Will cauliflower do anything after you pick the main flower like broccoli or should I just pull the whole plant out when I'm harvesting?
Maybe we should rethink the way we garden! I, too cut the main head off that was huge on my fall cauliflower. But it had been planted next to a new fruit tree and I did not want to disturb the roots so I left it there thinking that it would decompose on its own. In the spring it produced 4 side shoots - each producing a very full head. I cut those off and guess what - it produced again in the fall. Unfortunately, my chickens got out and ate the plant for dinner one cold morning. I have an eggplant that is 3 years old and still producing along with various peppers and a cabbage that has 3 medium size heads on it at the moment. All of these plants are heirlooms and maybe we should all take a look to see if traditional pulling and replanting is really the optimal way to go. Good luck!
My dog figured out that cauliflower is delicious. Two plants survived with just a nub of the flower intact. They have regrown and I now have two more heads! They are not as tightly packed as the first ones were. I have also cut off some of the leaves and eaten them as well. I am going to cut off the majority of the head and see if it will do it again.
I have cut my Lime colored heads mid summer. It's now mid September and both regrew bigger than first head. No lie. Didn't pull in first place because too big, and then I just wanted to see what would happen. Nice surprise. Totally rethinking cauliflower in next year's garden. I am in zone 5-6, mountainish area in Oregon. Dry summer, crazy wet fall.
