But clippings cause thatch, don’t they?
Grass clippings break down quickly and don’t cause thatch if grass is mowed regularly. The brown, spongy material we call thatch starts with thick grass stems and roots. These grass parts break down slowly and can accumulate as a thatch layer, especially with our cooler soil temperatures and slower microorganism activity. Dethatch your lawn every 1 to 3 years with a dethatcher or power rake.
