Cauliflower is a cool-season crop and a descendant of wild cabbage. It is more difficult to grow than its relatives because it does not tolerate the heat or cold as well.
If you plan to attempt growing cauliflower in the home garden, it requires consistently cool temperatures with temperatures in the 60s. Otherwise, it may prematurely “button”—form small, button-size heads—rather than forming a single, large, white head.
Given that cauliflower enjoys cool temperature, it’s a good autumn crop in many regions. Because of its temperature requirements, however, cauliflower is usually grown commercially and not the best crop for the beginner gardener. Are you up for the challenge?
