There is another solution, which I have seen in trade Design mags, especially for contract work i.e. Hotels etc. You make a sturdy trough and you put castors underneath so it can be moved; modern plastic castors, about 8 or 10 of them. You put good compost in the trough and plant a hedge. Other people on this forum could advise you about what is evergreen and fairly shallow rooted.
