I'm not familiar with clumping bamboo. It's always a neat plant to look at, but all bamboos I've ever seen growing have been next to impossible to contain. My understanding of most bamboo is that it has a relatively shallow root system. Not sure if that's correct without more info. Could that clumping bamboo be confined by sinking one of those Rubbermaid cattle troughs - providing whatever drainage the bamboo might need, of course. Would that be enough to keep it in a specific area? Lots of work, but those rubber troughs last for years and years even exposed to direct Texas sun. They should last a long, long time. I'm just curious about the clumping type.
