Adapted from Please help me diagnose deodore cedar tree problem. - Ask an Expert "The blight is likely to be a needle blight fungus (of the genus Sirococcus or Kabatina). These kinds of needle or leaf blight fungi tend to be worse with a long wet spring season. The spores are dispersed by splashing water at the same time that new growth emerges on the cedars. New growth and twigs near the tip are most affected and trees usually recover later in the summer." For more information on the blight and possible treatments, see the article in the PNW Plant Disease Handbook at Cedar (Cedrus spp.)-Needle Blight
