About Lawn Care in Houston County, Texas
Moderate Lawn Challenges in East Texas
With a difficulty score of 38.1, Houston County presents an easier landscape than the Texas average of 31.7, though it remains more challenging than the national median of 50.0. The local climate falls within USDA Hardiness Zone 8b, which supports a wide variety of heat-tolerant turfgrasses. Homeowners here benefit from a more forgiving environment than many of their neighbors to the west.
Wet Climate Meets High Heat
The county receives a generous 47.3 inches of annual precipitation, which aligns well with the ideal lawn range of 30-50 inches. However, 103 extreme heat days and 6,411 growing degree days mean turf must endure significant thermal stress. High moisture levels combined with heat can accelerate growth but also increase the risk of fungal diseases.
Acidic Sands Require Careful Balancing
Local soils are notably acidic with a pH of 5.77, falling below the ideal 6.0-7.0 range for most standard turfgrasses. The composition is 54.8% sand and 17.4% clay, which suggests rapid drainage but poor nutrient retention. Periodic lime applications are typically necessary to raise the pH and improve nutrient uptake for a lush green look.
Severe Drought Risks Persist
Despite high annual rainfall, 95.3% of the county currently faces severe drought conditions, having spent 20 weeks in drought over the past year. Maintaining a lawn during these periods requires deep, infrequent watering early in the morning to minimize evaporation. Using rain barrels can help bridge the gap when 100% of the area is classified as abnormally dry.
Start Your Lawn This Spring
Bermuda and Zoysia are excellent choices for Zone 8b as they tolerate the high local heat and acidic sandy soil. Aim to seed or sod after the last spring frost on March 13 to give roots time to establish before the summer heat peaks. With the first fall frost arriving around November 17, the growing window is long and productive.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- Start irrigation if rainfall is below 1 inch/week
- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Raise mowing height to reduce heat stress
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Overseed with ryegrass for winter color
