Last year my grape vines produced fruit for the first time. I knew the birds would go after them, but I decided to hold off on netting them until I saw signs of munching. They just seemed too pretty to net. Colossally bad call on my part. I literally went to bed one night with bunches and bunches of grapes and woke up the next morning to none. My vines were only a few days past bloom, and each grape was no bigger than a pea, so I can’t imagine they even tasted good. Rude birds!
