Arborvitae well established dying
I have noticed many very well established arborvitas dying. These are anywhere from 4-10 years in the ground. I also noticed many others around the Clackamas county area doing the same. Is there some kind of a problem that is airborne right now? Any fixes? Thanks!
Clackamas County Oregon
Many kinds of trees beyond arborvitae are dying. For the most part, the reason is that several recent years with lower than normal rainfall and generally elevated temperatures have stressed the plants beyond their ability to survive. This article explains the process: http://www.oregon.gov/ODF/Documents/ForestBenefits/interactionofdrought.pdfIf you have concerns about your own trees, I suggest you contact several Certified Arborists for onsite evaluations. Arborists such as these must pass and exam and then must accumulate continuing education credits.
