I feel sorry for those babies, but odds are they will do great in spring, since there have been some hurricanes and other misfortunes in your garden's history. I'm a big fan of your Ae Ae freedom and Ae Ae distribution policy (or what it once was - giving pups away).
I remember that long time ago, when I started being crazy into bananas, I foung your website and saw Mediahound's picture with a new Ae Ae naner there, made my heart warm up a little bit.
Don't worry, some of us can't even grow bananas, yet we fight and struggle, some bananas undergo strong frosts, cold rains and other bad weather, yet they somehow manage to survive. It will all end well. Cheer up, pal.
Nature will find it's proper course of action.
