A thick thatch layer builds up quickly in Michigan lawns where cool-season grasses push heavy spring growth. Once it gets ahead of you, it blocks water and nutrients from reaching the root zone regardless of how consistently you mow or water. Pulling it back gives turf room to breathe and absorb what it needs. Dethatching works especially well combined with aeration and overseeding in the same season for a fuller turf reset.
