Two years ago, I had my cucumber and watermelon vines shrivel from the bottom. Moved the crops last year, but it happened again, and also happened to my pumpkins and gourds in a different part of the yard. I have heard there is a soil-borne virus that could be responsible. Is there any way to get rid of it? Only cucurbits are affected. Grew sunflowers and morning glories in the same spot last year and they were fine. Is there a cure? Thank you!
