Do Arborvitaes change in the fall?

Question

I have a row of about 30 ft high Arborvitae's that gives me an amazing natural privacy fence. They're showing orange colored leaves here and there. I don't remember noticing this before. Is this a natural progression into Fall or is something wrong. And if so, what can I do. I don't want to lose them?

Answer 1

Arborvitaes are evergreens, but like many other evergreens, the color of their foliage may change during the cold weather. Several varieties develop a yellowish/brown overtone to the green in winter. If this bothers you, try growing the 'Techny' variety. It is very resistant to winter discoloration.

It sounds like just fall foliage and nothing to worry about.
