Last yr I bought 2 musa's & planted them outside in pots. When fall came I brought 1 pot in the house,the other 1 I dug up &wrapped in newspaper & kept in the shed. The 1 in the shed died. The house 1 survived all winter. I didn't water as much, then brought it out in May. I took pix in Aug & again today.I have about 5pups which I don't think I will divide until spring. I will be bringing it in again soon. {{gwi:420133}}lt="Banana 8/08">

The first banana is Musa Dwarf Cavendish(not cold hardy), and the second one from jrzgurl is Musa Basjoo (very cold hardy).
Not sure what would be best for overwintering, but safe is ussaly better than sorry, maybe try to make room inside in a window.

tropicallvr - just to clarify, is my banana a Musa Dwarf Cavendish? Not sure because jrzgurl has 3 photos, though I guess rereading it she has 2 Musas. That would be great to know what kind it is!

tropicallvr has a great eye. I was going to say the same thing, but tropic beat me to it.

ejr2005, your banana does almost certainly look like a Dwarf Cavendish. The term musa is part of a genus meaning a class, kind, or group marked by common characteristics or by one common characteristic. So musa is a broad term. One way to tell full size varieties and dwarf is by looking at the stems on the banana stalk in reference to how far apart they grow from each other. Full size varieties tend to have long slender branches farther spaced apart from each other. My Super Dwarf Cavendish has stems that are fat and broad and grow very close to each other height wise. On to your questions.

jrzgurl posted pics of what looks like 2 different potted bananas. Both pots look like basjoo bananas.

It wouldn't hurt to leave it in the sunroom. Also you could store it in a darker, cooler room as well but water less often.

Do not fertilize your bananas in the winter. Keep watering to a minimum. If you keep your banana in a sun-lit room then water only when the top inch or two of soil in the pot is dry. You can also store the pot in an unlit room that is cooler (not freezing) and water once a month if that.

You can keep it outside till just before the first frost. A frost will not kill your banana, but being that it's a cavendish variety, they do not like any kind of freezing. A frost will tinge the leaves and turn it brown like the bottom leaf in your picture, but thats about it. The plant will survive. Tomato plants are MUCH more sensitive to frosts than bananas.
