Hi. I have received a lot of information from bananas.org. Whatever you do, dont cut the pseudostem back or it will delay the fruiting. I stored mine in a friends unheated garage and covered mine with blankets and it did well. Since it will be dormant, water it rarely and very little, just enough to make sure the roots dont completely dry out. When you plant your bananas in the ground be sure to have well drained soil and you can use a well balanced fertilizer. But lots of organic matter is perfect. Bananas also like fertilizer high in potassium. I hope that helps a little

Thank You
