Thanks everyone!
Do I have to sink the pot into the ground? I have heard some people say that they do, but other people say you can just grow it above ground. Is it better for the tree if it is sunk in? Or is it just personal preference?
Also, does it matter if I grow it as a tree or a bush? At the garden centre they said it could grow either way. Mine has about 3 or 4 shoots and so looks more like it was trying to be a bush than a tree, but what do people think about that one?
I can try to shield it for winters and insulate it a little, plus I will choose a sheltered walled spot for it to overwinter against a south-facing fence. Other than that, does variety of fig matter much?
Sorry for all the questions. It's my first fig ever and, frankly, I think it might be easier to grow in Italy or somewhere warm but the thing is, I'm in Bucks.
