I have 4 tubs of bamboo. Firstly let me tell you that they are messy, ie: they will drop leaves, which can get into your nails when cleaning up,ouch. Also, they will eventually become root bound in any container, (I am currently trying to remove one from a concrete trough, after 2 days I cannot move it, so will have to pay a strong man). Normally I put the containers onto their side drag the plant out and then saw it up to replant what I want. They will tell you when they want water, the leaves will roll up. They can be attractive if you cut the growth off the bottom canes so that you can see the lovely shiny colour. but it doesn't make any difference to the growth etc if you don't. I never feed mine they like it rough
. As to the varieties, have a good mooch around your Gc and growers. I do not hve to cut mine down at the top because the container will restrict the ultimate height. Mine reach about 6/7ft including the container . Also Google specialist growers, and if in doubt, ring them and ask. They are always happy to share knowledge. My personal favourites are the golden bamboo. Good Luck, and tell us what you decide in the end.
