Only thing you'd have to worry about is frost getting into the ground around the banana. Thats the issue i can see here. In snowbelt areas to the north and east, the ground never freezes, but here it isn't always the case. I might bury a temp probe this winter under a couple of bags of leaves on the lawn and just see what it does. I've got a digital wireless thermometer with one of those 10ft probe attachments that i could use for this.
