Dethatching is the  process of removing the layer of dead and decaying grass, roots, and debris matted between the soil and growing grass. A thatch layer of 1/2 inch or more prevents air, light and water from reaching the turf’s root zone. 

You should dethatch in early fall before you fertilize, or in the spring after the grass has begun to green.
