About Lawn Care in Coweta County, Georgia
Coweta's Comparative Lawn Advantage
Coweta County’s score of 38.7 makes it easier to manage than the Georgia state average of 35.8. While still below the national median of 50.0, the Zone 8a climate here is more forgiving than in many neighboring counties.
Optimal Rainfall and Milder Heat
The county receives 52.5 inches of rain annually, which is just above the ideal range for lawn health. With only 42 extreme heat days, Coweta lawns face significantly less thermal stress than the state average of 65 days.
Identifying Your Soil's Needs
Specific soil data is not available for Coweta, but regional clay soils often require aeration to prevent compaction. A soil test will help you determine if your lawn needs lime to reach the preferred 6.0-7.0 pH level.
Staying Vigilant During Dry Spells
Although 100% of the county is abnormally dry, only 11% is currently in severe drought. After 26 weeks of drought last year, it is still vital to practice water-wise habits like mulching and maintaining proper mower height.
Spring Planting in Zone 8a
Bermuda and Zoysia are highly recommended for Coweta's climate and soil. Wait for the final frost on April 3 before starting your spring projects to ensure the new grass thrives in the warming soil.

- 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
