This wild grapevine may be dead or dyeing. I didn’t check to see if my husband had severed it with his tractor. Corky hates all “damned vines” and has most big ones eradicated, Florida Crackers call these grapes Scuppernongs. They are delicious. I have some young vines trained along a back fence so that when they get enough sun to ripen , I can reach the grapes that the birds and other critters don’t get.
