What does lawn look like after dethatching?

Determine if the Lawn Needs Dethatching Examine your grass for an underlying layer of thatch. It will look like a matting of old, grayish-brown grass stems that have grown together.

What time of the year should you dethatch your lawn?

The best time to dethatch your lawn is when it’s actively growing and the soil is moderately moist. For cool-season grasses, that’s early spring or early fall. For warm-season grasses, dethatch in late spring through early summer (after the second mowing). That’s when your grass is growing most vigorously.
