Planting and Growing Cabbage

Jun 17, 2021by David Schulze

There is something satisfying about cutting a firm head of cabbage that you grew from seed. Whether you enjoy fresh coleslaw, a skillet supper or sauerkraut, cabbage earns its place in a home vegetable garden.

Success starts with choosing a suitable season and variety, raising sturdy plants and keeping growth steady. This guide brings together direct sowing and transplanting advice with harvesting, storage and lessons from our gardening experience at David's Garden Seeds®.

Choose Cabbage for Your Garden and Kitchen

Green, red and crinkled savoy types offer different colors and textures. Compare mature head size, spacing, kitchen use and maturity. Early varieties fit shorter growing windows, while larger or storage-oriented varieties may need more time and room.

Check whether days to maturity begin at sowing or transplanting. A transplant-based estimate does not include the weeks raising seedlings. This guide covers heading cabbage; crops sold as Chinese cabbage may require different timing and care.

Plan Around Cool Weather

Cabbage is a cool-season crop. Aim for head development during mild weather rather than persistent summer heat. Spring and fall are common growing seasons; mild-winter regions may also support winter crops.

Texas dates vary by region. Check your county Extension calendar and work backward from the variety's maturity. For fall, allow enough time for growth before short days and cold slow development.

Established plants tolerate some frost, but tender indoor seedlings need acclimation and severe freezes can still damage crops. Hardening off does not make plants immune to extreme conditions.

Prepare a Sunny, Well-Drained Bed

Choose a sunny site with fertile soil and good drainage. Add finished compost as appropriate and use soil tests to guide fertilizer and pH changes. Remove weeds so seedlings do not face immediate competition and avoid low areas that remain soggy.

Before planting, review our seed germination guide and soil-testing guide.

Direct Sow When Conditions Are Suitable

Direct sowing works when outdoor temperatures and soil fit the crop. Trays offer another option where the planting window is short or outdoor conditions are difficult.

Follow packet depth: About 1/4 inch is common. Deeper is not automatically better.
Sow and thin: Two seeds at each intended spot can provide a backup; thin to one healthy plant after establishment.
Water gently: Keep the seed zone evenly moist without waterlogging or washing seed away.
Allow time: Emergence depends on temperature, moisture and seed condition. Use expected ranges rather than one fixed day.

One lesson I learned early was that planting deeper does not improve the odds. I once treated a green bean packet's one-inch depth as an invitation to try two inches. Measure instead of making the seed work harder.

Start Seeds in Clean Containers

Use trays or pots with drainage and a well-drained seed-starting mix. Sow at packet depth and keep moisture even. Provide strong light immediately after emergence to prevent weak, stretched plants.

Thin or separate seedlings to give roots and foliage room, potting up when necessary before crowding. Transplant when plants are sturdy with several true leaves and conditions suit the crop, not solely because a certain number of days has passed.

Harden Off and Transplant Carefully

Gradually expose indoor-grown plants to outdoor light, wind and temperature over several days. Begin sheltered and increase exposure while monitoring moisture. Do not move soft growth directly into intense sun, strong wind or a cold snap. Read our hardening-off guide.

Set transplants carefully, water the root zone and keep the central growing point above soil. Follow variety-specific depth and spacing directions.

Give Mature Plants Enough Room

Roughly 12–24 inches between plants is common, but compact and large-headed varieties differ. Some fit 12–18 inches while larger types need more. Follow the packet and leave row access for tending and harvest.

Thin direct-sown rows rather than keeping crowded seedlings. Crowding limits head size and airflow. Containers can work with a compact variety, a roomy pot and drainage, but require more frequent moisture checks.

Water and Feed for Steady Growth

Check soil and water thoroughly as needed, adjusting for rainfall, temperature and texture. Containers and raised beds may dry faster than in-ground soil.

Mulch established plants to conserve moisture and reduce weeds, keeping stems clear. Avoid severe drying followed by soaking, especially near maturity, because uneven moisture contributes to head splitting.

Feed according to soil tests and product labels. Seedlings need a gentler approach than established plants; height alone is not a reason to switch to full-strength fertilizer. Extra feed does not fix drainage, crowding or excessively hot weather.

Protect Plants from Insect Pests

Inspect leaf undersides and growing centers for cabbage worms, loopers, flea beetles, aphids, eggs and fresh damage. Early discovery gives more options.

Use barriers early: Secure fine insect netting or appropriate row covers before pests arrive, inspect beneath and monitor heat.
Remember the harvest goal: Cabbage grown for heads does not need insect pollination, so suitable netting can stay in place if growing conditions allow.
Handpick small infestations: Remove identified caterpillars where practical and keep monitoring.
Target the actual pest: Soap is not a universal solution. If needed, use a product labeled for cabbage and the identified problem, following application and harvest intervals.

Marigolds add variety but do not form a dependable cabbage-caterpillar barrier. Homemade or organic sprays are not automatically harmless, and routine insecticide or fungicide applications without a need are not a substitute for monitoring.

Reduce Disease Pressure

Use clean transplants, drainage and adequate spacing. Rotate cabbage and related brassicas where practical and remove badly diseased material appropriately.

Persistent wilting, discoloration or abnormal roots require investigation before adding fertilizer, water or a spray. Avoid transferring soil from problem beds to clean areas. Ask Extension for help with uncertain or recurring symptoms.

Harvest Firm Heads Before Splitting

Use maturity estimates as a guide, then feel the head. Harvest when firm for the type and at a useful size rather than waiting for every variety to become enormous.

Cut with a clean sharp knife, leaving sound wrapper leaves to protect the head. Timely harvest and steady watering are more useful than expecting mature heads to hold indefinitely.

If the plant remains healthy, leaving lower leaves and stem may produce small side heads, but this is a possible bonus, not a guaranteed second harvest.

Bolting means producing a flower stalk, not forming a head. Variety, age and temperature exposure can contribute. A bolting plant is unlikely to produce the quality head you expected.

Store and Use Your Harvest

Refrigerate heads promptly and protect from moisture loss. Keep sound wrapper leaves until preparation and discard decaying material. Storage depends on variety, head condition and temperature; not every cabbage is a long-storage type and a household shelf is not necessarily cool enough.

Wash before preparing. Shred for slaw, sauté with onions, add to soups or roast wedges. For sauerkraut or kimchi, follow a tested fermentation recipe, including salt, temperature and storage instructions. Fermentation is not simply leaving cabbage on a counter.

Nutrition in Harvested Cabbage

Cabbage supplies vitamin C, vitamin K and dietary fiber among other nutrients. Red cabbage also contains anthocyanin pigments. Amounts vary with variety, portion and preparation; raw and cooked servings are not identical.

This refers to harvested cabbage, not planting seed. Enjoy it in a varied diet rather than as a promise of disease prevention or weight loss. Dressings, oils and other ingredients change the finished dish's nutrition.

Saving Cabbage Seed Is a Separate Project

Cabbage is generally biennial and usually needs to survive beyond its first season and experience suitable cold before flowering. Growing heads for eating is different from keeping plants for seed.

Open-pollinated varieties can be candidates, but one cabbage variety alone does not prevent crossing with other flowering crops of the same species. Research overwintering, isolation, pollination and suitable population size before beginning.

Frequently Asked Questions

Why is my cabbage not forming a head?

It may need more time, or heat, crowding, poor light, water stress or growing-point damage may limit it. Review the variety and conditions before assuming more fertilizer is needed.

Can I grow cabbage in a container?

Yes. Choose suitable compact varieties and roomy containers with drainage and sufficient root space, monitoring moisture closely.

Can I keep netting on while heads develop?

Heading cabbage does not require insect pollination. Appropriate netting can remain where heat, airflow and growth conditions are managed.

Will the plant grow another head after cutting?

A healthy remaining stem may develop smaller side heads, but do not count on a full second crop.

Keep Learning from Your Garden

Record varieties, sowing and transplant dates, weather, pest pressure and harvest. Some seasons go better than others. Adjust from observation while keeping local timing and consistent care at the center of the plan.
