One tip given was to sink solid metal "walls" about 2 feet into the
ground
to prevent bamboo species from creeping to mingle with other plants
and
other bamboo.
I guess that would work for a relatively small area. It could satisfy
my concern for uncontrolled spreading and having bamboo become the
kudzu of the Ozarks and me being the stupid jerk that did it. Will
give that some thought.
