About Lawn Care in Hempstead County, Arkansas

A Strong Start for Hempstead Lawns

Hempstead County earns a lawn difficulty score of 41.3, making it one of the easier places in Arkansas to keep a yard green. This score sits well above the state average of 37.3, though it trails the national median of 50.0. The local Zone 8a climate provides a long, warm season that is conducive to vigorous grass growth.

Navigating 70 Days of Sun

Homeowners must manage 70 extreme heat days each year, slightly higher than the state average of 64 days. With 55.1 inches of annual precipitation, the county receives more than enough water, though heavy rains can sometimes leach nutrients from the soil. The 5,402 growing degree days mean your lawn will be extremely active and require regular mowing from spring to late autumn.

Rapid Drainage in Fine Sand

Your lawn grows in fine sand that is classified as somewhat excessively drained, meaning water moves through the root zone very quickly. The pH of 5.83 is quite close to the ideal range of 6.0-7.0, reducing the need for heavy lime applications. However, the high sand content (43%) and low clay (22.8%) suggest you should apply fertilizer in smaller, more frequent doses to prevent runoff.

Managing Moderate Drought Stress

Hempstead has seen only 14 weeks of drought over the past year, and currently, only 22.1% of the county is in severe drought. This makes it more resilient than many neighboring regions, but the sandy soil still poses a risk of quick drying. Using smart irrigation controllers can help you manage the excessively drained soil without wasting water.

Maximize the Zone 8a Season

Bermuda and St. Augustine grasses are excellent choices for Hempstead's Zone 8a heat and sandy textures. Your growing season begins after the last frost on March 26 and doesn't end until November 6, providing over seven months of prime growth. Start your lawn projects in mid-April to ensure the soil is warm enough for fast root establishment.

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

Seasonal Breakdown

Summers are warm (July averages 81.5°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 70.4 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 6; this is the best renovation window. Mild winters (January averages 42.4°F) allow year-round mowing for warm-season lawns and minimal dormancy.

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.
