Lawn expert Dr. Tom Samples of the University of Tennessee Agricultural Extension Service explains that dethatching is essential to maintain a lush, healthy lawn.
Thatch is the layer of built-up plant material between the green top growth and the roots of grass plants. Thatch develops naturally as lawn grasses grow and slough off roots, shoots and leaves. Some thatch helps protect the roots, but excessive thatch prevents moisture, oxygen and nutrients from penetrating the soil.
