black bamboo from what i gather is not particularly hardy in UK but given a warm spot will probably do ok......i'd look for somewhere out of full sun but not completly shaded.....2 foot diameter is not very big for a healthy bamboo...the best container i found for the price was some black plastic things from homebase with more like 3 foot diameter...you need to leave a gap of at least 2 or 3 inches between the top of the container and the top of the compost...when watering you need to fill this gap with water....drainage holes needed of course...you need to water at least once a week ..preferably twice...dont try separating the roots...feed it through out the growing season...last winters very mild december and january followed by a very cold february was not ideal for your bamboo...they very classy though black stems...good luck..!!
