What is Thatch? How to Control Thatch
At the base of your grass blades is your turf, a layer of earth that serves as the surface of your lawn. Beneath this, sandwiched between your turf and the soil is thatch, a tightly knit accumulation of dead but un-decomposed organic debris. Thatch is a normal part of your lawn. It's natural function is to conserve water, insulate the grass from fluctuating temperatures, and increase your turf's resilience. The correct amount of thatch is less than 1/2 inch.
