I bought some Cauliflower from a nursery and heads were pretty badly damaged. So I harvested the 3 inch heads. I read that broccoli will start new florets if you harvest- will my cauliflower? Did I ruin my crop for the season?
Yes most broccoli will produce side shoots after the head is harvested. I have never had cauliflower that has done that, once you harvest the head it is done. That is not to say that there might be a variety that produces side shoots, but I have never had any.
