Data Story
About Lawn Care in Tattnall County, Georgia
Tattnall County is a High-Difficulty Zone
With a score of 22.3, Tattnall County is one of the more challenging places in Georgia to grow a lawn. This score is significantly tougher than the state average of 35.8 and less than half the national median of 50.0. The jump to Hardiness Zone 9a introduces unique heat and humidity pressures.
Intense Heat and Long Growing Seasons
This county endures 92 extreme heat days per year, far exceeding the state average of 65. Combined with 6,266 growing degree days, grass grows aggressively and requires frequent maintenance. The 49.8 inches of annual rain barely keeps up with the high evaporation rates caused by July's 81.9°F average.
Overcoming Soil Limitations through Testing
Specific soil data for Tattnall is unavailable, but the high heat suggests a need for soil that retains moisture without becoming waterlogged. Aim for a pH between 6.0 and 7.0 by testing your soil before the spring growing season begins. Adding organic matter can help stabilize the foundation for your turf.
Bracing for Chronic Severe Drought
Tattnall has spent 34 weeks in drought over the last year, and 100% of the county currently sits in a Severe Drought (D2+). This is much higher than neighboring counties and requires a very disciplined irrigation strategy. Focus on keeping the roots hydrated during the relentless 92 days of extreme heat.
Zone 9a Favorites for Tattnall Lawns
St. Augustine and Bahia grass are excellent choices for the warm Zone 9a climate and long summer. The growing season can safely start after the early March 9th frost, giving you a head start on the state's average schedule. You have until late November before the first fall frost signals the end of the growth cycle.

- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
