St. Augustine Lawn Care Guide for Houston, TX Homeowners
Everything Houston homeowners need to know to keep St. Augustine lawns thick, green, and weed-free year-round.
Overview
St. Augustine is the most common turf in Houston for good reason: it loves the heat, tolerates partial shade, and looks lush when treated right. Here is how to keep yours that way.
Why St. Augustine thrives in Houston
The clay-heavy soil and humid summers in Houston are exactly the conditions St. Augustine evolved for. It spreads via stolons, recovers quickly from light damage, and shades out most weeds when kept dense.
Mowing height matters more than you think
Cut St. Augustine at 3.5–4 inches in summer and 3 inches in cooler months. Cut shorter and you scalp the crown, expose soil to weed seeds, and invite chinch bugs and gray leaf spot.
Watering deep, not often
Two deep waterings per week of about an inch each is the right target across Houston. Deep watering pushes roots down where they survive summer; shallow daily watering trains roots up where they fry first.
Fertilization windows for Houston
A modest spring application after green-up and a fall application before dormancy is enough for most Houston lawns. Over-fertilizing pushes lush growth that fungal disease loves.
Common pests in Houston St. Augustine
Watch for chinch bugs in dry hot pockets, gray leaf spot in humid stretches, and take-all root rot in chronically wet areas. Early identification beats late treatment every time.
