Hey everyone. I'm just wondering if anyone can give me some insight on to why my cedar tree is starting to brown. They have been planted for 3 years and are growing great up until now. One of them is starting to turn a very light green, looking even brown in some spots. They are Thuja occidentalis 'Brandon' cedars. The weird part is that this one is the tallest of the 3, but over the past few weeks has changed color where the other's haven't. I can't see any indication of bug's on the leaves or bark. The leaves are brittle yet either.
Thanks!
