when is the best time to dethatch your lawn
Dethatch the Lawn. The best time to dethatch a cool-season lawn is early fall or early spring and a warm-season lawn is early summer. For small areas, use a thatching rake, which is a sharp-tined rake that rips the thatch out of the lawn, to remove thatch; leaf rakes or hard rakes may also be used but may not work as well depending on the situation.
