Data Story

About Lawn Care in Stone County, Mississippi

Tough Conditions on the Coastal Plain

With a difficulty score of 17.8, Stone County is one of the most challenging places in the country to maintain a pristine lawn. The environment is significantly harsher than the state average of 30.9, largely due to the intense Zone 9a heat and sandy terrain.

Extreme Heat and Record Rainfall

The county endures 84 extreme heat days per year, well above the state average of 73 days. This heat is coupled with a massive 67.4 inches of annual precipitation, creating a tropical environment that demands heat-tolerant grass species and frequent fungal monitoring.

Sandy Ground and Acidic Baselines

The soil profile is 61.6% sand and only 10.5% clay, leading to very rapid drainage that can leave roots thirsty despite high rainfall. A low pH of 5.00 means heavy lime applications are essential to make soil nutrients available to your grass.

Extended Drought Despite Heavy Rains

Despite high total rainfall, the county spent 23 weeks in drought last year, and 100.0% of the area currently remains abnormally dry. Mulching grass clippings back into the lawn is vital here to help retain moisture in the porous, sandy soil.

Target the Long Growing Season

St. Augustine and Bahiagrass are the best performers for the high heat of Zone 9a and the local sandy soil. Your primary growing window opens after March 14 and extends until the first frost on November 18.

    Prepare the seedbedMar 13 – Mar 26

    Mow low, dethatch or rake, and loosen the top ½ inch of soil so seed makes good contact.

  3. 3
    EstablishApr 25 – May 22

    Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.

Watering while it germinatesSand soil

Sandy soil drains fast — water lightly and often. Aim to keep the top 1 inch moist with 2–3 short cycles a day (~0.1 in each) until germination, then taper to deeper, less frequent watering.

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
