Troubleshooting
Downy Serviceberry problems — and how to fix them
Downy Serviceberry (Amelanchier arborea) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Cedar-serviceberry rust
Orange rust spots on leaves and fruit, alternating with junipers and red cedars. Remove infected tissue and avoid planting close to those hosts where rust is a problem.
Birds
Birds eat the ripening fruit fast, often before you can pick. Net smaller specimens or accept it as a wildlife tree if a crop is wanted.
Powdery mildew and leaf spot
Fungal foliage diseases in humid summers. Improve airflow, clear fallen leaves, and choose an open, sunny site to keep leaves dry.
Fire blight
As a rose-family plant it can suffer bacterial fire blight, causing blackened, wilted shoot tips. Prune out affected wood well below the damage, disinfecting tools between cuts.
