“Dethatching” lawns refers to the mechanical removal from a lawn of the layer of dead turfgrass tissue known as “thatch.” This residue is bad for your grass, as it keeps water and nutrients from seeping down to grass roots. Preventing thatch buildup is not nearly as a big part of lawn care as is mowing, but you should not overlook its importance to the long-term health of your grass.
The Best Time for Dethatching Lawns is either in early spring or in early fall.
