Try and keep the plant as warm as possible to let the fruit grow. Plus in the springtime you could go ahead and remove the 5 pups growing around the mother tree and plant them on their own. They should do fine through the winter. It sounds like you have had no problem with the mother plant over the past few years. The mother will only fruit once. Yes you can eat the bananas. They will need time to ripen and grow. Thats cool that you got nanners though. Congrats. Rob
