I have ordered several PHYLLOSTACHYS NIGRA (Black Bamboo) plants and
I would like to keep them in containers.

What sort of soil do they prefer do they like damp or dry conditions
any tips on keeping these healthy appreciated.

I've got another Bamboo in a container (can't recollect its name just
now) it is about 6ft tall and seemed to be doing well until a couple
of weeks ago when its leaves suddenly turned brown. It looks as though
it is dead, no sign of new shoots at all, it is not pot bound as I
have checked that. Sometimes in the mornings the leaves seem to have a
little bit of green in them but then that fades away during the day.
Any ideas as to what could have caused this is it worth keeping ie
will it send out new shoots from its base?

Any advice appreciated.

Thanks
