Help save my grapes! :(

beard_of_socratesMay 31, 2014

Hey all,

I could use any immediate advice from anyone here. I have a grape vine in my backyard that spans the entire trellis. Last year, while new to gardening, it caught black rot; my grapes were nothing but shriveled mummies.

Lessons learned I pruned it back, cleaned the thousands of mummified berries, and applied an organic fungicide before buds opening, once the buds opened, and a couple more times over the following weeks. Looking at my leaves now I'm seeing signs of black rot yet again! Tan-yellow-brown spots, some leaves breaking apart from the middle, and to top it off black lenticels on a few stems. (could be something else though?)

Since it's in the early stage, is there anything I can do, or am I doomed to another year of crinkly grapes? :( Not sure what I can possibly be doing wrong, but if it goes bad again, I may have to simply remove both plants, since the upkeep would not be worth the yield, which I really don't want to resort to because it is pretty on the patio.

It helps I live in Michigan.

Thank you all!
