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

Lawn Care Advisory: Howard County
Lawn Verdict
Howard County falls in USDA hardiness zone 8a, a favorable range for both cool- and warm-season grasses. with winter lows reaching around 10.0°F. and 5,614.4 growing degree days annually, supporting vigorous warm-season lawns. High annual precipitation (55.8 inches) supports lush growth but increases disease pressure.
Seasonal Breakdown
Wait until after March 26 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 82.4°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 81.3 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 9; this is the best renovation window. Mild winters (January averages 42.9°F) allow year-round mowing for warm-season lawns and minimal dormancy.
Watering Guidance
Howard County receives abundant rainfall (55.8 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.
