What Garden Zone is Atlanta?

Atlanta is primarily in USDA Hardiness Zones 8a and 8b, according to the 2023 USDA Plant Hardiness Zone Map. This means Atlanta's average annual minimum winter temperatures fall between 10°F and 20°F. The 2023 update shifted most of Atlanta up from the previous designation of 7b/8a, reflecting warmer winter temperatures based on 30 years of weather data.

While hardiness zones help you choose perennials, shrubs, and trees that can survive Atlanta winters, they only tell part of the story. These zones don't account for Atlanta's humid summers, red clay soil, unpredictable late spring frosts (typically ending in late March to early April), or summer heat that can stress certain plants.

For Atlanta gardeners, success depends on more than just your zone number. You need to understand our specific growing seasons—when to plant cool-season crops like kale and lettuce versus heat-lovers like tomatoes and peppers. Working with a local garden consultant who understands Atlanta's unique combination of zone, climate, soil conditions, and microclimates ensures you choose the right plants and timing for a thriving garden.
