I have what we always called
I have what we always called "saw biers" and they are taking over my patch of crape Myrtles and Azaleas. The vine is full of biers and have an underground runner. I have heard that they have to be dug up but I am unable to dig. What can I do to kill them without killing my shrubs. I'm about to the point of having them all cut down to the ground where I can just mow over everything.
