(Best months for growing Cauliflower in New Zealand - cool/mountain regions)

S = Plant undercover in seed trays T = Plant out (transplant) seedlings

  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 50°F and 86°F. (Show °C/cm)
  • Space plants: 24 - 39 inches apart
  • Harvest in 15-22 weeks.
  • Compatible with (can grow beside): Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile)
  • Avoid growing close to: Climbing (pole) beans, tomato, peppers (chili, capsicum), eggplant (aubergine), strawberry, mustard
  • Mature cauliflower

Large leafed cabbage-like with a white 'curd' or flower forming in the centre. It can be hard to grow successfully. More frost sensitive than most brassicas, it's also not particularly heat tolerant. They tend to fail if stressed when transplanting.

Watch for cabbage white butterfly. Grow better in cooler temperatures. Not suitable for warm areas. Break a leaf over the head to prevent the curd becoming discoloured

Culinary hints - cooking and eating Cauliflower

Cauliflower can be eaten raw, steamed, stirfried, grilled, or roasted. Popular grated and steamed/stirfried as a low-carb rice substitute.
Cook briefly and add to curry mix.
Traditionally served with cheese sauce. Add tomato slices for colour.
Toss with oil and spices and roast/grill until browned and delicious!

I live in Nigeria. I love cauliflower so much and I am very interested in growing it in my house garden, is there any advice I can get to grow it?

It is probably too hot in Nigeria, needs cool climate in winter.

A lot of commercial vegies around here are fertilised with Nitrophoska with the trace elements in it $36 a 25kg bag.

I'm sub tropical and I don't even try to grow caulies. They need a cool cold climate. An agronomist told me the other week cauli, broccoli, cabbage, lettuce need it to be cool/cold to form a head. I have tried growing them but end up with huge leafy plants and no or little head, reason, over fertile soil. To really be on the ball on growing them you would have to have a soil test done, then a specific fertiliser would have to be applied. You may only have a small time window to plant them, say April to mid May. Talk to an agronomist in your area if you can.

There are cauliflower varieties adapted to hot climate. Even cabbage, broccoli etc. Check SAKATA seeds or Global seed company.
