Scalping your lawn invites weeds and stress. Here is the right mowing height for Texas grasses.
Never remove more than one-third of the grass blade in a single mow. Cutting shorter shocks the plant, weakens roots and exposes soil to sunlight — exactly what weed seeds need.
Bermuda and Zoysia do well mowed a touch lower, while St. Augustine prefers to stay taller — around three inches. Taller blades shade the soil and crowd out weeds naturally.
Mowing at the right height with a sharp blade, and watering deeply but less often, builds deeper roots that survive Texas summers far better than a scalped lawn.
