Well, its possible - but not for long. You might get away with having it in a pot for a couple of years or 3, but inevitably it will start to suffer being so contained. Use John Innes No. 3 potting compost, or a Tree and Shrub mix.

If it's a pot-grown plant, you can do it at any time. I'd say you'd need a very large pot - possibly a half-barrel?
Probably JI 2 or 3 would be the best option if it's going to stay there. I wouldn't feed it until the spring, and you might need to bubble-wrap the container in severe weather to protect the rootball.
