Cauliflower Growing Guide


  • Temperate areas: Sow late December to May.
  • Very cool, highland areas: Sow October to February.
  • Inland areas: Sow February to September.
  • Subtropical areas: Sow March to June.
  • Tropical areas: Sow April to July.

Climate Considerations:

  • Cauliflowers struggle in subtropical and tropical regions due to hot weather.
  • Hybrid varieties are preferable in hotter climates as they resist bolting (going to seed prematurely) and maintain quality.
  • Plant early in hotter areas to ensure maturity before spring warmth.


  • Sow seeds 10mm deep in trays or seedbeds. Germination typically takes 4-10 days.
  • Transplant seedlings by removing seed leaves and planting deeper, up to the first set of true leaves.
  • Space plants 40cm apart in rows 60-75cm apart.

Soil Requirements:

  • Cauliflowers thrive in fertile, well-drained soil with a pH of 6-7.5.
  • Amend soil with well-rotted compost or animal manure to ensure adequate nutrients.
  • Keep soil consistently moist, especially during the growing period.


  • Cauliflowers are heavy feeders, requiring ample nitrogen and potassium.
  • Apply organic fertilizers when plants are half-grown to support healthy growth.


  • Harvest cauliflowers while heads are still tight and white.
  • Avoid waiting too long, as over-mature heads can become discolored or develop loose curds.

By following these simple steps, you can cultivate delicious cauliflowers in your Australian garden. Remember to adjust planting times and varieties based on your specific climate zone for optimal results.
