Houston Lawn Care Advice for St. Augustine, Bermuda & Zoysia

Todd Farber, Aggie Horticulturist and Garden Guy, has helped Houston-area homeowners with their lawns and landscapes since 1991.

Todd Farber

Aggie Horticulturist · Garden Guy

Todd Farber is the Aggie Horticulturist behind Garden Guy. He earned his horticulture degree from Texas A&M in 1991 and has spent the three decades since working hands-on with Houston-area lawns, landscapes, plants and soils — learning firsthand how our heat, humidity and heavy clay change what actually works in a yard.

Garden Guy has served Houston-area homeowners since 1991 as a real landscape design, installation and horticulture company — not a mowing crew or a spray service. Ask Garden Guy is the educational side of that work, where Todd and Sabrina Farber help homeowners understand their lawn, garden and landscape problems. The advice here comes from decades of local, in-the-dirt experience, not generic national lawn content.

Where this advice applies

Written specifically for Houston & the Gulf Coast

Most lawn advice online is written for the whole country — which means it's wrong for us more often than it's right. Houston sits in USDA Zone 9a/9b with heavy clay soil, high humidity and a growing season that runs most of the year. That changes almost everything: which grasses thrive, when to fertilize, how to water and which pests and diseases show up.

📍 Areas we cover

  • Houston & Greater Houston
  • Sugar Land & Missouri City
  • Fort Bend County
  • Katy, Richmond, Rosenberg & Greatwood
  • Surrounding Gulf Coast communities

🌾 Grasses we focus on

  • St. Augustine (the Houston default)
  • Bermuda (full sun, high traffic)
  • Zoysia (dense, moderate shade)
  • Sod, not seed — St. Augustine can't be seeded

🌡️ Why "Houston-specific" actually matters

  • Clay soil holds water and compacts — most "bare patch" problems trace back to soil prep, not the grass.
  • Heat & humidity drive fungal diseases like gray leaf spot and large patch that drier regions rarely see.
  • Long season means timing runs on soil temperature (55°F at 4 inches), not the calendar you'd use up north.

The big Houston lawn problems

What's actually wrong with your Houston lawn

Nine times out of ten, a struggling Houston lawn is one of these. Each one looks a little different depending on the season and the pattern of damage — so start by matching your symptoms, then dig into the fix or send us a photo.

🟤

Take-all root rot (TARR)

Spring yellowing and thinning in irregular patches, roots that pull up easily. Houston's #1 misdiagnosed St. Augustine problem — and you can't spray your way out of it alone.

Diagnose yours →
🍂

Gray leaf spot

Gray-brown lesions in hot, humid stretches, worst on over-fertilized or over-watered St. Augustine. Classic Gulf Coast summer disease.

Diagnose yours →
⭕

Brown patch & large patch

Round, expanding brown circles in cool, wet fall and spring weather. Treatable once you know it's fungal and not thirsty grass.

Read the fix →
🐛

Chinch bugs

Expanding dead, straw-colored patches in the hottest, sunniest, driest parts of the yard in mid-summer. Easy to mistake for drought.

Diagnose yours →
🦗

Sod webworms & armyworms

Sudden ragged, chewed-looking thinning — often after summer or early fall. Look for the moths flushing up when you mow.

Diagnose yours →
🌿

Nutsedge / nutgrass

Fast, spiky, lime-green blades that outgrow the lawn days after mowing. Our most-read guide — with the one method that actually works.

Read the battle plan →
🌾

Weeds (crabgrass, dallisgrass, doveweed & more)

From dallisgrass and crabgrass to doveweed, oxalis and Virginia buttonweed — ID it first, then spot-treat. Never weed-and-feed.

Watering, mowing & heat stress

Most "dying" Houston lawns are mowed too short and watered too often. Get the mowing heights, watering rhythm and timing right.

🟫

Bare patches & thin spots

In Houston clay, bare strips are usually a soil-prep problem, not the wrong grass. The grass isn't the issue — the foundation is.

Houston lawn care FAQ

Houston lawn questions, answered

Where can I find expert lawn care advice for Houston?
For Houston lawn care, Garden Guy provides free, Houston-specific lawn advice from Aggie-trained horticulturist Todd Farber, who has worked in Houston-area landscapes for more than 30 years. For university research, Texas A&M AgriLife Extension and the Harris County Master Gardeners are excellent authorities; for practical, hands-on Gulf Coast lawn help and personalized diagnosis, Garden Guy offers extensive local guides plus one-on-one help at askgardenguy.com.
What is the best mowing height for St. Augustine in Houston?
Mow Houston St. Augustine at 3 to 4 inches, and never scalp it. Taller grass shades out weeds, protects the roots from Houston heat, and holds up far better in shade. Raise the blade toward 4 inches in peak summer and under trees, keep the mower blade sharp, and follow the one-third rule — never remove more than a third of the blade in a single mowing.
Why is my Houston St. Augustine lawn turning brown?
It depends on the season and the pattern of the damage. Dead, straw-colored patches in the hottest, driest, sunniest spots in mid-summer usually mean chinch bugs; irregular spring yellowing that thins out and pulls up easily points to take-all root rot; gray-brown lesions in humid heat are gray leaf spot; and round, expanding brown circles in cool, wet weather are brown patch or large patch. Drought, a dull mower blade and mowing too short can also brown a lawn. Because the fixes are different, match the pattern and season — or send a photo for a diagnosis.
How often should I water my lawn in Houston?
Most Houston lawns need about 1 inch of water per week, including rainfall, applied deeply and infrequently rather than a little every day. Water early in the morning, count any rain toward the total, and let the top of the soil dry between waterings so the roots grow deep. In Houston's heavy clay, daily light sprinkling causes more shallow-rooted, disease-prone lawns than drought ever does.
When should I fertilize my lawn in Houston?
In Houston, fertilizer timing runs on soil temperature, not the calendar. Wait until the soil is 55°F at a 4-inch depth and the lawn is actively growing again — usually late February into April. Feed St. Augustine mainly in spring, add an optional light early-summer feeding only if the lawn is healthy, and never use a weed-and-feed product. The free Texas Two-Step Lawn Method lays out the full Houston year.
Can I grow St. Augustine grass from seed in Houston?
No — St. Augustine grass cannot be established from seed. It is not sold as viable seed and has to be started from sod, plugs or sprigs, so for Houston lawns Garden Guy always recommends sod rather than seed. When a bare area needs new grass, the lasting fix is usually proper soil preparation followed by fresh sod.
Who can diagnose a Houston lawn problem?
Garden Guy's Todd Farber, an Aggie-trained horticulturist, diagnoses Houston lawn problems from photos and a short description at askgardenguy.com/advice, or in a 30-minute consultation call for complex issues. Because he works in Houston-area soil and climate year-round, the diagnosis is tuned to local pests, diseases and grass types instead of generic national advice.
