Leaf Spots on ‘Mine‑No‑Yuki’ Camellia After Record Rainfall

The Situation

A camellia in central Arkansas (Zone 7b) developed irregular brown/black spots with gray centers after 30+ inches of above‑normal rain. The owner suspects a fungal disease.

Expert View

The spots don’t match common infectious leaf spots (e.g., Cercospora, Colletotrichum). Excessive rain can cause physiological leaf spotting—edema, nutrient leaching, or minor fungal colonization on stressed tissue.

Immediate Steps

1. Remove and discard heavily spotted leaves to reduce inoculum.
2. Improve air circulation—prune nearby plants if needed.
3. Avoid overhead irrigation.
