My Contained Garden book says you'll need a pot 16-24 inches wide by the same deep. I'd wait and plant in spring because the forecast for this winter is bad, and if the pot freezes for any length of time, the plant will die. Best if you start off with a smaller pot and move it up into the bigger one after its grown on - I know that's difficult because it'll be a climber though.

thankyou for that,that tells me every thing i need to know,cheers.
