Overview. Burr oak, also spelled bur oak, is a tree with many striking features, including crooked branches, large leaves and big acorns.
Crown Rot. Crown rot is often the cause of splitting and oozing near the base of an oak's trunk. Caused by one of several types of fungus, crown rot causes the tree's leaves to turn yellow and wilt, and the small branches to die back. It also causes lesions on exposed areas of large roots and the trunk base.
