Yellow Fungus on Pear Tree Bark: Identification and Management

A pear tree of unknown age has developed a yellowish fungal growth on its bark. Last year it bore abundant fruit, but this year no fruit appears. A nearby fig tree shows similar symptoms. The yellow fungus likely represents a wood-decay organism, often called shelf fungi or conks, which indicate internal decay that progresses slowly over years.

Understanding the Issue

These fruiting bodies emerge after years of internal colonization. Unfortunately, no cure exists for established wood decay. Management focuses on reducing tree stress through proper fertilization, adequate watering, and preventing further wounds.

Recommended Actions

Submit clear photos of the fungal structures for more precise identification. In the meantime, maintain tree vigor with appropriate watering and fertilization. Remove any dead or hazardous branches. Accept that the tree may decline gradually; monitor for structural instability that could pose safety risks.
