Concord grape problem #796704
Asked June 19, 2022, 3:59 PM EDT
My concord grape is in its 3rd year, I believe. It produced a small crop last year but this year is withered. I have not applied any glyphosate or other chemical anywhere near it. Is the extension still accepting samples and would that be an option for me? Photo included.
