Troubleshooting
Silverberry problems — and how to fix them
Silverberry (Elaeagnus commutata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Aggressive suckering
The plant spreads rapidly via root suckers and can be difficult to contain; remove suckers promptly at soil level or install a buried root barrier when planting near borders.
Fungal leaf spot and honey fungus
Wet conditions favour fungal leaf spot (Cercospora or similar) and honey fungus (Armillaria); ensure excellent drainage and remove infected debris promptly.
