I've just moved house and in our back garden is a fairly large palm tree (pictures), the problem is that I'm not sure what it is and therefore don't know how to look after it and make sure it makes it through winter in the south-eastern UK.
All the research I've done so far seems to suggest it's a banana palm but I'm not sure what type. Info on several possible species say they will be fine over winter, but a few also say that it will need to be protected from frost, so I'd like to make sure I'm doing the right thing.
