Oldhammi Invasion: Solutions?
Several years back my neighbors planted Oldhammi too close to a shared fence. It has been invading my side and for awhile I would just break off the stalks as they rose. But now it has done some damage to my part of the fence, and damaged my drip system hoses.
My landscaper says I should tell the neighbors they need to create a space and/or barrier between the fence and bamboo on their side. Also, that I should cut away all the roots (with a circulating saw).
But if the neighbor won't take responsibility and act to prevent future damage and invasion, what are my choices for acting unilaterally to keep this from happening in the future? One possibility I've thought about is paving over the area, which is essentially a pathway between the front and. back of the house. Is there a way to dissolve the stumps? Other ideas? I'd like to know all my options before I make a decision.
