Do You Have a Thatch Problem?
Healthy grass has thatch, and a thatch layer that is less that 1/2″ think is not a concern. You only have a problem if the thatch layer gets too thick so that water and air have trouble getting to grass roots.
To measure the thickness of thatch, poke around the grass until you find the brown layer near the bottom of the grass blade. With your finger or a stick, poke a hole through the brown layer to the top of the soil. Measure the thickness of the thatch.
When is the Right Time to Dethatch?
Dethatching causes a lot of damage to your grass and should be done at a time when the grass is growing so it can fix the damage before the next dormant period.
