"Emery Davis" asked:

What are the moisture requirements for Phyllostachys nigra? Any
particular soil issues? And it really clumps and doesn't spread?

P. nigra, as do most other bamboo varieties, won't do well in soil that is
constantly too wet or too dry . It usually is compact, and
apart from cutting down the old branches requires very little maintenance.
They all prefer lots of organic matter, not too well matured. You don't need
to clear away the old leaves as these add perfectly to the natural ground
compost. Bamboos thrive in a full sun aspect but will also tolerate semi
shade.
