Red Oak Fungal Disease


                              animal damage

Thank you. S.F. Mineola


A:  Animal damage like this cause severe injury to trees or shrubs. If the damage is all the way around the trunk, the tree will not survive. To prevent this problem in the future, increase the health of the soil and the tree. This tree is at least 6" too deep in the ground. Its root flare should be exposed and any circling and girdling roots should be removed.
