Troubleshooting
Buffalo Currant problems — and how to fix them
Buffalo Currant (Ribes odoratum) 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.
White pine blister rust host
Ribes species, including buffalo currant, are alternate hosts for white pine blister rust. In regions with susceptible white pines, planting may be restricted; check local regulations before planting.
Aphids
Colonies on soft new growth distort shoots and cause leaf curling. Dislodge with water, encourage ladybirds, or treat early in spring.
Excessive suckering
Spreads by suckers into a thicket. Dig out unwanted suckers or contain with a root barrier where a tidy shape is wanted.
Leaf spot and rust
Fungal spotting yellows and drops leaves in damp summers. Improve airflow, clear fallen leaves, and avoid overhead watering.
