|How do I know if a juniper shrub has twig blight? Shrub is showing green in front and brown/bare in back. What can be done?
|There are any number of reasons a juniper would turn brown, but since it seems to be all on one side I would suspect a physical cause such as lack of sunlight if it as against a building, perhaps an overspray of herbicide if that side faces a lawn area, or perhaps a dog who marks that side repeatedly, or perhaps uneven watering pattern and so on. If you can't discover a cause for it, then it might be a disease or insect problem in which case you might wish to take a sample to your County Extension (454-0900) for a specific diagnosis and suggested controls.
