About Lawn Care in St. Francis County, Arkansas
Moderate Care in St. Francis County
A lawn difficulty score of 41.5 puts St. Francis County slightly above the Arkansas average for ease of maintenance. While it remains more challenging than the national median of 50.0, the Zone 8a environment is manageable. Success depends on navigating the heavy rainfall and acidic soil conditions.
Managing High Annual Precipitation
St. Francis County receives 51.8 inches of rain per year, which is just above the ideal 50-inch threshold. While specific heat day data is limited, this high rainfall suggests that drainage is a key concern for local lawns. Maintaining a consistent mowing height will help keep the soil surface from staying too damp.
Balancing Clay and Sand Levels
The soil pH in St. Francis County is 5.73, requiring lime to reach the target range of 6.0-7.0. The soil composition is nearly balanced with 20.6% clay and 20.9% sand, providing a mix of nutrient retention and drainage. Regular soil testing is recommended to manage these acidic levels effectively.
Coping with Severe Dry Periods
The county has spent 30 weeks in drought over the last year, with over 54% of the area currently in severe drought (D2+). Homeowners should prioritize deep, infrequent watering to encourage grass roots to grow deeper into the soil. Using drought-tolerant grass varieties can significantly reduce your water dependency.
Starting Strong in Zone 8a
Bermudagrass is a highly recommended choice for this climate due to its natural drought resistance. While local frost dates are variable, most residents find success starting new lawns in late March or early April. Keep a close eye on soil moisture as you establish your new turf.

- 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
