Growing Cabbage in Australia: The Complete Guide

Cabbage is a moderate brassica to grow, needing full sun with consistent, deep watering.

We get asked about cabbage often enough that it's worth setting out the full picture here, beyond what fits on our printable card.

Firm heads need space

Give cabbage full spacing from the start — crowded plants form loose, small heads and are far more prone to pest and disease pressure.

Planting Cabbage

Method — transplant seedlings; firm soil well around the base. Soil — rich, well-drained, high organic matter. Timing — plant in cooler months — spring or autumn depending on zone.

Ongoing Care

Worth paying attention to:

  • Water deeply and consistently — inconsistent watering splits heads.
  • Feed with nitrogen-rich compost early, then ease off as heads form.
  • Net against cabbage moth from planting.
  • Twist heads slightly at maturity to reduce splitting if leaving in place.

Common Problems

Keep these points in mind:

  • Cabbage moth/white butterfly — caterpillars shred leaves; net or hand-pick.
  • Clubroot — swollen, distorted roots; keep pH up, rotate for years.
  • Aphids — cluster under leaves; hose off or encourage ladybirds.
  • Head splitting — irregular watering, especially heavy rain after dry.

Harvest and Storage

Signs — head feels firm and solid when gently squeezed. Method — cut at the base with a sharp knife, leaving outer leaves and roots for a smaller second flush. Curing — none needed. Storage — fridge crisper 2–4 weeks; whole heads keep longest.
