How to Grow Cabbage in Cold / Highland Australia
When to Plant
October-January (spring-summer). Protect autumn transplants from early frosts. Harvest January-May.
- 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.

- Full sun (6-8 hours minimum). Part shade tolerated in subtropical/tropical zones.
- Spacing
