I don't tie the leaves up, but break, or bend the closest leaves over the head
to keep off some sun. It works fine for me.

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
