I've tried growing caulis both in my old location (Brisbane Australia, subtropical frost free climate) and here in Toowoomba (tableland, moderate frosts), plus mini caulis here and they have turned out rather funky! The cauli in the middle seems to have developed perfectly while the outside ones have splayed out everywhere. This seems to be a recurring problem I have with growing caulis. Can anyone shed some light on the problem for me?
I'd love to agree, but the heads only formed the size of a thimble before splaying out like above. This seems to happen everytime I grow caulis, and I can't seem to fathom why. The plants are fell watered and fed, 6-8 hours of sun per day, just got no idea!
It may be heat, cauliflower is a cool weather crop. We can only grow them here in the latewinter early spring and in fall early winter. There are some cultivars designed for the tropics but I suspect they are grown at high elevations where the nights are cool.
Problem is that this is the middle of Winter here, and I'm on top of the range! (remember I'm in the southern hemisphere)
Been getting mild frosts here for a month now, major broccoli & cauliflower growing region here, no idea what I'm doing wrong!
Your best bet may be to do a walk about with local growers and see how they do it. Most of what I have learned over the years has been from watching successful growers.
