Gardeners, I gather the large outside leaves of the cauliflower and ties them together like the neck of a bag. I use cloth strips for rags. The old timers called this "blanching". If you don't blanch, the curds will turn several colors, purple, green or yellow. They will also get very hard and lose flavor. I can't lay the leaves on top of the head. With the humidity here they would deteriorate into slime/mush. I have to recheck my cauliflower after wind events to make sure they are still tied up. Allen Bastrop Co., SE Central TX Zone 8
