I have two in 15" tubs. Year 3 now. A little slow to get going this year,
but romping away now. Watered daily in hot weather, and heavily mulched.

We have several growing around the house. I don't know how old they are
as they came with the house. Sometimes I think it is the other way round
- inside the virginia creeper there is a house :-) the trunks are around
2 inches wide where they go into the ground. I've no idea how big the
root balls are. I guess they maybe OK in a pot if kept small; it depends
how big you let them grow. If ours were pot based, the size they are I'd
imagine the pots would need watering every ten minutes in the Summer!
