These days cauliflowers can be planted in almost any area of Australia. Check for local varieties.
- In cool and temperate regions of Australia, cauliflowers grow from April to August.
- In warm sub-tropical and tropical regions of Australia, cauliflowers grow from March to July.
- Pick a position in the garden that receives at least 6 hours of sun per day.
- Ensure plants are placed in a position away from high winds, as they can be easily damaged.
- Cauliflowers are frost tolerant, however in high frost area, plant in raised garden beds, away from low lying areas.

Follow our steps for easy soil preparation.
- Cauliflowers can be grown in all types of soil, however, they must be free draining so consider raised beds or rows.
- Add well-rotted manure and compost to the soil and dig it in to a depth of around 30cm. For a no-dig option, consider Seasol Liquid Compost.
- The pH of the soil should be 6.5 to 7.0. If it’s too low, add some lime to the soil at about a handful per square metre.
- Add Seasol Plant + Soil Booster (100 grams per square metre) and a fertiliser rich in potassium such as PowerFeed Controlled Release for Tomatoes & Vegetables to enrich the soil.
- Water in well and if possible, let the soil rest for a week or two.
