About Lawn Care in Harrison County, Texas
Average Difficulty in East Texas
Harrison County's lawn difficulty score of 30.4 nearly matches the Texas state average of 31.7. This 8b hardiness zone offers a more manageable environment than the coast, though it still poses challenges compared to the national median.
Optimal Rain for East Texas Lawns
The county's 51.0 inches of annual precipitation is near the top of the ideal range for turf health. While there are 89 extreme heat days, the 5,929 growing degree days provide a balanced pace of growth for residential yards.
Sandy Terrain Requires Acid Adjustment
The soil is notably sandy at 58.3%, which aids in drainage but may lead to rapid drying. With a pH of 5.28, you will likely need to apply lime to bring the soil closer to the neutral range preferred by most turfgrasses.
Severe Drought Affects Most Areas
Currently, 63.1% of Harrison County is under severe drought conditions after 19 weeks of drought this past year. Regular organic top-dressing can help your sandy soil retain moisture during these increasingly common dry spells.
Start Planting in Mid-March
Centipedegrass and Carpetgrass are popular for East Texas because they tolerate the acidic, sandy conditions found here. Mark March 20 on your calendar as the safe date to begin seeding or sodding for the season.

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

Common Lawn Problems in Harrison County
Excess Moisture & Fungal Disease
High annual rainfall (51 inches) increases risk of fungal diseases like brown patch and dollar spot. Ensure good drainage and avoid overwatering.
Acidic Soil
Soil pH of 5.3 is below the ideal range for most grasses (6.0-7.0). Apply agricultural lime to raise pH gradually.
