It's tough to raise quality cauliflower in warm areas in summer....period.

Some varieties are called self-blanching which means that the inner leaves cover the head more than others do. Still, you must be sure that the new head is covered with leaves totally. Either by tieing the leaves tightly over the head at a very small size or having a totally self-wrapping variety. Heads exposed to light become yellow and off flavor. The whole process of heading to harvest is only 10 days or less.
I guess I would not agree about the insect problem.

My cauliflower plants have been completely chewed down by cabbage worms and trampled on by squirrels so I am far from an expert in these matters; however, if you plant either a yellow cauliflower like cheddar or a purple variety like graffiti, the leaves don't need to be tied back over the nascent heads. Direct sunlight supposedly intensifies the color likely because the pigments are protective radical quenchers.

Concur, If you want to grow white cauliflower below the Mason Dixon line, you will need to tie it up. Direct sunlight will not only cause it to color, It will make it strong flavored. The colored types,don't need tieing up. The cabbage worms don't care whether you do or not. I just feed them a good diet of Bt, and have no problems with them.
