Re: How fat can a banana stem get in zone 6?
If they stop growing completely at 53F, then there's still another month of growth and they are still putting out around 1 leaf per week getting a bit larger each time. I expect them to top out at around 4-5 inches in diameter this year and I'll probably cut them down to around 2ft, then wrap them in blankets, trash bags, layers of leaves and tarp the whole thing to try and protect some of the psuedo-stem to hopefully give it a chance to come back next year.
I think the corm which is 1ft underground is already around 6 inches in diameter so I think there's a chance of survival here. If they do make it through the winter, I'm hoping for them to approach the 7-8 inch range next year.
