|Our Evergreen Aboratia trees are turning brown and dying.They are not newly planted,about 10' tall.They are turning brown on top first then working its way to bottom. I don't notice any pods or insects?
|If you find no bagworms in the tops of your arborvitaes, the problem could be related to cold weather (the newest growth is at the top and is more susceptible to cold damage), or the problem might be the result of root rot. Soggy soils can suffocate roots which will show up as dying foliage and branches. Since it's difficult to diagnose a problem without seeing it, try taking a sample of both the live and the dead foliage to your local cooperative extension office. Helpful folks there can rule out disease and insect problems by looking at the samples under a microscope, and they can offer some solutions to the problem. Contact Rutgers Cooperative Extension, 1623 Whitesville road, Toms river, NJ 08755-1199 phone (732) 349-1152. Best wishes with your arborvitaes!
