Hey Tink, those bamboos can be a pain in the seat to contain and get rid of.
We had some on our property a few years ago (came with the property) my DH decided to "get rid of it for good". He used roundup and crossbow to try to stamp it out. Guess what? It grew like crazy the next year and spread to beat the band. It has stayed pretty much in one place till then. To "fix" the problem we had to use our backhoe and dig down about 2 1/2 feet and 4 feet past the boarder of the plant to finally get it out. It's always better to dig then spray
They do make very nice screens
I have read for containing them in my area (zone
and probably the same for you, you have to have either a thick metal or concrete barrier that extends at least 2 feet down to contain the runners. The metal will rust over time though. There are some bamboo strains that stay contained that you might want to research.
I can tell you this, it isn't fussy about where it wants to travel. It would have taken over my little pond in no time at all if we hadn't removed it before installing.
Good luck!
