Question: My trailing junipers are dying out from their centers. What might the cause be?

Answer: That sounds like one of the types of spider mites. Interestingly, this particular mite also is an early one, with the damage starting even in late winter. You can confirm its presence by thumping a suspect twig (dying but not dead) over a sheet of white paper. The mites will be more visible on the plain, light-colored background. If they’re there, spray with a labeled insecticide. Be certain, too, that the plants are getting full or nearly full sunlight, also that drainage is excellent. Both can lead to trailing juniper failure.
