Every fall, the leaves on my large Western red cedar (Thuja plicata) in my yard start turning brown and I worry that I am about to loose it. But then in spring the tree looks very healthy, what is happening?
The red “flagging” branches observed on the healthy cedars in fall is normal leaf senescence. For information on what cedar flagging looks like refer to the WSU Hortsense web site and from the menu bar, click “Ornamentals”, then “Cedar”, and then “Cedar flagging”. Double clicking on image should enlarge picture.
