Sawtooth Oak Dead Limbs: Natural Shading, Not Disease

Leafless limbs with orange fungus on a sawtooth oak are simply shaded out by higher branches. The tree aborts lower limbs that no longer contribute energy. The fungus is secondary, colonizing dead wood.

Remove dead limbs correctly: cut at the branch collar (swollen base), not flush with the trunk. Flush cuts create large wounds that may never heal. Wound dressings are unnecessary and not recommended.
