Cabbage plants form tighter heads when they mature during the cooler parts of the growing season. Knowing when is the best time to plant cabbage can make the difference between a bumper crop and a disappointing harvest. This guide walks you through the exact timing for spring, fall, and winter cabbage, plus tips for your specific climate.
You don’t need a green thumb to grow great cabbage. You just need the right timing. Let’s break it down step by step.
When Is The Best Time To Plant Cabbage
The short answer: plant cabbage so it matures in cool weather. For most gardeners, that means a spring crop or a fall crop. Cabbage hates heat. When temps rise above 80°F (27°C), heads stop forming and may split or bolt.
Here’s the simple rule of thumb: count backward from your first fall frost date or forward from your last spring frost date. Cabbage takes 70 to 120 days from seed to harvest, depending on the variety.
Spring Planting Window
For a spring harvest, you want cabbage to mature before summer heat hits. Start seeds indoors 6 to 8 weeks before your last expected frost. Transplant seedlings outdoors 2 to 4 weeks before that last frost date.
- Indoor seed starting: 6–8 weeks before last frost
- Hardening off: 1 week before transplanting
- Transplant outside: 2–4 weeks before last frost
- Harvest: 60–100 days later, usually late spring to early summer
If you live in a cold climate (zones 3–5), your last frost might be in May. So start seeds in March. For warmer zones (6–8), start in February or early March. In hot climates (zones 9–10), skip spring cabbage altogether—it gets too hot too fast.
Fall Planting Window
Fall cabbage often tastes sweeter because cool temps increase sugar content. The trick is to time it so heads form during autumn’s cool days, not summer’s heat.
Count backward from your first fall frost date. For most varieties, you need 80 to 110 days from seed to harvest. Plant seeds directly in the garden 10 to 12 weeks before the first frost. Or start indoors 12 to 14 weeks before.
- Find your first fall frost date (check local almanac or extension office)
- Subtract 80–110 days for your cabbage variety
- Plant seeds on that date
- Transplant seedlings 4–6 weeks later if starting indoors
For example, if your first frost is October 15, plant seeds around July 1–15. In warmer zones (7–8), you might plant in August for a November harvest. In zones 9–10, plant in September or October for a winter harvest.
Winter Cabbage In Mild Climates
If you live in zones 8–10, you can grow cabbage through winter. Plant in late summer or early fall. Heads will form during the cool winter months. Some varieties, like ‘January King’ or ‘Savoy’, handle light frosts well.
In these areas, the best time to plant is September through November. Harvest from December through March. Just protect plants from hard freezes with row covers or cloches.
Factors That Affect Planting Time
Your exact planting window depends on several things. Don’t rely on a generic calendar. Adjust for your specific situation.
Your USDA Hardiness Zone
This is the biggest factor. Zones 3–4 have short growing seasons. Zones 9–10 have long, hot summers. Here’s a quick zone guide:
- Zones 3–4: Spring only. Start indoors in March, transplant in May. Fall planting is risky due to early frost.
- Zones 5–6: Spring and fall. Spring: start seeds February–March. Fall: plant seeds July–August.
- Zones 7–8: Spring and fall. Spring: start seeds January–February. Fall: plant seeds August–September.
- Zones 9–10: Fall and winter. Plant seeds September–November. Skip spring.
Cabbage Variety Maturity Time
Early varieties mature in 60–70 days. Mid-season take 70–85 days. Late varieties need 85–120 days. Check the seed packet. If you plant a 100-day variety in late summer, it might not mature before frost.
For spring, choose early or mid-season varieties. For fall, mid-season or late varieties work well. In winter gardens, go with cold-hardy types like ‘Savoy’ or ‘Red Acre’.
Soil Temperature
Cabbage seeds germinate best when soil is between 45°F and 85°F. The sweet spot is 60–70°F. If soil is too cold (below 40°F), seeds rot. If too hot (above 85°F), germination drops.
Use a soil thermometer. For spring, wait until soil reaches at least 45°F. For fall, plant when soil is still warm but not scorching—usually late summer.
Day Length And Sunlight
Cabbage needs full sun—at least 6 hours daily. But it also prefers cool temperatures. In spring, longer days and rising temps can stress plants. In fall, shorter days and cooling temps are ideal.
Some varieties are day-neutral, meaning they form heads regardless of day length. Others are sensitive. Check your seed catalog. For fall planting, choose day-neutral or long-day varieties.
Step-By-Step Planting Guide
Follow these steps for perfect timing and healthy plants.
Step 1: Choose Your Season
Decide if you want spring, fall, or winter cabbage. Base it on your zone and personal preference. Spring cabbage is great for coleslaw and stir-fries. Fall cabbage stores well for winter use.
Step 2: Select The Right Variety
Match the variety to your season. For spring, try ‘Early Jersey Wakefield’ (65 days) or ‘Golden Acre’ (65 days). For fall, ‘Brunswick’ (85 days) or ‘Danish Ballhead’ (100 days). For winter, ‘Savoy King’ (80 days) or ‘January King’ (120 days).
Step 3: Calculate Your Planting Date
Use the frost date method. For spring: count back from last frost. For fall: count back from first frost. Write the date on your calendar. Set a reminder to start seeds or transplant.
Step 4: Start Seeds Indoors (Spring Only)
For spring, start seeds in seed trays with good drainage. Use seed-starting mix. Plant seeds ¼ inch deep. Keep soil moist and warm (65–70°F). Provide 12–16 hours of light once seedlings emerge.
Harden off seedlings 7–10 days before transplanting. Set them outside for a few hours daily, increasing time gradually. Protect from wind and direct sun at first.
Step 5: Prepare The Garden Bed
Cabbage loves rich, well-drained soil with a pH of 6.0–7.5. Add compost or aged manure a few weeks before planting. Work it into the top 6–8 inches. Space plants 12–24 inches apart, depending on variety. Rows should be 24–36 inches apart.
Step 6: Transplant Or Direct Sow
For spring, transplant hardened-off seedlings on a cloudy day or in late afternoon. Water well. For fall, you can direct sow seeds ½ inch deep, then thin to the right spacing. Keep soil consistently moist.
Step 7: Provide Care Through The Season
Water deeply once or twice a week, providing 1–1.5 inches per week. Mulch with straw or grass clippings to keep soil cool and moist. Fertilize with a balanced fertilizer (10-10-10) when plants are 6 inches tall, then again when heads start forming.
Watch for pests like cabbage worms, aphids, and slugs. Use row covers early in the season. Handpick caterpillars. Apply neem oil if needed.
Common Timing Mistakes And How To Avoid Them
Even experienced gardeners mess up timing. Here are the most common errors and fixes.
Planting Too Late For Spring
If you plant spring cabbage after your last frost date, heads may form in hot weather. They’ll be loose, bitter, or bolt to seed. Solution: start seeds indoors early. Don’t wait until soil warms up naturally.
Planting Too Early For Fall
Planting fall cabbage in midsummer means seedlings face intense heat. They may struggle, get stressed, or attract pests. Solution: wait until late summer or early fall, depending on your zone. Use shade cloth if temps are above 85°F.
Ignoring Microclimates
Your garden might be warmer or cooler than the general zone. South-facing slopes warm up faster. Low spots collect cold air. Solution: observe your garden. Note frost pockets and warm areas. Adjust planting dates by 1–2 weeks.
Not Accounting For Variety Differences
All cabbages are not the same. A 60-day variety planted in August might be ready in October. A 120-day variety planted in August might be killed by frost in November. Solution: always check the days to maturity on the seed packet.

How To Extend Your Cabbage Season
Want cabbage for months? Use these strategies.
Succession Planting
Plant a few cabbage seeds every 2–3 weeks during your planting window. This gives you a continuous harvest instead of one big batch. For spring, plant early, mid, and late varieties at the same time. For fall, stagger plantings by 2 weeks.
Using Row Covers
Floating row covers protect plants from frost and pests. They can extend your season by 2–4 weeks in spring and fall. Use lightweight fabric for frost protection. Remove covers when temperatures rise above 80°F.
Growing In Containers
If your garden has poor soil or limited space, grow cabbage in large containers (at least 5 gallons). You can move containers to sunnier or shadier spots as needed. This gives you more control over temperature.
Choosing Quick-Maturing Varieties
For a fast crop, choose varieties that mature in 60–70 days. ‘Early Jersey Wakefield’ and ‘Golden Acre’ are reliable. You can plant them later in spring or earlier in fall and still get a harvest.
Frequently Asked Questions
Can I Plant Cabbage In The Summer?
Summer planting is risky in most areas because heat stresses the plants. If you must, choose heat-tolerant varieties like ‘Savoy’ or ‘Red Acre’. Provide shade and consistent moisture. Expect smaller heads.
What Happens If I Plant Cabbage Too Late In Spring?
Heads may not form properly. They can become loose, split, or bolt to seed. The flavor turns bitter. It’s better to skip a late spring planting and wait for fall.
How Do I Know When To Harvest Cabbage?
Heads should be firm and solid when squeezed. They should reach the expected size for the variety. Harvest before they split. Cut the stem at the base with a sharp knife.
Can I Grow Cabbage In Hot Climates?
Yes, but only as a fall or winter crop. In zones 9–10, plant in September–November. Use shade cloth and mulch to keep soil cool. Choose heat-tolerant varieties like ‘Savoy’ or ‘January King’.
Do I Need To Fertilize Cabbage?
Yes. Cabbage is a heavy feeder. Apply a balanced fertilizer at planting time and again when heads start forming. Side-dress with compost or fish emulsion every 3–4 weeks.
Final Tips For Success
Timing is everything with cabbage. Get that right, and the rest is easy. Keep a garden journal. Note your planting dates, frost dates, and harvest results. Adjust next year based on what you learn.
Don’t be afraid to experiment. Try a spring crop and a fall crop. See which works better in your garden. Talk to local gardeners or your extension office for zone-specific advice.
Remember: cabbage is forgiving. Even if you’re off by a week or two, you’ll likely get something. The key is to avoid extreme heat. Cool weather is your friend.
Now you know when is the best time to plant cabbage. Get your seeds, check your calendar, and start growing. Your future coleslaw and stir-fries will thank you.
