About Lawn Care in Arkansas County, Arkansas
Managing the Arkansas County Landscape
Arkansas County holds a lawn difficulty score of 34.9, trailing both the state average of 37.3 and the national median of 50.0. The local 8b hardiness zone allows for a wide range of warm-season grasses but requires diligent care during temperature swings.
Heat and Rain Driving Lawn Growth
With 51.7 inches of annual precipitation, the county sits just above the ideal 30-50 inch range for lawn health. The 66 days of extreme heat exceeding 90°F demand a consistent watering schedule to prevent turf dormancy.
Working with Silt Loam Soil
The local soil is a moderately well-drained silt loam with a pH of 5.83, slightly below the ideal 6.0-7.0 range. Adding a touch of lime can help neutralize the acidity and improve nutrient uptake for your grass.
Combatting 30 Weeks of Drought
The county has faced 30 weeks of drought over the last year, and 55.4% of the area currently experiences severe conditions. Water deeply and infrequently to encourage deep root growth that survives these prolonged dry spells.
Planting for Success in Zone 8b
Bermuda or Zoysia grasses are ideal for this climate and should be established after the last frost on March 11. Start your prep now to ensure a lush, green carpet before the summer heat arrives.

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: Arkansas County
Lawn Verdict
Arkansas 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 5,544.767 growing degree days annually, supporting vigorous warm-season lawns. High annual precipitation (51.7 inches) supports lush growth but increases disease pressure.
Seasonal Breakdown
Wait until after March 11 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 81.6°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 65.5 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 17; this is the best renovation window. Mild winters (January averages 42.1°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
Arkansas County receives abundant rainfall (51.7 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.
