Arborvitae dust

5 years ago

I have several emerald green arborvitaes surrounding my property. Today while working outside I shook some and a very fine white dust went into the air. None of the trees look like they have anything on the stems or needles at all, and they appear healthy. I took my backpack blower and blew them all off, now no more dust comes off. Any ideas on what this is?

thank you
