Local data

Why this date changes by ZIP

Atlanta frost history and USDA zone 8a shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

University of Georgia Extension is the kind of local source to verify against when a crop is expensive, weather is unusual, or your yard has a cold pocket.
