Data Story
About Lawn Care in Gregg County, Texas
Managing the East Texas Heat
Gregg County scores a 36.8 for lawn difficulty, placing it ahead of the state average of 31.7. In hardiness zone 8b, your lawn will face a long, warm season that requires consistent maintenance and mowing.
Abundant Rainfall Supports Growth
The county receives a generous 48.0 inches of rain annually, which is at the top of the ideal range for most turf. This high rainfall helps offset the 103 extreme heat days that can otherwise stress the grass.
Adapting to Local Soil Needs
While specific soil data is unavailable for this county, regional East Texas soils often tend toward acidity. It is highly recommended to perform a local soil test to determine if you need to add lime to reach the ideal pH range.
Managing Moderate Drought Risks
Gregg County faced 13 weeks of drought over the past year, but currently lacks severe drought conditions. During drier periods, mulching your grass clippings can help retain soil moisture and protect roots from the heat.
Start Strong in Early March
Bermuda and Centipede grass are popular choices that love the local humidity and 8b climate. Start your seeding or sodding projects after March 8 to take advantage of the wet, warming spring weather.

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
