How often to water Cabbage
- Spring–Summer (Mar–Sep)
- Every 2 days
- Water thoroughly once the topsoil dries, as a guide, and do not let it dry out just after planting or while the head starts to form.
- Autumn (Oct–Nov)
- Every 3 days
- Water in the morning about when the topsoil dries, as a guide, easing off a little once the head firms up.
- Winter (Dec–Feb)
- Every 5 days
- Growth slows, so as a guide water on a mild morning about two to three days after the soil dries.
Light and placement for Cabbage
A spot outdoors with sun through the day and good airflow is about right, since low light keeps the head from forming; caterpillars are generally a problem, so cover it with an insect net at planting.
Overwintering Cabbage
Overwintering guide: −5°C (23°F) or above
Cold-hardy and generally left outdoors through winter; for a spring harvest from autumn planting, aim to enter winter as a smallish plant of about ten leaves, as larger ones tend to bolt in spring.
Fertilizing and repotting Cabbage
Fertilizer
Plant into soil with a base fertilizer, then as a guide side-dress with granular fertilizer and hill up twice, two to three weeks later and when the head begins to form; bigger outer leaves mean a bigger head.
When to repot
Spring–Summer (Mar–Sep), Autumn (Oct–Nov)
Common problems with Cabbage
- Cabbage worms and cutworms strip the leaves and no head forms.
- In a small, shallow pot the roots cannot spread and the head stays tiny.
- Harvested too late, the head splits.
Tips for growing Cabbage
- In a planter, one or two plants in a large container about 30 cm deep is a good guide.
- Check the undersides of the leaves often and remove eggs and larvae early.
- The head is ready to cut when it feels firm and tight under your hand.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
