Magnolia trees are not often eaten and damaged by animals, but it can happen. Hungry animals will eat the bark or possibly even the foliage if other food sources are not readily available. Foragers like deer and rabbits are the most common animals that damage Magnolia trees. Evergreen Magnolia trees are at more risk since they retain their foliage during the winter when food options are limited.
According to Rutgers University this plant is Seldom Severely Damaged on their rating scale from Rarely Damaged to Frequently Severely Damaged. Significant damage to Magnolia trees is rare but still possible.
Keeping Deer Away From Magnolia Tree
If animal damage is a concern, plant Magnolia trees within a fenced-in area or near an area often populated by humans to deter deer, rabbits, and other animals. Wrap the trunk of a Magnolia tree with a tree guard to protect it from buck rub. Use a wire cage secured by stakes to keep other foragers away. Evergreen trees are more likely to sustain damage in the winter when other food sources are scarce.
Will Magnolia Trees Come Back After Deer Eat Them?
Magnolia trees that sustain limited damage are likely to recover. The more severe the damage, the more it will impact the tree's long-term health. Remove damaged sections and fertilize the plant to promote new growth. Ensure the tree receives plenty of sunlight and water. Providing ideal care will help the tree recover as quickly as possible.
