turf guidance.
