Planting
Planting a garden in Georgia at the right time means the difference between a thriving harvest and a total loss to frost or heat.
Georgia’s humid subtropical climate means your garden’s success hinges on planting at the right time—too early and frost kills tender starts, too late and summer’s heat wipes them out.
With 7b to 8b USDA zones and 210 frost-free days, timing is everything. Whether you’re growing heat-loving tomatoes or cool-season greens, this guide breaks down the best months to plant for your region.
Discover the exact planting windows for spring and fall crops, how to adjust for Atlanta’s cooler microclimate vs. Savannah’s longer growing season, and the 3 key mistakes that ruin timing every year.
Georgia’s planting zones & best months for heat-tolerant crops
Georgia spans USDA Zones 7a through 8b, meaning your planting schedule should account for both early spring frosts (as late as March) and sweltering summer heat (peaking in July-August).
Heat-loving crops like tomatoes, peppers, and okra thrive when planted after the last frost, but timing varies by zone—Zone 7a (northern GA) has a shorter window than Zone 8b (coastal GA).
For tomatoes, peppers, and squash, the sweet spot is April through early June, but okra—Georgia’s ultimate heat-lover—can handle direct sowing in May once soil temps hit 70°F+.
If you’re in Zone 8b, you might even squeeze in a fall planting of heat-tolerant crops like black-eyed peas in August.
Here’s how to adjust for early/late frosts: Use row covers for March plantings in Zone 7a, and monitor local frost alerts via the UGA Extension website. In Zone 8b, you can push fall crops until October 1st—just be ready to harvest before frost.
| Crop | Zone 7a (North GA) | Zone 7b-8a (Central GA) | Zone 8b (Coastal GA) | Notes |
|---|---|---|---|---|
| Tomatoes | April 15–May 15 | April 1–May 30 | March 15–June 15 | Start indoors 4–6 weeks before last frost; use cage support. |
| Peppers | April 20–May 10 | April 1–May 20 | March 20–June 10 | Transplant after soil warms to 65°F+; mulch to retain heat. |
| Squash | May 1–June 1 | April 15–May 30 | April 1–June 15 | Direct sow after last frost; thin to 2–3 plants per hill. |
| Okra | May 15–June 15 | May 1–June 30 | April 15–July 15 | Plant only after soil hits 70°F+; harvest pods 3–4 inches long. |
| Fall Adjustments | August 1–September 15 | July 15–September 30 | June 15–October 15 | Use row covers for late-season crops like collards. |
In Zone 7a, where frosts linger until mid-April, I recommend starting tomato and pepper seeds indoors in February to give them a head start. For Zone 8b, you can direct-sow okra in April—it’s so heat-tolerant that it’ll outlast most summer crops.
Always check soil temperatures with a soil thermometer; peppers need 65°F+, while squash thrives at 70°F+.
Pro tip: If you’re in Zone 7b or 8a (like Atlanta or Macon), you can double-crop by planting fast-maturing varieties like bush beans in late May after harvesting early spring greens. This maximizes your garden’s productivity in Georgia’s short but intense growing season.
For okra, which is a staple in Southern gardens, I swear by direct sowing in May—no need for transplants. Just scratch seeds into well-drained soil, water deeply, and watch them bolt into growth within weeks.
If you’re in Zone 8b, you can even plant a second crop in July for a fall harvest.
Don’t forget to mulch heavily in
How to extend your Georgia growing season for fall/winter crops
Georgia’s warm winters and mild falls let you grow cool-season crops like kale, spinach, and carrots well into December—if you use the right tricks. The key is protecting tender plants from light frosts (28-32°F) while giving them enough sunlight to thrive.
I’ve tested these methods in Zone 7b-8a and they’ve doubled my harvest window!
Start by planting cool-season crops in early October for a November harvest. These include broccoli, Brussels sprouts, and leaf lettuce, which tolerate light frosts and even taste sweeter after a light freeze.
For spinach and kale, you can push it even later—some varieties handle 20°F with protection!
Here’s my go-to strategy: Use floating row covers (like Reemay fabric) to shield plants from 30°F+ frosts. These let sunlight and water through while blocking wind chill.
For hardier crops like cabbage or radishes, a simple hoop tunnel with clear plastic extends harvests until January in most of Georgia.
A cold frame (a clear plastic box over plants) is another game-changer. It traps heat during the day and protects against frost at night. I’ve grown baby carrots and turnips straight through December using this method.
Just ventilate daily to prevent overheating—lift the lid on sunny days to avoid scorching tender leaves.
Don’t forget succession planting! Sow fast-growing crops like radishes or lettuce every 2-3 weeks in September and October. This ensures a steady harvest even as temperatures drop. Pair them with slow growers like cabbage or broccoli for a balanced fall garden.
For maximum protection, combine row covers with black plastic mulch in November. The mulch insulates soil, keeping roots 10°F warmer than bare ground. This lets you grow garlic and onions through winter—just plant them in October for a spring harvest.
Monitor your local frost dates (UGA Extension provides free frost maps for Georgia). In northern GA (Zone 7a), first frosts hit mid-November, while southern GA (Zone 8a) may see frosts as late as January.
Adjust your planting timeline accordingly—cool crops need 60-70 days to mature, so time it right!
