Oh, man, at least I'm not alone in my pain. I found an almost identical thread to the one I started here on another forum I didn't know existed.
Help!! Squirrel's eating my banana's - Banana Forum - GardenWeb
I guess the bigger question in all this is the curious one of WHY the squirrels now have put banana plants on their menu? I live in North Central Florida, and you can't spit down here without hitting a 100-year oak tree, so it's not lack of food.
Somehow, these b-tards are morphing into the Borg or something...
