Data Story

About Lawn Care in Garland County, Arkansas

Tougher Growing Conditions in Garland

Garland County presents a difficult landscape for turf with a lawn difficulty score of 34.5, falling below both the state average of 37.3 and the national median of 50.0. Located in Zone 8a, your lawn must survive warmer winters and more intense summer heat than northern neighbors. Success here requires a more proactive maintenance strategy compared to most of the country.

High Heat and Heavy Rain

Your grass must endure 71 days of extreme heat over 90°F, surpassing the state average of 64 days. While the 55.6 inches of annual precipitation is generous, it often exceeds the ideal 50-inch limit, which can lead to runoff or fungal issues. High energy levels from 5,247 growing degree days mean your mowing schedule will stay busy from spring through fall.

Navigating Acidic Silt Loams

The soil pH of 5.34 is significantly more acidic than the preferred 6.0-7.0 range, making lime applications essential for a healthy lawn. The texture is a very gravelly silt loam that offers good drainage, but the 16.9% clay content helps retain some moisture during the hot summers. Be prepared to supplement nutrients that are often locked away by high acidity.

Managing Severe Water Shortages

Despite 17 weeks of drought over the last year, the entire county is currently locked in severe drought conditions. With 100% of the area at D2+ levels, water conservation is critical to keep your lawn alive without wasting resources. Utilize mulch in garden beds and avoid fertilizing during these peak stress periods to prevent chemical burn.

Start Early in Zone 8a

For Garland’s Zone 8a climate, heat-tolerant warm-season grasses like Zoysia or Bermuda are your best bets. The growing season typically kicks off after the last spring frost on March 24 and extends until the first frost on November 9. This long window provides plenty of time for established sod to thrive before winter dormancy.

  • 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
