Thatch accumulates in your lawn as dead roots and
decomposing grass and other debris accumulate. Even a lawn
that appears to be green on the top layer can be full of thatch beneath that surface of green. As thatch accumulates, it prevents water, nutrients, sunlight, and air from reaching the roots of the
grass. As this occurs, the grass literally suffocates and is starved, which causes an unhealthy condition that can kill your lawn. Removing thatch increases the amount of water and nutrients that
are available for your lawn to consume, which will enhance your lawn’s resistance to disease, and promote a lush, green lawn.
