How to Grow Cabbage in Warm Temperate Australia

When to Plant

Two windows: February-April (autumn) and July-September (late winter/spring). Main harvest May-November.

Soil
Rich, firm, well-drained soil with heavy compost and aged manure. Cabbage needs solid soil structure for head formation; loose sandy soils produce loose heads.

Sunlight
Full sun (6-8 hours minimum). Part shade tolerated in subtropical/tropical zones.
Spacing
50cm apart, 60cm between rows
Watering
Deep, consistent watering 2-3 times per week. Inconsistent watering causes split heads. Drip irrigation ideal. Avoid overhead watering to reduce disease. Reduce water as heads firm up to prevent split
