Mild Summers Help Grass Thrive

Your lawn will likely stay green longer into the summer here than in the hotter southern counties.
Near-Perfect Soil Chemistry
The soil pH in Fulton County is a healthy 6.55, which is virtually perfect for standard grass nutrition. It contains 23.0% clay and 15.8% sand, a combination that balances moisture storage with essential drainage. You likely won't need many soil amendments to see great results.
Total County Under Severe Drought
Currently, 100% of Fulton County is experiencing severe drought conditions, and the area has seen 34 drought weeks in the past year. This level of dryness is a significant challenge even for the best soils, making supplemental watering a necessity. Watch for signs of wilting and water deeply to protect the turf through this extreme period.
Ready for Spring After Late April
The last spring frost usually occurs around April 22, so wait until then to start sensitive lawn work. Kentucky Bluegrass is a favorite here and performs well given the mild summer temperatures. Use the long fall season starting around October 19 to overseed any thin spots.
