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.
