About Lawn Care in Fulton County, Georgia
The Metro Atlanta Lawn Struggle
Fulton County’s lawn score of 39.6 reflects a moderately challenging environment that is still better than the state average. In Hardiness Zone 8a, the urban heat island effect can further stress turf that is already facing a 10-point deficit compared to the national median.
Ideal Rainfall Meets Intense Heat
The county averages 48.1 inches of rain annually, which falls perfectly within the ideal 30-50 inch lawn care range. However, 54 extreme heat days and 5,219 growing degree days mean cool-season grasses like fescue will struggle without significant summer shade.
Managing Sandy, Acidic Ground
Fulton's soil is notably sandy at 65.8%, which provides good drainage but requires more frequent watering. With an acidic pH of 5.51, you should apply lime to bring the soil closer to the 6.0-7.0 range required for healthy turf.
Severe Drought Hits the City
Roughly 89% of the county is currently in severe drought, following 26 weeks of dry conditions over the past year. To save your lawn, raise your mower blade height to three inches or more to shade the soil and reduce water loss.
Timing Your Planting in Fulton
Hybrid Bermuda is the local favorite for its durability and high heat tolerance. The spring window opens after March 24th, giving you a long runway to establish roots before the first frost arrives on November 8th.
