I have 7 small bananas that I over wintered in the house. Considering this was my first winter with bananas I am very happy that I did not kill them. I did a lot of reading here and tried to do as was suggested. Kept them on the dry side and cool. Well we are getting some nice days and I want to start taking them outside. I know not to just put them out in the sun, but to start slow and gradually extend the time in the sun. But what I am wondering is what is the coolest nighttime temps they can handle without hurting them. After keeping them alive all winter I would hate to do something really stupid now and set them back. Thanks for any advice you can give me.
