Hi
This is my first time growing cauliflower- when I was a kid, I seem to
remember my mother tying up the leaves around the head to keep it "white", I
read this is not necessary with some of the new varieties. The kind I bought
is Brassica oleracea, it says the wrapper leaves provide coverage but do not
envelope the entire head, allowing for good air circulation. So, do I tie
the leaves or not?
Thanks

Friends in upstate New York tell me that tying heads of cauliflower is only for
cosmetic purposes i.e. to get that pure white head, Otherwise it discolors
slightly. Here in the sunny south, it discolors a lot ie turns greenish purple
and develops a strong flavor so we have to tie all varieties.
