I seem to have some disease (or lack of nutrients?) on my concord
grapes. The fruit, which is not yet ripe, is getting dark spots and
areas on it. I had this same problem last year, I thought maybe it was
due to the heavy rains we had.
Figuring a picture is worth a thousand words, I took a photo of some of
the fruit: http://www.blackcatsystems.com/concordgrapes.jpg
Maybe someone can identify what the problem is, and what some solutions
might be? I was looking forward to making some grape juice this year :-(
