I am growing a couple of Banana trees in outdoor containers for the first time this year. I am not sure how much protection they will need. One is approx. 1.5 metres, in a very large ironstone urn; one is in a metal container and plant is approx. 1 metre tall. Container is copper and quite thin, although I did line it with some styrofoam when I initially planted it up. Should I wrap the containers with insullation or the entire plant and pot? I suppose leaves and burlap will work, but should I avoid plastic wrap to prevent rot? It would be a lot easier if they were in the ground, I think. I have assured my clients that Bananas can overwinter in Vancouver outside, so I hope someone can advise me on this. Loved the igloo, lichen-growing, polar bear, Great White North discussion. Over here on the North Shore we already have our annual Permafrost going on!
