Ideal Rainfall Meets Summer Heat
The county receives 40.5 inches of annual precipitation, which falls perfectly within the ideal range for healthy turf. While residents face 82 extreme heat days over 90°F, the 5,701 growing degree days support a robust, active growing season.
Managing Sandy Alkaline Soils
Soil here is roughly 52.6% sand, which helps with water movement but may require more frequent nutrient monitoring. With a pH of 7.17, the ground is slightly more alkaline than the ideal 6.0-7.0 range, often benefiting from sulfur amendments to lower acidity.
Weathering Moderate Dry Spells
Cooke County spent 18 weeks in drought over the last year, and currently, the entire area is abnormally dry. Homeowners should focus on deep, infrequent watering to encourage deep root systems before the next severe dry spell hits.
Timing Your North Texas Turf
Bermudagrass and Zoysia thrive in this 8a zone once the threat of frost passes after March 19. Aim to establish new sod or seed in late spring to capitalize on the 5,701 growing degree days available before the first November frost.

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

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
