Troubleshooting
Snowy mespilus problems — and how to fix them
Snowy mespilus (Amelanchier ovalis) 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.
Fire blight
Bacterial infection causing blackened, wilted shoot tips with a shepherd's crook curve. Remove infected growth promptly, cutting well into healthy wood; disinfect tools with 70% alcohol between cuts.
Bird predation of fruit
Berries are highly attractive to birds and can be stripped before ripening. Net individual branches or accept sharing with wildlife; berries ripen unevenly over 2–3 weeks, allowing phased harvesting.
Leaf spot (Entomosporium)
Red-purple spots on leaves in wet conditions, especially on stressed plants. Improve drainage and air circulation; rake and dispose of fallen leaves; apply copper fungicide preventively if recurring.
