Cauliflower is a popular and rewarding crop for home gardeners. Here are some common questions about growing cauliflower.

When is the best time to plant cauliflower in Australia?

Cauliflower grows best in cooler months, making autumn and early spring ideal times to plant it in Australia. Planting during these seasons helps the plant establish well before extreme temperatures. Discover what other veggies you should plant in autumn.

How long does it take for cauliflower to grow?

Cauliflower typically matures in 10–14 weeks. Harvest cauliflower when the heads are firm and compact, usually around 10 cm in diameter, depending on the variety.

Does cauliflower need full sun?

Yes, cauliflower grows best in full sun but can tolerate some part shade in hotter climates. Adequate sunlight ensures strong head formation and healthy growth.

How do I prevent pests like cabbage moths on my cauliflower plants?

To protect cauliflower plants from common pests like cabbage moth, use lightweight garden covers or practice companion planting with strong-scented herbs like sage and dill. These methods help deter pests while promoting healthy plant growth.

How do I plant cauliflower seedlings for the best results?

How do I prevent my cauliflower heads from turning yellow?

To keep cauliflower heads white and prevent yellowing, gather a few leaves over the head as it forms and secure them loosely. This protects plants from direct sunlight, keeping the heads compact and vibrant.
