How Often Should You Mow Your Lawn in Texas?
A clear, season-by-season mowing schedule for Houston-area lawns — and the cut-height mistakes that cost homeowners a healthy yard.
The short answer
For most Southeast Texas lawns, weekly mowing from late March through October and bi-weekly mowing through the cooler months keeps turf healthy and curb appeal strong. Skipping weeks in peak season is the single fastest way to stress your grass and invite weeds, fungal disease, and patchy thinning that takes months to recover from.
If you only remember one rule from this article, make it this one: in Houston, Pasadena, Deer Park, Baytown, and the broader Greater Houston area, your lawn wants to be mowed weekly from late March through October. The rest of the year, every two weeks is usually fine.
Why frequency matters more than length
The 'one-third rule' is the foundation of healthy mowing: never remove more than one-third of the grass blade in a single cut. When you skip a week in June, your lawn keeps growing — and the next mow has to scalp the lawn down to bring it back to height. Scalped St. Augustine recovers slowly, exposes the soil to weed seeds, and invites disease in our humidity.
Mowing more often, at the right height, actually means less work over time because clippings are short enough to mulch back into the lawn instead of clumping. Those mulched clippings return free nitrogen to the soil and reduce fertilizer needs.
Cut height by season and turf type
St. Augustine — the most common Houston-area turf — wants 3.5 to 4 inches in summer and around 3 inches in cooler months. Higher cuts in summer shade the soil, protect the crown, and reduce water needs. Going shorter than recommended in summer scalps the crown and lets weeds in.
Bermuda is the opposite — it likes 1.5 to 2.5 inches and tolerates frequent mowing. Lower, more frequent cuts on Bermuda actually encourage density.
Zoysia sits in the middle at 2 to 3 inches. It's a slower grower than St. Augustine, but skipping weeks still scalps it back to ugly when you finally cut.
What about winter?
From December through February, most Houston-area warm-season lawns are dormant or close to it. Growth slows dramatically. Bi-weekly or even monthly mowing is fine during this window — just stay on top of fallen leaves, which can smother turf and cause spring dead spots if left in place.
Signs you're mowing wrong
If you see yellow, frayed grass tips after mowing, your blades are dull. If you see brown patches in the days after a cut, you scalped — either cut too short or skipped too long. If your lawn is thinning in the same spots year after year, you may be mowing too short for the shade level there.
When to bring in a pro
If your property is more than a quarter-acre, has heavy shade pockets, or you simply don't want to spend Saturdays behind a mower, a weekly residential lawn care plan from Klean Kuts is usually less expensive than DIY once you factor in equipment, fuel, blades, sharpening, and time. Same crew every visit, fixed service day, sharp blades, correct cut height — that's the formula for a lawn that looks great year-round.
