Troubleshooting
Japanese Cornel Dogwood problems — and how to fix them
Japanese Cornel Dogwood (Cornus officinalis) 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.
Late-frost flower damage
The very early flowers opening on bare branches in late winter are at high risk from hard late frosts, which brown and kill the tiny blooms; siting against a south- or west-facing wall provides shelter, or plant in a frost-free microclimate.
Reluctance to fruit in part shade
Fruit set is greatly reduced without adequate sunlight — a common disappointment for gardeners who plant in partial shade; ensure at least 6 hours of direct sun daily for reliable fruiting and the best displays.
Slow establishment
Despite eventual adaptability, Cornus officinalis transplants slowly and the first season's growth is minimal; plant in spring, water reliably throughout the first year, and mulch generously — patience is required as the root system establishes.
