Planting
Planting a garden in Georgia at the wrong time can mean the difference between a thriving harvest and wasted effort—especially when frost dates shift from mid-March in the mountains to late February in coastal areas.
With 7a-8b zones across the state, timing your 🌱 General Garden becomes a puzzle unless you know the secrets to Georgia’s growing seasons. Cool-season crops like broccoli and lettuce thrive in early spring, while tomatoes and peppers need warmer soil by late April. But what if you miss the window?
I’ve spent years perfecting my schedule, and I’ll show you exactly when to plant each crop—whether you’re in Atlanta’s cooler hills or Savannah’s humid lowlands. No more guessing games, just proven strategies for a garden that delivers.
From frost dates to soil temps, here’s your roadmap to planting like a pro and harvesting like a champion.
Georgia planting zones & frost-free dates: when to start your garden calendar
Georgia’s diverse climate creates unique gardening opportunities, but understanding your USDA planting zone and frost-free dates is critical for success. The Peach State spans zones 7A through 8B, with North Georgia typically cooler (7A-7B) and South Georgia warmer (8A-8B).
These differences dramatically impact when you can safely plant cool-season crops like broccoli versus warm-season favorites such as tomatoes.
Your last frost date marks the transition from winter to spring planting, while the first frost date signals the end of your growing season. In North Georgia, expect your last frost around March 15-30, while South Georgia gardeners often see frost-free conditions by February 28-March 15.
First frosts typically arrive in November, with North Georgia seeing them earlier (mid-November) than South Georgia (late November).
To plan effectively, use the USDA Plant Hardiness Zone Map and local weather data.
For example, Atlanta (Zone 7B) has a shorter growing season than Savannah (Zone 8A), meaning you’ll need to adjust planting times accordingly. Cool-season crops like lettuce and peas thrive in early spring and fall, while warm-season crops such as okra and sweet potatoes need warmer soil temperatures.
For cool-season crops, start seeds indoors 6-8 weeks before your last frost date.
In North Georgia, this means sowing lettuce and spinach by early February, while South Georgia gardeners can wait until late January. Warm-season crops like peppers and eggplants require soil temperatures above 60°F, so wait until after your last frost to plant them outdoors.
If you’re unsure about your exact last frost date, check local weather stations or use the Almanac’s Frost/Freeze Calculator. For example, Athens (Zone 7B) averages a last frost on March 20, while Brunswick (Zone 8A) typically sees frost-free conditions by February 28.
These small differences can mean the difference between a thriving garden and a failed crop.
Pro tip: Use row covers or cold frames to extend your planting window in cooler zones. This allows you to plant cool-season crops like kale as early as February in North Georgia, even if frost is still a risk.
Conversely, in South Georgia, you can push warm-season crops like okra into late summer plantings by using shade cloth to protect young seedlings from intense heat.
Always test your soil temperature before planting. Warm-season crops need soil at least 60°F, while cool-season crops prefer 40-50°F. A simple soil thermometer (available for under $10) will save you from planting too early and risking frost damage.
For example, in Zone 7B, soil may reach 60°F by early April, but in Zone 8A, it could be ready by late March.
Plan your garden calendar by dividing crops into three categories: early spring (plant
Best crops to plant by month in Georgia: month-by-month planting guide
Georgia’s varied climate—from the cooler mountains of North Georgia to the humid lowlands of South Georgia—means your planting schedule should shift based on your location. While Atlanta (Zone 7b) might be ready for tomatoes in early April, Savannah (Zone 8a) could start as early as late February.
The key? Adjusting for your last frost date and soil warmth.
For most of Georgia, spring planting kicks off in February for cold-hardy crops like broccoli and spinach, while warm-season favorites like peppers and sweet potatoes wait until April or May.
Fall planting mirrors this pattern but works backward, with cool-season greens going in August and winter squash planted in September. Let’s break it down month by month.
- 1. February-March: Plant cool-season crops like kale, onions, and peas. North Georgia waits until late March; South Georgia can start earlier.
- 2. April: Warm up soil with black plastic mulch and plant tomatoes, okra, and basil. Wait until soil reaches 60°F+ to avoid stunted growth.
- 3. May-June: Sow southern peas and sweet corn. North Georgia may need row covers for late plantings to protect from late frosts.
- 4. July-August: Direct-sow fall greens like lettuce and radishes for a harvest before first frost. Mulch heavily to retain moisture.
- 5. September: Plant winter squash, broccoli, and carrots. South Georgia can extend this window until early October.
Don’t overlook herbs like cilantro and dill, which thrive in cooler months. In South Georgia, you can even grow winter lettuce year-round with minimal protection. For North Georgia, focus on early spring and late summer plantings to maximize your harvest window.
Pro tip: Use succession planting for bush beans and zucchini every 2–3 weeks to ensure a continuous supply. This works especially well in Georgia’s long growing season, where you can squeeze in two full harvests of many crops.
Remember, soil temperature matters just as much as air temperature. A simple soil thermometer ($10 at garden centers) will save you from planting too early. For warm-season crops, wait until the soil hits 65°F+—this is your green light to start.
