We moved here a couple years ago, and sadly I gave little attention to one side of the house. I discovered this awful viney thing that looks diseased, is very thorny, creeping through my siding and even into the foundation of the house, and has a root system that seems endless. I tried to dig it up last spring, and after much digging and pulling, managed to break off a piece of the root that was probably 3-4 feet long. I mentioned this to a lady I work with and she suggested pouring diesel fuel on it. I am desperate, but that seems drastic. Plus, we have very...volatile neighbors whom I suspect would take serious issue with me doing that. Any suggestions or experience with something similar?
