What is scalping in turf grass?

Scalping in turf grass is a mowing practice that removes too much of the grass blade, leaving the base of the plant exposed. This can damage the grass and make it more susceptible to disease and drought. Scalping can also lead to the development of thatch, a layer of dead grass and organic matter that builds up on the surface of the soil. Thatch can prevent water and nutrients from reaching the grass roots, and it can also make the grass more susceptible to disease and drought.

To avoid scalping, mow your grass at a height that is recommended for your grass type. The recommended mowing height for most cool-season grasses is between 2 and 3 inches, and the recommended mowing height for most warm-season grasses is between 1 and 2 inches. You should also mow your grass regularly, about once a week, to prevent the grass from getting too long and becoming scalped.
