12 yr old emerald green cedar

Asked May 17, 2020, 4:00 PM EDT

My emerald green cedar started to dry out from the top and is now turning red. These are at least 12 yrs old. What is the cause ? Will the affected cedar affect the other cedars. What to do to save them. I have 3 affected.

Thank you for your question. it is difficult for us to diagnose the cause of a plant problem without knowing your location, and what care you have given the tree. We don't know how much rain you have, what your soil condition is, or how often you fertilize and give supplemental water to it. And, without a location, we don't know what type of diseases and insects are in your region. Do you have a local horticulture university or other plant program with local experts? Thanks!
