Are you sure it's not just seasonal? I've just written a blog about vines, and most of them are about the leaves chaging colour...autumn is upon us!

Having suggested that, I know nothing at all about real grape vines - only ornamental ones. I hope that another member may be able to offer other ideas for you.

Firstly, are your grape vines inside or outside? are they white or black? A serious complaint could be red spider mite but if you can give me the above information I may be able to tell you other likely reasons.

hi bob, they are green, i guess thats the white one lol, and they are outside, i have looked at them and cant see any sort of red mites or anything else on them, thanks for the reply, any help you can offer would be great.

My neighbours vines are still green and not losing leaves yet. Any chance its a nutritional issue? I assume there is no white mycelium on the leaves.

As Shatc4 is saying is there any Botritis on the leaves and fruit or downy mildew which can be related to potato blight.
