I'd give it a go - try to keep the roots intact and prepare a larger than you think you'll need planting hole before you dig it out. But don't do it while the ground is frozen, which is probably is where you are currently - it's even frozen here in London today!

I answered you other enquiry regarding your Cordyline but for this one I would say it is possible having moved one nearly as big myself several years ago. The dense, thick roots make a solid root ball that isn't too exploratory regarding wayward roots so best excavate a trench around this about 2ft 6ins from the base and once exposed you can get under the roots and lift or haul it out with extra hands.

Happy New Year Bamboo :-)

Cheers Fractal, ditto - too tired and cold to care about anything much today, lol
