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.

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

Acidic Soil
Soil pH of 5.0 is below the ideal range for most grasses (6.0-7.0). Apply agricultural lime to raise pH gradually.
Persistent Drought Conditions

Seasonal Breakdown
Wait until after March 14 to seed or overseed; soil temperatures should consistently reach 50-55°F. Summers are warm (July averages 80.9°F); monitor for heat stress and water when soil is dry 2-3 inches down. With 83.7 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 18; this is the best renovation window. Mild winters (January averages 48.9°F) allow year-round mowing for warm-season lawns and minimal dormancy.
