About Lawn Care in Travis County, Texas
Central Texas Heat Tests Travis Turf
Travis County matches the Texas average with a lawn difficulty score of 31.9, though it remains much tougher than the national average of 50.0. This Zone 9a region requires specific strategies to handle intense sun and frequent moisture stress.
Record Heat and High Energy Demand
Lawns must survive 120 extreme heat days per year, which is significantly higher than the state average of 105. While 36.3 inches of rain provides a decent baseline, 7,001 growing degree days mean your mower will stay busy for most of the year.
Neutral pH Meets Heavy Clay Layers
The soil pH is nearly perfect at 7.09, sitting at the top edge of the ideal range for nutrient availability. However, the 32.1% clay content can lead to drainage issues and requires careful management to avoid suffocating lawn roots during heavy rains.
A Year of Constant Severe Drought
Travis County has suffered through 53 weeks of drought in the past year, with 100% of the county currently in a severe drought state. Traditional thirsty lawns are difficult to sustain here without strict adherence to local water restrictions and xeriscaping principles.
Warm-Season Specialists Thrives in Austin
St. Augustine and Zoysia are favored for their ability to handle the 9a climate and Austin's specific soil profile. With the last frost usually passing by March 11, early spring offers the best window to establish roots before the 120-day summer heat wave begins.

- 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
