Arborvitae die-off #873453

Asked June 17, 2024, 1:49 PM EDT

A stand of over 100 Arborvitae on my property in Clatsop Plains, on the outskirts of Warrenton are beginning to die-off and I can't find anyone who knows what to do before they all die. Is there a disease that just struck? The shrubs have been on-site for about 20 years - is this just inevitable - old age?

Expert Response

Will you please send some photos of the row of Arborvitae as well as of a couple of the  individual plants so I may see the progression of the problem.

Thank you
