About Lawn Care in Falls County, Texas
Falls County Lawn Maintenance Overview
Falls County earns a lawn difficulty score of 45.6, placing it slightly below the national median of 50.0 but significantly ahead of the Texas state average of 31.7. Homeowners in Hardiness Zone 8b face moderate challenges in balancing heat with moisture. While easier than many neighboring counties, keeping a lush lawn here still requires consistent attention to local conditions.
Managing Heat and Humidity
The county receives 39.1 inches of annual precipitation, which sits comfortably within the ideal range for healthy turf. However, with 102 extreme heat days over 90°F and 6,146 growing degree days, grass can quickly scorch without careful monitoring. The high July average of 82.9°F necessitates a rigorous watering schedule during the peak of summer.
Working with Loamy Soil
The soil here is a well-drained loam with a pH of 7.23, which is slightly more alkaline than the ideal 6.0 to 7.0 range. A clay content of 31.3% helps retain moisture, though it may require aeration to prevent compaction. Most lawns benefit from sulfur-based amendments to slightly lower the pH for better nutrient uptake.
Current Water and Drought Status
With 18 weeks spent in drought over the last year, 100% of the county currently experiences abnormally dry conditions. Residents should practice deep, infrequent watering to encourage deep root growth and minimize evaporation. Maintaining a taller mowing height helps shade the soil and conserve the moisture already present.
Best Practices for Your 8b Lawn
Bermudagrass and Zoysia are the top choices for this climate due to their heat tolerance and resilience. Aim to seed or sod after the last spring frost on March 21 to give the roots time to establish before the summer heat. With a long growing season that lasts until the first frost on November 9, your lawn has plenty of time to thrive.

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
- Overseed with ryegrass for winter color

Lawn Care Advisory: Falls County
Lawn Verdict
Falls County falls in USDA hardiness zone 8b, a favorable range for both cool- and warm-season grasses. with winter lows reaching around 15.0°F. and 6,145.7 growing degree days annually, supporting vigorous warm-season lawns. Moderate rainfall (39.1 inches) generally supports healthy lawns with minimal supplemental watering.
Seasonal Breakdown
Wait until after March 21 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 82.9°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 102.1 days above 90°F annually, warm-season grasses recover faster from summer stress than cool-season types. Aerate and overseed cool-season lawns by early fall, well before November 9; this is the best renovation window. Mild winters (January averages 46.3°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
With 39.1 inches of annual rainfall, established lawns typically need watering only during extended dry spells. Currently, 100.0% of the county is in moderate drought according to the US Drought Monitor. Consider reducing irrigation frequency and allowing cool-season lawns to go semi-dormant during peak heat. Standard warm-season watering of 1 inch per week is usually adequate during summer. High heat accumulation means warm-season grasses use water aggressively — monitor soil moisture regularly.
