Sick looking Cedars?

Have you noticed the western red cedars in your neighborhood showing lots of brown fronds lately?  In most cases, these trees are not really suffering from some horrible tree disease or pest but simply shedding their old foliage.  This annual phenomenon is called “cedar flagging” and is much more noticeable this fall due to our prolonged summer drought.

Most of the dead “flags” will be blown off with our first good wind storm and the trees will look as healthy as ever.

For information on cedar flagging, see WSU Hortsense at http://hortsense.cahnrs.wsu.edu/Search/MainMenuWithFactSheet.aspx?CategoryId=1&SubCatId=3&PlantDefId=143&ProblemId=739
