I have grape Vines growing all over my chain link fence and we love them. We have never pruned them or even cut much. This year they look awful. We don't eat the grapes they r very bitter. We just want them to look nice next year. We have approx 7 roots in the ground. What should we do?

Its very possible to have contracted a soil fungus. You can treat the fungus many different ways. You can do one or more of the following: Use wettable sulfur on the soil around your plants, use need oil to spray on and around them, and for pH control, add dolomitic lime to your soil area. This will help control the pH, as sometimes it can change every few years.
