My grapevine has been growing in this same spot for a long time, longer than 6 years I'm sure. This year we have a lot less foliage, a lot less grapes growing, most of the branches are dead. But what I do have I see some areas of concern...see picture. Can anyone tell me what this is and if there's a treatment or am I looking at loosing my grapevine? Also, we recently had an oak tree cut down because it had some kind of fungus and it died, not the same thing but I wonder if one might have something to do with the other. Thanks.
