It will be hard work to dig up and move...I have done so successfully lots of times on Bamboo's not so big. You could maybe get at least 4 "new" plants from that one, I "saw" mine with an old bread knife, its very hard word tho'...brute force and a temper works wonders...good luck. Oh ... if its leaning, try planting it leaning in the opposite direction, that may compensate for the wind direction, I'm not sure but worth a try with one or two of them to compare, if it works dig up the others and get them leaning too...I would move Bamboo any time, but if its hot and dry, water water water...
