Data Story
About Lawn Care in Colorado County, Texas
Thriving in the Coastal Plains
Colorado County enjoys a lawn difficulty score of 39.7, outperforming the Texas state average of 31.7. Located in Zone 9a, the county benefits from a nearly year-round growing cycle, though extreme summer heat remains a primary maintenance factor.
Abundant Rain and Significant Heat
Lawns receive a generous 45.0 inches of annual precipitation, which is well within the ideal range for lush growth. However, a staggering 132 extreme heat days—far exceeding the state average of 105—demands heat-tolerant species that can handle 7,171 growing degree days.
Ideal pH for Nutrient Absorption
The county boasts a soil pH of 6.50, sitting perfectly within the 6.0-7.0 ideal range for plant health. The soil is quite sandy at 57.7%, meaning that while nutrients are easily absorbed, the ground requires consistent organic matter additions to hold moisture.
Severe Drought Risks in the South
Despite high rainfall, the county is currently 100% covered by severe drought (D2+), with 39 weeks of drought over the past year. In these conditions, utilizing rain barrels and drip irrigation for flower beds can help save municipal water for the lawn.
Maximum Growth in a Long Season
The frost-free window begins early on March 9th and extends until late November, offering a massive period for lawn establishment. St. Augustine and Bermuda grass are the local favorites, flourishing in the humid, warm environment of the Texas coastal interior.

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
