Decay Fungus Conks on Red Oak: Not an Emergency

Overview

Atlanta red oak: fungus at trunk base, brown leaf spots lower canopy. 8 ft from house. Two opinions: remove (hollow/rot) or remove + grind (prevent spread).

Reality: Decay Fungus Fruiting Bodies

Enter through wounds → infect dead inner wood only.
Don't attack living cambium → tree health unaffected.
Hollow trees live decades.
Risk: limbs may weaken/break over time.
Not contagious—spores need wounds to infect other trees.
Chips/stump harmless.

Recommendation

If canopy green/full: don't remove.
Fertilize: 10-10-10 at 1 lb/inch trunk diameter (fall + spring).
Monitor for limb failure—then reassess.
Get unbiased opinion: GA Forestry Commission forester (not tree service selling removal).
