Sheridan is a strange case. It appeared to be healthy and doing fine for two years. It had healthy grapes, and then, suddenly, overnight, all the leaves on the entire vine wilted and died. You can see the leaves just hanging down. It was a real shocker and disappointment.

Other vines on the same grape arbor were unaffected.  Since we grow everything organically, there are no poisons on our property that we are aware of. Perhaps nematodes or voles were the cause. It remains an intriguing mystery. In any event, I decided against replanting since Sheridan is categorized as a "very late" ripening grape, i.e. December. I have since found out that varieties categorized as "late" do not ripen on our site, so  "very late" would not work for us at all.  Zone 4.
