If you grow a raab (also known in Italian as
rapini) type of broccoli, you will have less of a problem, since it is continually producing smaller florets. This requires a bit of customer education on your part, to entice your customer away from the big heading varieties of broccoli (that are good for one, or maybe two cuttings, and then are worthless) to the other varieties. This is possible, because these less marketed broccolis can be more flavorful than the ordinary variety.
I've grown this
brocoletto di rapa which is prolific with the small broccoli florets and this
broccolo spigariello, which is more of a leaf type that is best in soups.
Heading broccolis and cauliflowers belong in the same category as determinate tomatoes: crops engineered to be grown and processed on a production line, with as few field passes of the machinery as necessary. That's neither permaculture nor good tasting. But it is what big agriculture has conditioned the public to accept.
