I have discovered that I have what appears to be a wild grape plant mixed in and among some multi flora rose and honeysuckle. I would like to attempt to rescue this plant and use the grapes produced. Were I to cut the plant back would it recover? How far back to cut it? When to cut it back? Advice? I also want to keep the other "weeds" as they not only look nice but they also screen out the neighbors view of my yard.
