Quick answer
Grow cabbage in full sun, firm fertile soil and steady moisture. Select the cultivar by harvest season, because spring, summer, autumn and winter cabbages follow different calendars. Transplant sturdy young plants 30–60cm apart, cover them against birds and caterpillars, and cut each head when it feels firm.
Cabbage can supply a harvest in almost any month when several types are planned, but one plant does not crop continuously. Most form a single main head. Succession therefore comes from a sequence of varieties and sowings, not from leaving a mature head indefinitely.
Choose the right cabbage
Spring cabbage is commonly sown in late summer for small spring greens or pointed heads. Summer and autumn cultivars are usually faster and include round, pointed, red and Savoy types. Hardy winter cultivars stand cold conditions and may have blistered leaves. Storage cabbages form dense heads intended for harvest before severe weather.
Check maturity, final size, bolt resistance and field-holding ability. A compact cultivar can suit raised beds and containers; a large storage cabbage needs much more space. Red cabbage develops the strongest colour in good light, while Savoy leaves tolerate cold well.
Site, soil and rotation
Choose a sunny, open site protected from severe wind. Cabbages prefer moisture-retentive, well-drained soil around pH 6.0–7.0. Incorporate mature compost before planting, rake level and firm the bed. Very loose ground lets large plants rock, breaking fine roots.
Rotate with non-brassica crops. Cabbage shares clubroot and many pests with broccoli, cauliflower, kale, turnip and Brussels sprouts. The University of Minnesota Extension cabbage guide recommends a four-year interval from related crops where feasible.
Where clubroot is present, prioritise drainage, hygiene, resistant cultivars and locally appropriate pH correction. Raising pH without a soil test can create other nutrient problems.
Sowing and transplanting
Sow thinly in modules or a seedbed at the time specified for the cultivar group. Seedlings do not need high heat; bright light and moderate temperatures produce sturdier plants. Thin early and protect against slugs, flea beetles and birds.
Harden module-grown plants gradually. Transplant when young and actively growing, before roots circle densely. Place the root ball slightly deeper than it stood in the module, firm the soil and water in. A collar around the stem may help deter cabbage root fly where that pest is common.
Inspect the central growing point. A seedling whose centre has been eaten or damaged may never make a normal head, even if outer leaves continue growing.
Spacing and containers
Spacing controls head size. Use roughly 30–40cm for compact or spring types and 45–60cm for large heads, following the packet. Close spacing can create many smaller cabbages; wider spacing supports larger individual heads.
One compact cabbage can grow in a container of about 25 litres and 30cm diameter. The RHS cabbage guide also describes using larger containers for several plants. Use fresh peat-free compost, maintain drainage and allow for the weight of the mature head.
Watering, feeding and weed control
Water the full root zone during dry periods, particularly while heads are forming. Irregular moisture can check growth and later contribute to splitting when heavy rain arrives. Mulch after establishment to buffer moisture and suppress weeds.
Feed according to soil fertility. Cabbage needs nitrogen for its leaf mass, but excessive late nitrogen can reduce head quality. Shallow hoeing controls small weeds without cutting surface roots. Earth soil around a loose stem to improve stability.
Crop protection
Use fine insect mesh against egg-laying butterflies and root fly; use taut, wildlife-safe netting against pigeons. Seal edges and check for insects trapped beneath the cover. As leaves grow, enlarge or raise the structure so mesh does not abrade the plant.
Rotate, remove badly diseased debris and avoid walking soil from an infected bed into clean areas. Water soil rather than foliage where practical and give heads airflow.
Diagnosing common problems
| Symptom | Likely causes to investigate | First checks |
|---|---|---|
| No central head | Growing point damage, wrong season or severe stress | Plant centre, cultivar and history |
| Head splits | Rain or heavy watering after dry soil, over-maturity | Moisture pattern and firmness |
| Large holes or skeletonised leaves | Caterpillars, slugs or pigeons | Leaf undersides, droppings and net gaps |
| Plant wilts and roots are distorted | Clubroot | Root swellings and crop history |
| Plant collapses at soil level | Cabbage root fly or stem damage | Roots, larvae and collar |
| Loose head | Crowding, excess nitrogen, shade or immaturity | Spacing, feed, light and maturity date |
Harvest and storage
Press the head gently. Harvest when it is firm and has reached a useful size, cutting above the lowest sound leaves. Small secondary shoots sometimes develop from the remaining stump, but do not count on them as a second full head.
If a mature cabbage is likely to split before you can use it, harvest promptly. Some growers twist the head slightly to reduce water uptake, but cutting and cooling it is more predictable.
Use tender spring greens quickly. Dense storage types can last longer under cold, humid, well-ventilated conditions, although a domestic refrigerator does not reproduce a root cellar. Ferment only with a tested recipe and appropriate salt concentration.
