Data Story
About Lawn Care in Little River County, Arkansas
Managing the heat in Little River County
With a lawn difficulty score of 36.7, homeowners here face a significantly steeper challenge than the national median of 50.0. This region sits in USDA Hardiness Zone 8b, where warm-season grasses typically thrive but require careful management to withstand the local climate.
High heat days demand consistent hydration
The county experiences 83 extreme heat days annually, far exceeding the state average of 64 days. While the 53.7 inches of annual precipitation is slightly above the ideal range, the intense summer sun and 5,505 growing degree days can quickly dry out thirsty turf.
Testing is key for unknown soil profiles
Specific local soil data for pH and texture is currently unavailable for this county. Local growers should conduct a soil test to determine if they need lime or specific nutrients before the peak growing season begins.
Severe drought impacts nearly the whole county
Currently, 95% of the area is under severe drought conditions, and the county has endured 11 weeks of drought over the past year. To protect your lawn, prioritize deep, infrequent watering during the early morning hours to minimize evaporation.
Start your Zone 8b lawn this spring
Bermuda and Zoysia are excellent choices for this climate, as they tolerate heat better than cool-season varieties. Aim to seed or sod after the last spring frost on March 24 but well before the first fall frost on November 11.

- 3EstablishOct 15 – Nov 11
Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.
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

Seasonal Breakdown
Wait until after March 24 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 82.2°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 82.7 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 11; this is the best renovation window. Mild winters (January averages 42.7°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
Little River County receives abundant rainfall (53.7 inches annually), so lawns rarely need supplemental irrigation. 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.
