Fungus on Carved Oak Stump: Slow Decay with Bleach Treatment

A 350‑year‑old oak stump carved into a castle now hosts fungal fruiting bodies. The fungus is inside the wood; surface spraying with 1:3 bleach:water kills surface spores and slows decay. Cut off the fungal layer first, then treat. Won’t stop internal rot, but buys time for the carving.
