Cedar Apple Rust on Windbreak Cedars: Manage Apple Proximity

Old Cedars Have Brown Lumpy Nodules; Owner Worried About New Fruit Trees

Nodules on one cedar, few on neighbor. Berries present. Fruit trees ordered nearby.

Expert Identification

Nodules are Cedar Apple Rust (fungus). Minor on cedar, serious on apples. Fungus needs both hosts. Common practice: don't plant cedars and apples close. Some apple varieties more susceptible.

Follow-Up

Crabapples also get it. If keeping crabapples, monitor; decide tolerance level.
