About Lawn Care in Calhoun County, Mississippi

Calhoun County's Tough Lawn Climate

Calhoun County is one of the toughest spots for lawns in Mississippi, with a difficulty score of 23.9. This score is significantly lower than the state average, reflecting the complex mix of soil and drought challenges in the area.

Steady Growth in Zone 8a

The county receives 58.4 inches of rain annually and sees 63 days of extreme heat. These factors contribute to 5,506 growing degree days, creating a long, active season where grass thrives if properly hydrated.

Silt Loam and Drainage Hurdles

The soil is classified as silt loam and is generally somewhat poorly drained, which can lead to standing water. Combined with an acidic pH of 5.18, homeowners will need to focus on both drainage improvements and lime amendments.

Persistent Drought Exposure

With 29 weeks spent in drought over the last year, 76.4% of the county currently remains abnormally dry. In these conditions, it is vital to avoid over-fertilizing, as salt buildup can further stress thirsty grass.

Planting Around the Late March Frost

For best results in Calhoun County's silt loam, consider hardy warm-season grasses that can tolerate wet feet. Wait until after the March 28 frost date to ensure your new lawn isn't damaged by a late-season cold snap.

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
