Concord Grapes Turning Brown
I moved into a house in October that came with a good size concord grape vine. I didn't really do anything with it as I had so many other projects to work on. For a while it seemed like it was growing well and I had a bunch of little green grapes. A few weeks ago all of them started getting brown spots and eventually just turning brown. I was thinking maybe it was a result of the huge amounts of rain we have had but I really don't know. I now realize that I should have done some heavy pruning before spring but pruning aside is this something that I can avoid next year or have the heavy rains not been good for my grapes?
