- Sowing
- Spring, timed for early, autumn or storage variety
- Harvesting
- Summer to autumn; depends on cultivar
- Location
- Sun, fertile soil and even moisture
- Space
- According to variety: approximately 30–60 cm as a practical guide
This growing advice helps you choose. Your variety, growth stage, weather and conditions in your space determine the actual timing.
Sowing under cover and raising seedlings
Start under cover in cool conditions in modules or a seedbed · White cabbage
March–May, only for a suitable harvest typeSow somewhere cool and bright and avoid long, weak growth.
- Germination and temperature
- Germinate under cover, then grow on in cool, bright, well-ventilated conditions; avoid a hot growing space.
- After emergence
- Give seedlings light immediately after emergence. A dark loft needs suitable grow lights; warmth alone is insufficient. Ventilate and keep the compost moist without saturating it.
- Pricking out and potting on
- Sow in modules or prick out manageable young plants. Let the root ball firm up without a check in growth.
- Hardening off and planting out
- Gradually acclimatise indoor-raised plants to sun, wind and outdoor temperatures; shelter them again on cold nights. Plant out sturdy young brassicas and protect against cabbage root fly and caterpillars where needed.
Early, summer, autumn and winter cultivars have their own windows. The spring period shown is a basic route; use cultivar guidance for overwintering and winter cauliflower.

How to grow white cabbage
The options below belong to the plant. From these, choose the method that suits your variety's growth habit.
This image was created with AI from described plant characteristics and growing advice. It shows a possible situation and is not a photograph of a verified cultivar.
One head per plant in a spacious bed
In open ground, white cabbage has room to form a firm head. Do not plant extra closely to promise more yield: outer leaves need light to feed the heart.
- Start in modules or begin with healthy young plants.
- Plant in prepared soil at the cultivar’s spacing.
- Place insect mesh over hoops and seal the edges well.
For anyone able to reserve a cabbage bed for much of the season.

A compact cultivar in a deep pot
A demonstrably compact cabbage variety can grow in a large, deep pot. Soil and position are easier to choose, but water and feeding need more attention. A small balcony pot gives insufficient roots for a large cabbage.
- Choose a cultivar with confirmed compact growth.
- Use a deep pot with drainage holes and suitable compost.
- Check moisture regularly and allow light and air to the leaves.

Netting works when the edges are closed too
Put the netting over sturdy hoops and secure it to the ground all the way round. Leave room for growth and check underneath without leaving the sides open for long.
View your supplies →Choose by flavour, shape and use
Brunswick: Brunswick is a late white cabbage with broad, flat, large heads on a short stem. The outside is described as green. Slice for sauerkraut or use parts cooked. A large head needs a plan for several portions.
The source gives no separate Brunswick aroma. Sauerkraut use and large head shape are concrete selection arguments.
A cabbage that suits your cooking
White cabbage suits a garden also growing for later use. A storage variety is a deliberate choice; an early variety gives fresh heads sooner. A few well-cared-for plants make development visible without a large field.
Sow for the intended harvest season
The same cabbage species can include early and late cultivars. Follow your cultivar's recommended sowing window and work in small batches. A late sowing of a long-season winter cultivar will not automatically catch up.
Sturdy plants in individual modules
Sow in clean seed compost and place emerged seedlings in good light. Keep the compost moist. An individual module gives each plant its own rootball. Move the plants before growth stalls for long in a cell that is too small.
Bring the soil into contact with the rootball
Acclimatise plants raised under cover to outdoor conditions. Plant in a sunny bed with good drainage and firm the soil around the rootball. Water to bring roots and soil into contact. Leave enough space for the mature leaves.
Support growth without waterlogging
Cabbages need fertile soil that retains moisture. Mature compost helps on poor or badly structured soil. Base additional feeding on the soil and product advice. Do not work wet clay into a compact, smooth planting hole where rainwater collects.
Even growth through to heart formation
Check the root zone more often during heart formation. Prolonged drought restricts development, while a sudden change to plentiful water may split vulnerable hearts. Water directly where needed during dry weather and retain an airy soil around the plant.
Avoid trapping the first caterpillars inside
Put insect mesh in place early and seal the edges, but also inspect beneath it. Mesh does not exclude a caterpillar already on a plant. Remove affected leaves and identify the pest before choosing a measure.
Consider all brassicas in your plan
Broccoli, cauliflower, Brussels sprouts and turnips also belong to the brassicas. Do not grow them in the same position every year. With clubroot, ordinary rotation is insufficient: have the cause assessed and use healthy starting material and a suitable growing position.
Feel the heart and look at the leaves
A closed, firm heart is a better signal than a fixed calendar day. Cut with a clean knife. Check splits and damage and use vulnerable heads first before setting intact storage heads aside.
Adapt storage to the cultivar
Store only intact heads of a suitable variety cool and inspect regularly. For sauerkraut or other fermentation, use a checked recipe and correct method. Leaving cabbage at room temperature is not a storage method.
