Orange Jelly on Evergreen: Cedar-Apple Rust

The orange, jelly-like balls on your evergreen (likely a juniper/cedar) in spring are the spore horns of cedar-apple rust (Gymnosporangium juniperi-virginianae).

Life Cycle

• Spring: Orange gelatinous horns on cedar/juniper release spores.
• Spores blow to apple/crabapple → leaf/fruit spots.
• Summer: Spores from apple blow back to cedar → new galls.
• Two hosts required—cedar AND apple.

Impact

• On cedar/juniper: Minor—galls are cosmetic, no real harm.
• On apple: Can cause defoliation, fruit spots, reduced vigor.

Management

• On cedar: Prune out galls in winter (before horns form).
• On apple: Fungicide sprays at pink bud through petal fall (myclobutanil, propiconazole, mancozeb).
• Resistant apples: 'Liberty', 'Enterprise', 'GoldRush', 'Pristine'.
• Remove nearby cedars if feasible (spores travel miles, though).

Your evergreen is fine. The jelly is a spring spectacle, not a crisis.
