Just about anything will steal your grapes. Birds, racoons, squirrels, and even deer. Sure stinks when you walk out in anticipation of harvesting and find them gone. That happened to a lot of my corn this year. Had a coon who could shuck that corn and clean dozens of cobs overnight.FJ, we are new to growing muscadines. We had a nice small crop growing. We went out one evening to see if they were ready and every single one of them was gone. What would have done that and how do you prevent it?
