I have a grapevine that is about 5 years old. The 1st 2 years it was good, didn’t let it set fruit. 3rd year rabbits ate it down to 5” but it still had a leaf & it grew back nicely. This year & last it got grapelettes but when they were about smaller than a pea, they all turned dark & died. Felt like rocks. I think it’s black rot but not sure. This year the turned dark rust color but again mummified. This happen so all the bunches. I cut the vine back to about 24” and tried to rake up any fallen mummy berries. What is the disease, can it be treated, & should I just pull the entire vine & plant a new one elsewhere? I do have several other grapevines but they are spaced far away from this one. The pics: 1: most leaves were still viable except for some leaf miners. 2. Mummified grapes. 3. The entire vine growing on a trellis & over the fence into neighbors yard. It was beautiful. Thank you, Patricia
