Now you're in trouble. You said that nasty "W" word. I remember dreading those days. Canadian winters can be so brutal. That's why we're south in the sunny tropics. Except now is our winter, rainy season when everything gets soaked every day. Your bananas should survive as long as you don't too many hard freezes without snow cover. Our bananas have already given us our fruit for this year. But we don't have to cut them back for cold weather. I wish you lots of good luck, because there is nothing like having our own bananas.
