How to Grow Cabbage in Warm Temperate Australia
- 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.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- pH Range
- 6.0-7.5
- 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 splitting.
- Good companions
- Nasturtium (trap crop), Dwarf Beans, Onion, Cucumber, Dill
- Keep away from
- Garden Cress, Grape, Lemongrass, Peach, Pear, Strawberry, Tomato
- Grow before it
- Legumes (Beans - Dwarf, Peas, Broad Beans)
- Grow after it
- Fruiting crops (Tomato, Capsicum, Zucchini)
Give the bed 3 turns before brassicas go back in. The cabbage family is hungry for nitrogen and shares club root and other soil diseases.

- Dehydrating. Shred cabbage thinly. Blanch 1-2 minutes, cool, drain well. Spread on dehydrator trays. Dry at 55C for 8-12 hours until brittle. Store in airtight containers. Rehydrate in warm water for 20 minutes before use. Keeps: 6-12 months.
- Kimchi. Quarter cabbage, salt heavily, and soak 2-12 hours. Rinse well. Make paste of gochugaru (Korean chilli flakes), fish sauce, garlic, ginger, sugar.
