Cedar apple gull fungus
http://planttalk.colostate.edu/topics/insects-diseases/1450-juniper-hawthorn-rust/ will give you information about orange galls you may be seeing on your juniper.
The first part of plant diagnostics is to identify the plant. Would you please send us a photo of your juniper tree and a close-up of the gall you see? Are there apple trees nearby? What do those trees look like? What do their leaves look like? Photos will help us identify the problem so you can treat it effectively.
What you are seeing could be a fungus, Cedar-apple rust (Gymnosporangium juniperivirginianae), which requires two hosts. The life cycle is explained at http://www.missouribotanicalgarden.org/gardens-gardening/your-garden/help-for-the-home-gardener/advice-tips-resources/pests-and-problems/diseases/rusts/cedar-apple-rust.aspx
Hope to see your photos soon, Jessica.
