Someone was getting rid of their mature banana trees on Craigslist, so I swooped them up. I had to dig, I pulled out about 3 large ones (8-10 feet) trying to take as much soil with them as possible. It's early winter and I'm in Portland OR (zone 8). I know this far from an ideal time to transplant, but leaving them in the ground until spring wasn't an option. My only question is, what's the best option from here? Should I get them in the ground immediately and mulch/insulate them or should I pot them for now and overwinter them in the garage until spring? Winter has been mild so far, but wet, and sometimes we get snow in February. Thanks in advance for any tips!
