Good luck with your nanners!
I'm from Hickory, to your west. I am kind of curious about your plans to get your banana plants through the winter in the future. That's a lot of banana mats and a lot of digging up plants if you are going to go that route for the winter. This is my first year experimenting with in-ground bananas. For the winter, I have placed wire cages around them, filled the cages with straw, and covered them with plastic. We have hit 29 degrees a few times this winter. I checked on my plants, and they are still alive. I wonder how they will do when we get 24-72 hour periods of below freezing temperatures.
