Centipede Grass Struggles? Mowing Height Could Be the Culprit

A centipede lawn that's mostly dead with clover taking over is a frustrating sight. But before you reach for herbicide, check your mower deck. The most common mistake with centipedegrass is cutting it too short.

Why Height Matters for Centipedegrass

Centipedegrass spreads via stolons — above-ground runners that creep across the soil surface. These stolons are vulnerable to extreme temperatures. Grass blades act like a protective canopy, shielding the runners from scorching summer sun and freezing winter winds. When you mow too low, you strip away that insulation.

Low mowing also thins the turf, creating open space for weeds like clover to invade. A dense, properly mowed centipede lawn naturally suppresses most weeds.

Find the Sweet Spot

Measure your mowing height. Centipedegrass performs best between 2 and 2.5 inches. If you've been cutting lower, raise the deck immediately. The grass will thicken over time, and the clover pressure should ease.

When to Renovate

If centipedegrass is sparse and clover dominates, renovation may be faster. Spot-treat clover with glyphosate (Roundup, KleenUp), wait a week, then vigorously rake the soil to create a good seedbed. Sow centipede seed at the recommended rate and keep the top half-inch of soil consistently moist — never let it dry out. With steady watering, you can establish a solid stand by fall.

Patience and proper mowing height are the foundation of a healthy centipede lawn. Get the height right, and the grass will do much of the weed control for you.
