Cedar Hawthorn Rust

A significant leaf disease of hawthorns, similar to cedar/apple rust in apples and  brought on by proximity to junipers and Eastern redcedars. Easily seen due to orange lesions on surface and underside of leaves. Wet spring weather, fog, lack of air-flow through tree, and humidity are contributing factors. Spray treatments can help but usually take several years to be effective. Also, removal of dead leaves and fruit is imperative.
