Georgia spans USDA zones 7a through 9a with hot, humid summers and mild winters. Discover styles that thrive in the Peach State's red clay, from classic Southern cottage gardens to modern native plantings.
Georgia has a humid subtropical climate with long, hot summers averaging 90+ F and mild winters rarely dropping below 20 F. The state receives 45-55 inches of rain annually. Mountain regions in the north are cooler, while the coastal plain and Savannah area are warmer and more humid.
Dense red clay soils that hold water in winter and crack in summer drought
Extreme summer humidity promoting powdery mildew, black spot, and root rot
Intense heat stress on cool-season plants and even some warm-season species
Kudzu, privet, and other aggressive invasives outcompeting native plants
Work organic matter into Georgia red clay annually to improve both drainage and water retention
Choose heat-tolerant cultivars of popular plants — oakleaf hydrangea over bigleaf hydrangea, for example
Provide afternoon shade for plants that wilt in Georgia's intense summer sun
Water at the base of plants in early morning to reduce fungal disease pressure from humidity
よくある質問
01 What are the best plants for Georgia gardens?
Georgia classics include oakleaf hydrangea, flowering dogwood, azaleas, crepe myrtles, and Southern magnolia. Native beautyberry and coreopsis add seasonal color. For the coast, consider palmettos, camellias, and live oaks that handle salt and humidity.
02 When should I plant in Georgia?
Fall (October-November) is Georgia's best planting season — mild temperatures and winter rain help roots establish before summer stress. Spring (March-April) is the second window. Avoid planting in June-August when heat and drought stress are at their peak.
03 How do I improve Georgia red clay soil?
Add 3-4 inches of composted pine bark, leaf mold, or aged compost to the top 6-8 inches of soil annually. Don't add sand — it creates a concrete-like mixture with clay. Use raised beds for vegetables and choose clay-adapted plants like coneflower, coreopsis, and native grasses.
