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?
Cauliflower does not usually develop side shoots, therefore most people will dig up the whole plant after harvesting the heads.
Put the dug up plants in your compost pile, but if there is any sign of disease on the plants dispose of them via other means ie Not via your compost pile.
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.
Unlike some of the responses, I have experienced secondary growth after harvesting the main Cauliflower head. So, I would suggest keeping the plant and giving it a change, assuming you don't have any other use of that space i.e. you are not ready to plant something else.
I picked my cauliflower and cabbage several weeks ago but left two of the plants in to see what would happen. They both have a lot of new growth on them, so I'm leaving them. One has at least six new shoots.
I live in phoenix it's now late March I harvested 6 nice califlower heads abut two weeks ago when I was removing the leaves for my compost pile I noticed new growth sprouting from the base of the main stocks i'll just leave them see what results I get? F Y I
