Thank you both, for your replies. I am new to bananas and will take any advice I can get!
I bought two basjoos from FL that are on the way, but I also know of many yards with huge clumps of them as well. This was why I asked about transplanting them. A little door knocking can't hurt, right?
it's really weird asking for advice, as I'm used to giving it on dawn redwoods, so now I know how it feels!!!
