I have 2 second year vines. They flowered and began numerous clusters. In the last week the individual grapes have begun "drying up". The vines look great - leaves appear healthy. We've seen a few earwigs on the vines - looks like they might be eating them? or something else? If earwigs, what do we do to prevent next year?
may be a lack of boron in your soil grapes need it for set, you can apply it as a foliar spray (20 20 20 with micro nutrients) or as aground application in august be careful over use is toxic to vines
