North Carolina cabbage growers set out transplants in March for spring crops or August for autumn. Knowing exactly when to plant cabbage in nc depends on your region and the weather, but these two windows give you a solid starting point. Cabbage loves cool weather, so timing your planting right means you avoid heat stress and get firm, sweet heads.
This guide walks you through the best planting dates for every part of North Carolina, from the mountains to the coast. You will learn how to read your local frost dates, prepare your soil, and care for your cabbage from transplant to harvest.
When To Plant Cabbage In Nc
North Carolina spans three USDA hardiness zones: 6b in the mountains, 7a and 7b in the Piedmont, and 8a along the coast. This means planting dates shift by two to four weeks depending on where you live. The general rule is to set out transplants 3–4 weeks before the last spring frost for a spring crop, or 6–8 weeks before the first fall frost for an autumn harvest.
Spring planting happens in March for most of the state, but mountain growers wait until April. Fall planting starts in late July for the mountains and runs through August for warmer areas. Let us break it down by region.
Spring Planting Dates By Region
For spring cabbage, you want the plants to mature before the heat of June. Cabbage stops forming heads when temperatures stay above 80°F. Here are the target transplant dates:
- Coastal Plain (Zone 8a): February 15 to March 15
- Piedmont (Zone 7a/7b): March 1 to March 31
- Mountains (Zone 6b): April 1 to April 30
If you start seeds indoors, count back 4–6 weeks from these dates. For example, a Piedmont gardener transplants around March 15, so start seeds indoors between February 1 and February 15.
Fall Planting Dates By Region
Fall cabbage actually tastes sweeter because cool weather concentrates the sugars. You want heads to form after the heat breaks but before a hard freeze. Target these transplant windows:
- Mountains: July 15 to August 1
- Piedmont: August 1 to August 20
- Coastal Plain: August 15 to September 10
Count back 6–8 weeks from your first expected fall frost date. For the Piedmont, first frost is usually mid-October, so transplant in mid-August.
Understanding North Carolina Frost Dates
Frost dates are your best friend when deciding when to plant cabbage in nc. Cabbage seedlings can survive light frosts, but hard freezes below 28°F can damage them. Here are the average last spring frost dates:
- Coastal Plain: March 15–March 25
- Piedmont: April 1–April 10
- Mountains: April 20–May 10
First fall frost dates average:
- Mountains: October 1–October 15
- Piedmont: October 15–November 1
- Coastal Plain: November 1–November 15
Check your specific zip code using the NC State Extension frost date tool. These dates are averages, so watch the 10-day forecast before planting.
How Cold Can Cabbage Tolerate
Cabbage is tough. Mature plants can handle temps down to 20°F for short periods. Young transplants are more sensitive, so harden them off for a week before setting them out. If a late freeze threatens, cover your plants with row cover or old sheets overnight.
For fall crops, cabbage actually improves with a light frost. The cold triggers the plant to convert starches to sugars, making the heads sweeter. But if temps drop below 25°F for more than a few hours, the outer leaves may freeze and rot.
Choosing The Right Cabbage Variety For NC
Not all cabbage varieties perform well in North Carolina’s humid summers and variable winters. Pick varieties that mature quickly for spring and resist bolting (going to seed) in heat. For fall, choose storage types that hold well in the field.
Best Spring Cabbage Varieties
- Early Jersey Wakefield: Heirloom, cone-shaped heads, matures in 60–65 days
- Golden Acre: Round, compact heads, 65 days, good for small spaces
- Stonehead: Hybrid, very uniform, 70 days, resists splitting
Best Fall Cabbage Varieties
- Brunswick: Heirloom, flat heads, 85 days, excellent storage
- Red Acre: Red cabbage, 75 days, holds color well
- Savoy King: Crinkled leaves, 80 days, cold tolerant
For the mountains, choose short-season varieties under 70 days for spring. For the coast, heat-tolerant types like Stonehead work best in the fall.
Preparing Your Soil For Cabbage
Cabbage is a heavy feeder. It needs rich, well-drained soil with a pH between 6.0 and 6.8. Test your soil at least two weeks before planting. You can get a kit from your county extension office for about $10.
If your pH is too low, add lime. For sandy coastal soils, add compost to hold moisture. For clay Piedmont soils, work in organic matter to improve drainage. Here is a step-by-step prep plan:
- Clear the area of weeds and rocks
- Spread 2–3 inches of compost or aged manure
- Apply a balanced fertilizer like 10-10-10 at 1 pound per 100 square feet
- Turn the soil to 8–10 inches deep
- Rake smooth and water deeply a day before planting
Do not plant cabbage where you grew broccoli, kale, or other brassicas in the past three years. This reduces the risk of clubroot and other soilborne diseases.
How To Plant Cabbage Transplants
Transplants give you a head start over direct seeding. Set them out on a cloudy day or in the late afternoon to reduce transplant shock. Space them 12–18 inches apart in rows 24–36 inches apart.
Follow these steps for success:
- Dig a hole deep enough to bury the stem up to the first set of true leaves
- Add a handful of compost to the hole
- Place the transplant and firm the soil around it
- Water thoroughly with a starter solution (diluted fish emulsion works)
- Mulch with straw or shredded leaves to keep soil cool and moist
If you are direct seeding (not recommended for spring because of heat), plant seeds 1/4 inch deep and thin to 12 inches apart after they sprout.
Spacing Tips For Bigger Heads
Closer spacing gives you smaller heads, wider spacing gives larger ones. For standard 3–5 pound heads, use 18 inches between plants. For giant heads over 10 pounds, space them 24 inches apart. For mini cabbages, 8–10 inches works fine.
Caring For Your Cabbage Plants
Cabbage needs consistent moisture and regular feeding. Inconsistent watering causes heads to crack. Aim for 1–1.5 inches of water per week, either from rain or irrigation.
Fertilize three weeks after transplanting with a side dressing of nitrogen. Use blood meal or a 21-0-0 fertilizer at 1 tablespoon per plant. Repeat every three weeks until heads start to firm up.
Pest And Disease Management
In North Carolina, cabbage faces several common pests. Cabbage worms, aphids, and flea beetles are the biggest problems. Use row covers from day one to block insects. If you see damage, spray with Bt (Bacillus thuringiensis) for worms or insecticidal soap for aphids.
Diseases like black rot and clubroot thrive in wet, warm conditions. Rotate crops, avoid overhead watering, and remove infected plants immediately. Resistant varieties help, too.
Common Cabbage Pests In NC
- Imported cabbageworm: Green caterpillars that chew holes in leaves
- Cabbage looper: Looping caterpillars that eat leaf edges
- Diamondback moth: Small gray moths that lay eggs on undersides
- Flea beetles: Tiny jumping beetles that make shot holes in leaves
- Aphids: Clusters of small insects on stems and leaf undersides
Harvesting Your Cabbage
Cabbage is ready when the head feels firm and solid when squeezed. A mature head should be about the size of a volleyball or smaller, depending on variety. Cut the head at the base with a sharp knife, leaving a few outer leaves to protect it.
For spring cabbage, harvest before temperatures consistently hit 80°F. Heads left too long in heat will split or bolt. For fall cabbage, you can leave heads in the garden through light frosts. Cover them with straw if a hard freeze is coming.
Storage tip: Keep cabbage in the refrigerator crisper drawer for up to two weeks. For longer storage, wrap heads in newspaper and store in a cool, dark place at 32–40°F. Some varieties keep for three months.
Common Mistakes When Planting Cabbage In NC
Even experienced gardeners slip up. Here are the top errors to avoid:
- Planting too late in spring: Heads form in heat and taste bitter
- Planting too early in fall: Young plants suffer from heat stress
- Overcrowding: Small heads and poor air circulation lead to disease
- Skipping soil test: Nutrient deficiencies cause poor growth
- Ignoring pests: Cabbage worms can destroy a crop in days
- Watering inconsistently: Leads to cracked heads
One more thing: do not plant cabbage in the same spot two years in a row. Rotate with beans, corn, or tomatoes to break pest cycles.
Frequently Asked Questions
Can I Plant Cabbage In North Carolina In The Summer?
No, summer heat causes cabbage to bolt and taste bitter. Stick to spring and fall planting windows. For a continuous harvest, plant a spring crop and a fall crop.
How Long Does Cabbage Take To Grow In NC?
Most varieties mature in 60–85 days from transplant. Spring crops planted in March are ready by May or June. Fall crops planted in August are ready by October or November.
What Is The Best Month To Plant Cabbage In The Piedmont?
For spring, plant transplants in March. For fall, plant in mid-August. The Piedmont’s mild climate allows two crops per year.
Should I Start Cabbage Seeds Indoors Or Buy Transplants?
Buying transplants is easier for beginners. If you start seeds indoors, do so 4–6 weeks before your target transplant date. Use grow lights or a sunny windowsill.
Can Cabbage Survive A North Carolina Winter?
Some varieties can overwinter in coastal areas with protection. In the mountains, winter kills cabbage. For a winter harvest, plant in late summer and cover with row cover or a cold frame.
Now you know exactly when to plant cabbage in nc. Spring crops go in March for most of the state, fall crops in August. Check your local frost dates, choose the right variety, and give your plants consistent care. With these tips, you will be pulling firm, sweet heads from your garden in no time.
If you have clay soil, add extra compost. If you have sandy soil, water more often. And always keep an eye on those cabbage worms. Happy growing, North Carolina.
