I have a few cedar trees and 2 of them look as though they may be dieing. I have no idea why but is there something I can do to prevent them from dieing or is it to late. They are turning brown in color where as the other trees are looking greener then the 2 in question. The 2 trees are in different locations so I dont suspect that they were damages or anything just kind of odd that they would die all of a sudden. They have been in the ground for 2 years now and have been fine for the entire time until now. Any help would be great. Anker.
