Lawn timing geography of Georgia
Across the 126 Georgia locations with complete 1991–2020 frost
normals, the average last spring frost — the anchor for pre-emergent and spring
work — ranges from Feb 8 (Brunswick) to Apr 26
(Blairsville Exp Stn), a spread of about 11 weeks driven by elevation, latitude, and terrain.
The same job can be weeks apart at opposite ends of the state, which is why a
state-level date is only a starting point — pick the location nearest your yard and
plan from its calendar.
The Georgia lawn year in one paragraph
The Georgia lawn year lives in the warm months: pre-emergent in late winter before soil crosses 55°F, establishment and the first feeding after full green-up, aeration in the heat of active growth, and steady mowing all summer. The discipline that separates good southern lawns is the stop date — no nitrogen within 6–8 weeks of first frost, so the lawn hardens off and goes dormant on schedule. Details by task: when to overseed in Georgia, when to aerate in Georgia, when to apply crabgrass pre-emergent in Georgia, and more above.
