Troubleshooting
Callicarpa americana problems — and how to fix them
Callicarpa americana (Callicarpa americana) 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.
Poor berry set in shade
The signature autumn berries are sparse in low light. Site in full sun and ensure a nearby plant for cross-pollination to maximise fruiting.
Winter dieback in cold zones
Stems can be killed back by hard frost near its northern limit. This is normal — cut back to live wood in late winter; it flowers on new growth.
Leggy, sprawling habit
Left unpruned it becomes open and floppy. Prune hard in late winter to a low framework to encourage dense, well-fruited new stems.
Leaf spot in wet seasons
Fungal spotting can appear in humid, crowded conditions. Improve air circulation and avoid overhead watering; rarely serious.
