Data Story

About Lawn Care in Clay County, Arkansas

A Strong Start in Clay County

With a lawn difficulty score of 40.0, Clay County is actually easier to maintain than the state average of 37.3. Though it still trails the national average of 50.0, the Zone 7b climate offers a more temperate environment for various grass types.

Ideal Rainfall for Easy Growth

Clay County receives 49.9 inches of rain annually, which hits the sweet spot of the 30-50 inch ideal range perfectly. With only 54 extreme heat days, turf here avoids the worst of the summer scorch seen in southern Arkansas.

Well-Drained Silt Loam Advantage

Your lawn likely sits on well-drained silt loam, a high-quality texture for growing healthy turf. However, the pH of 5.69 is slightly acidic, so testing your soil for lime requirements is a smart first step.

Total Coverage Severe Drought

While the climate is usually mild, 100% of the county is currently under severe drought conditions. Following 30 weeks of drought over the past year, using rain barrels and drought-resistant seeds is critical for long-term resilience.

Seeding for Success in Zone 7b

The window for seeding opens after the March 27 frost and remains favorable throughout the summer. Consider tall fescue for its resilience or Bermuda grass to take advantage of the 4,852 growing degree days available.
