About Lawn Care in Howard County, Arkansas

Navigating Lawn Care in Howard

Howard County's lawn difficulty score of 35.7 is very close to the Arkansas state average of 37.3, but it remains a tough climb compared to the national median of 50.0. The Zone 8a climate here is characterized by long, hot summers that test the resilience of even the toughest turf. You are working in a region where specialized heat-tolerant care is the standard, not the exception.

Surviving 81 Days of Extreme Heat

Howard County faces a staggering 81 days of extreme heat over 90°F, which is far beyond the state average of 64 days. Although the 55.8 inches of annual rain provides a good base, the 5,614 growing degree days indicate a very high-energy environment that can quickly dry out vegetation. This heat intensity makes irrigation and proper grass selection more critical here than in almost any other part of the state.

Clay and Sand Balance Issues

The local soil is an acidic 5.63 pH, which is slightly below the 6.0-7.0 ideal but manageable with regular lime applications. With 21.0% clay and 48.1% sand, the soil has a decent balance but will still lean toward fast drainage and potential nutrient leaching. Adding organic top-dressing can help bridge the gap and improve the soil's ability to support thick turf.

Severe Drought Across the County

While Howard has seen only 16 weeks of drought over the last year, 94.7% of the county is currently experiencing severe drought conditions. This sudden intensity requires a shift toward water conservation and the use of drought-tolerant grass varieties. Limit heavy traffic on the lawn during these periods to prevent soil compaction and physical damage to stressed grass blades.

Leverage a Long Growing Season

Thanks to a late first frost on November 9 and an early start after March 26, Howard County has a exceptionally long window for lawn growth. Bermuda or St. Augustine grasses thrive in this heat-heavy Zone 8a environment and can handle the 81 days of intense sun better than cool-season alternatives. Start your lawn renovation in April to take full advantage of the peak spring growth spurt.

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
