How to stop Bamboo spread?
Running bamboo is extremely difficult to control (as you are well aware!). You can try installing a barrier at the property line or at the edge of where it currently has spread. The barrier could be concrete or steel, and must go down into the soil several feet to prevent the bamboo rhizomes from creeping under it. Others have had success in controlling bamboo by creating an open trench next to the bamboo. Prune off any rhizomes that creep into the trench.
