Hello,
I have 3 well established arborvitaes in my yard- about 20 feet tall. 2 years ago, during heavy rains- one was felled due to soggy ground combined with heavy winds. It was immediately propped back up, tied and fed on regular basis. As of late, its has been turning a pale green color, loosing a lot of needles, and browning in certain spots. I am fearful that the root system has been permanently damaged...Do you think that may be the case? I would be happy to send a picture via email if that would help...
Thank you, Tom
