Potato vine problem
Stupid teen mistake - digging up some of my grandmother's potato vine and transplanting into the yard - that was twenty years ago and despite my attempts to dig up the tubers it has taken over my flower garden. I know that Roundup should kill it, but if I spray it I would think that everything else would be killed as well. Will I have to dig up the whole garden and try to find the tubers?
If so, what time of year is best to deal with it. I am in the mid South. Thanks
