Overwintering Red Banana
Can someone advise me on how to overwinter a red banana tree? I've grown it in a pot over winter and it is a nice size but not "adult size".
I've brought it into the garage now (we had one night of frost, I hope that didn't damage it), wrapped the pot with bubble wrap and stood it on a sheet of celotext. I cold-proofed the garage as much as I could but I think the garage door is not good at all and has lots of gaps, which means it gets very cold in there (if not as cold as outside? - I'm going to do what I can to the door). The garage has a window so daylight will get in.
Now I heard two versions: One was to just cut the leaves and the other one was to cut the stem back to about 2 inches. I would like the tree to grow bigger next year and not just reach this year's size, so which is the best way to go about it? Does anyone know what temperature the red banana can take or if I need to bring it indoors entirely (we live in a tiny cottage and have no or not much space indoors really)
