Cedar-rust complex is caused by a fungus that requires two hosts—juniper plus apple, crabapple, hawthorn, or quince—to complete its life cycle. This disease is found anywhere that junipers (also known as red cedars) grow and can cause considerable damage when both hosts are grown near each other. This fact sheet details the causes of cedar-rust rot, highlights the effects you can expect, and offers effective means of control.
