About Lawn Care in Logan County, Arkansas
Logan County outperforms the state lawn average
Logan County earns a lawn difficulty score of 46.5, making it easier to maintain a yard here than the Arkansas average of 37.3. While it remains slightly more challenging than the national median, Hardiness Zone 8a provides a robust environment for many grass types.
Perfect precipitation for steady growth
At 49.7 inches of annual rain, the county sits right at the top of the ideal 30-50 inch range for healthy lawns. With 66 extreme heat days, the climate is slightly warmer than the state average but remains manageable with proper mowing schedules.
Acidic soils require careful balancing
The local soil pH of 5.63 is below the ideal 6.0-7.0 range, suggesting that a lime application may be necessary to improve nutrient uptake. The soil is comprised of 39% sand and 15.7% clay, offering a relatively balanced texture for root development.
Mild drought conditions persist
While the entire county is abnormally dry, only 5.7% of the area currently faces severe drought. Maintaining a higher mowing height during these dry spells can help shade the soil and retain precious moisture.
Optimal planting windows in Zone 8a
Heat-tolerant grasses like Centipede or St. Augustine are well-suited for these conditions. Plan your primary lawn work between the last frost on April 4 and the first fall frost on November 5 to maximize the growing season.

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

Seasonal Breakdown
Wait until after April 4 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 81.3°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 66.15 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 5; this is the best renovation window. Cool winters (January averages 38.9°F) mean slow or dormant growth; keep debris off the lawn.
