In the last 2 days, birds have eaten every berry my tall Holly tree that was loaded with berries. Is this harmful to the tree? How long does it take for her to bloom new berries?
Holly berries are quite poisonous to humans and our pets but are relished by birds, including migratory birds, and small animals. They do not damage the plant. Assuming you have a male plant nearby, you should have berries annually. The spring blossom is relatively innocuous but a female plant will turn these into the cheery red berries if pollinated by a male plant.
