Cabbage in Georgia grows best when planted for a spring harvest, timing it to mature before the state’s hot summer weather sets in. Knowing exactly when to plant cabbage in Georgia is the key to getting firm, sweet heads instead of bitter, bolted ones. Georgia’s climate is tricky—mild winters but quick, intense heat—so you need a clear plan.
This guide covers everything from soil temperature to frost dates. You’ll get the exact planting windows for both spring and fall crops. Let’s break it down so you can start your cabbage seeds with confidence.
When To Plant Cabbage In Georgia
The best time to plant cabbage in Georgia depends on where you live. North Georgia (mountains) runs cooler than South Georgia (coastal plain). Your planting dates shift by about two to three weeks depending on your zone.
Spring Planting Window
For a spring harvest, you want cabbage to mature before daytime highs regularly hit 80°F. Cabbage stops forming heads when it gets too hot. It also turns bitter and may bolt (send up a flower stalk).
- North Georgia (Zones 6b-7a): Start seeds indoors 6-8 weeks before last frost. Transplant outdoors 2-3 weeks before last frost. Typical transplant dates: March 15 to April 1.
- Central Georgia (Zones 7b-8a): Start seeds indoors mid-January to early February. Transplant outdoors late February to mid-March.
- South Georgia (Zones 8b-9a): Start seeds indoors late December to early January. Transplant outdoors late January to mid-February.
Check your local frost dates. The last spring frost in Georgia ranges from late March (south) to mid-April (north). Cabbage seedlings can handle light frosts, but hard freezes below 26°F can damage them.
Fall Planting Window
Fall cabbage is often sweeter because it matures in cooler weather. You plant it in late summer for a harvest before the first hard freeze. Timing is reversed—you want heads to form as temperatures drop.
- North Georgia: Direct seed or transplant from July 15 to August 1. Harvest October to November.
- Central Georgia: Transplant from August 1 to August 15. Harvest November to December.
- South Georgia: Transplant from August 15 to September 1. Harvest December to January.
Fall cabbage often stores longer than spring cabbage. It also faces fewer pest problems because the worst cabbage worms fade by October.
Soil Temperature And Germination
Cabbage seeds germinate best when soil temperature is between 45°F and 85°F. The sweet spot is 70°F. If the soil is too cold (below 40°F), seeds rot. Too hot (above 90°F), germination fails.
Use a soil thermometer to check. For spring planting, you can warm the soil by covering it with black plastic for a week before transplanting. For fall planting, shade the soil or water it deeply to cool it down.
Ideal Soil Conditions
- pH between 6.0 and 6.8
- Well-draining, loamy soil
- Rich in organic matter (compost or aged manure)
- Consistent moisture—cabbage is 92% water
Test your soil pH before planting. Georgia’s red clay is often acidic. Add lime if needed to raise pH. Cabbage hates acidic soil—it stunts growth and invites clubroot disease.
Starting Cabbage Indoors
Most Georgia gardeners start cabbage indoors to get a head start on the season. Direct seeding is possible for fall crops, but spring direct seeding often fails because the soil stays too cold or wet.
Step-By-Step Indoor Seeding
- Fill seed trays with sterile seed-starting mix.
- Sow seeds ¼ inch deep, 2 seeds per cell.
- Water gently from the bottom.
- Place under grow lights or in a bright south window.
- Keep soil temperature at 65-70°F.
- Thin to one seedling per cell after true leaves appear.
- Harden off seedlings for 7-10 days before transplanting.
Hardening off is critical. Move seedlings outside for a few hours each day, gradually increasing exposure. This prevents transplant shock. Without hardening off, your cabbage may wilt or die after planting.
When To Start Seeds Indoors
Count backward from your transplant date. Cabbage seedlings need 6-8 weeks indoors. If you transplant on March 15, start seeds around January 20. For fall crops, start seeds 4-6 weeks before transplant date.
Don’t start too early. Overgrown seedlings (taller than 6 inches) transplant poorly. They become leggy and produce small heads. Aim for stocky, 4-inch seedlings with 4-5 true leaves.
Transplanting Cabbage Outdoors
Transplant on a cloudy day or in late afternoon to reduce stress. Water the seedlings well an hour before moving them. Dig holes slightly deeper than the root ball.
Spacing Requirements
- Standard heads: 18-24 inches apart in rows 24-36 inches apart
- Small varieties (like ‘Early Jersey Wakefield’): 12-18 inches apart
- Large varieties (like ‘Stonehead’): 24-30 inches apart
Closer spacing produces smaller heads. Wider spacing gives larger heads. For a family garden, 18 inches is a good compromise. You can also plant in a grid pattern to maximize space.
Frost Protection
Cabbage is cold-hardy but not invincible. Young transplants can survive light frosts (28-32°F). Hard freezes (below 26°F) kill them. Use row covers or cloches if a late freeze is forecast.
Row covers also protect against cabbage worms and flea beetles. They let in light and water but block pests. Remove them when temperatures exceed 80°F to prevent overheating.
Direct Seeding Cabbage
Direct seeding works best for fall crops. The soil is warm, and you avoid transplant shock. For spring, direct seeding is risky because the soil stays cold and wet, leading to poor germination.
How To Direct Seed
- Prepare the bed by removing weeds and adding compost.
- Sow seeds ¼ inch deep, 2-3 seeds per spot.
- Space spots 18 inches apart.
- Water gently and keep soil moist.
- Thin to one seedling per spot after true leaves appear.
Direct-seeded cabbage often grows slower than transplanted cabbage. But it develops a stronger root system. For fall crops, this means better drought tolerance and storage life.
Best Cabbage Varieties For Georgia
Not all cabbage varieties handle Georgia’s heat. Choose varieties bred for southern conditions. Here are top picks:
Spring Varieties
- ‘Early Jersey Wakefield’: Heirloom, cone-shaped heads, matures in 63 days. Very heat-tolerant.
- ‘Stonehead’: Hybrid, round heads, matures in 65 days. Resists splitting.
- ‘Golden Acre’: Compact, early, matures in 62 days. Good for small gardens.
- ‘Red Acre’: Red cabbage, matures in 76 days. Holds color well in heat.
Fall Varieties
- ‘Savoy King’: Crinkled leaves, matures in 85 days. Very cold-tolerant.
- ‘Brunswick’: Heirloom, large heads, matures in 90 days. Stores well.
- ‘January King’: Ornamental and edible, matures in 100 days. Survives light freezes.
- ‘Danish Ballhead’: Storage cabbage, matures in 100 days. Keeps for months.
Try a mix of early and late varieties. This extends your harvest window. Plant some ‘Early Jersey Wakefield’ for spring and some ‘Brunswick’ for fall storage.
Care After Planting
Cabbage needs consistent care to form good heads. Neglect leads to small, loose heads or bolting. Here’s what to do after planting.
Watering
Cabbage needs 1-2 inches of water per week. More during hot, dry spells. Water at the base to avoid wetting the leaves—wet leaves invite fungal diseases. Use drip irrigation or a soaker hose if possible.
Inconsistent watering causes heads to crack. If you water heavily after a dry spell, the head swells too fast and splits. Keep soil evenly moist.
Fertilizing
Cabbage is a heavy feeder. Apply a balanced fertilizer (10-10-10) at planting time. Side-dress with nitrogen (like blood meal or fish emulsion) three weeks after transplanting. Repeat every 3-4 weeks until heads form.
Too much nitrogen late in the season makes heads loose and prone to rot. Stop fertilizing when heads start to firm up.
Mulching
Mulch around plants with straw, grass clippings, or shredded leaves. Mulch keeps soil cool, retains moisture, and suppresses weeds. In Georgia’s heat, a 2-3 inch layer of mulch is essential for spring cabbage.
For fall cabbage, mulch also insulates roots from early freezes. Pull mulch away from the stems to prevent rot.
Common Pests And Diseases
Georgia’s warm, humid climate is perfect for cabbage pests. You’ll need to stay vigilant. Here are the main problems and how to handle them.
Cabbage Worms
These are the larvae of white butterflies. They chew holes in leaves and can ruin a crop. Handpick them off leaves every few days. Use Bacillus thuringiensis (Bt) spray for heavy infestations. Row covers prevent butterflies from laying eggs.
Flea Beetles
Tiny black beetles that jump when disturbed. They eat small holes in leaves, giving them a “shotgun” appearance. Young plants are most vulnerable. Use diatomaceous earth or neem oil. Row covers also work.
Clubroot
A soil-borne disease that causes roots to swell and deform. Plants wilt and fail to form heads. Prevent by maintaining soil pH above 6.8. Rotate crops—don’t plant cabbage in the same spot for 3-4 years.
Black Rot
A bacterial disease that causes yellow V-shaped lesions on leaf edges. It spreads in wet weather. Remove infected plants immediately. Use disease-resistant varieties like ‘Blue Vantage’.
Harvesting Cabbage
Harvest when heads are firm and solid. Squeeze them gently—they should feel dense, not spongy. If the head feels loose, wait a few more days. But don’t wait too long; overmature heads split.
How To Harvest
- Cut the stem at the base with a sharp knife.
- Leave the outer leaves on the plant.
- Remove any damaged outer leaves from the head.
- Rinse off soil and dry thoroughly before storage.
For spring cabbage, harvest before temperatures consistently exceed 85°F. For fall cabbage, you can leave heads in the ground through light frosts. Frost actually improves flavor by converting starches to sugars.
Storage Tips
- Store in the refrigerator crisper drawer for up to 2 weeks.
- Wrap in a damp paper towel and place in a plastic bag.
- For long-term storage, keep in a root cellar at 32-40°F with high humidity.
- Fall cabbage stores longer than spring cabbage—some varieties keep for 3-4 months.
Don’t wash cabbage before storing. Moisture promotes rot. Wash just before use.
Frequently Asked Questions
Can I Plant Cabbage In Georgia In Summer?
Summer planting is not recommended. Cabbage stops growing when temperatures exceed 80°F. It bolts and becomes bitter. Stick to spring and fall planting.
What Is The Best Month To Plant Cabbage In Georgia?
For spring, February to March depending on your zone. For fall, July to August. Check your local frost dates for exact timing.
How Late Can I Plant Cabbage In Georgia?
For fall, you can plant as late as early September in South Georgia. In North Georgia, August 1 is the latest. Later planting risks immature heads before frost.
Does Cabbage Need Full Sun In Georgia?
Yes, cabbage needs 6-8 hours of direct sun daily. In South Georgia’s intense heat, some afternoon shade can help prevent bolting. But full sun is best for head formation.
Can I Grow Cabbage In Containers In Georgia?
Yes, use a container at least 12 inches deep and wide. Choose compact varieties like ‘Golden Acre’. Place in full sun and water daily in hot weather. Container cabbage needs more frequent fertilizing.
Final Tips For Success
Planting cabbage in Georgia is all about timing. Miss the window by two weeks, and you get tiny heads or no heads at all. Use a garden journal to track your planting dates and results. Adjust next year based on what worked.
Start small if you’re new. Plant 6-12 plants your first season. Cabbage takes up space but gives a big reward. One head feeds a family for a meal or two.
Watch the weather forecast. A sudden heat wave in April can ruin spring cabbage. Be ready to harvest early if needed. Imperfect heads still taste good in coleslaw or stir-fry.
Rotate your cabbage patch each year. Don’t plant cabbage, broccoli, or kale in the same spot for three years. This prevents soil-borne diseases from building up.
Finally, enjoy the process. Homegrown cabbage tastes nothing like store-bought. It’s crisp, sweet, and full of flavor. With the right timing, you’ll have a bountiful harvest from your Georgia garden.
