Data Story
About Lawn Care in Winston County, Mississippi
Average Lawn Difficulty in Winston
Winston County’s lawn difficulty score of 30.5 sits right at the Mississippi state average of 30.9. While manageable, it remains more difficult than the national median of 50.0. The Zone 8a climate provides a standard challenge for warm-season turf.
Managing Moderate Heat and High Rain
The county experiences 66 extreme heat days, which is slightly better than the state average of 73. However, the 58.9 inches of annual rain can lead to runoff and nutrient leaching. Homeowners must balance their fertilization with these heavy rainfall events.
The Challenge of Highly Acidic Soil
Winston has a very low soil pH of 4.94, well below the ideal 6.0 range for most grass types. With 43.3% sand and 15.8% clay, the soil is prone to losing nutrients quickly. Significant lime application is required to neutralize the acidity and foster healthy grass.
Currently Navigating Abnormally Dry Soil
While Winston only saw 5 weeks of drought last year, 72.8% of the county is currently classified as abnormally dry. This sudden shift means residents should keep their watering systems ready. Monitoring soil moisture is key to preventing grass from entering early dormancy.
Seeding After the March Frost
The growing season begins after the final frost on March 21 and ends in mid-November. Bermuda and Zoysia grasses are the best options for this Zone 8a climate. Ensure you apply lime early in the spring to help your grass take advantage of the 5655 growing degree days.

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
