Black Bamboo in pot
I can't bring myself to plant Bamboo in the garden, I already have too many thugs. But, since I like Bamboo, I have some in a large planter. Unfortunately, it is now too big for the planter and putting up spikes regularly. Is it possible to divide it? I think it's quite rootbound since I can't get the planter to retain water and a lot of the leaves are looking really dry. I don't know what to do.
