True Cedar (Cedrus) : Needle blight
(revision date: 4/23/2014)


Biology
Certain fungi have been associated with needle blight on Atlas and Deodora cedars. In spring, infected needles turn a tan-pink color. The blight may be only on the new shoots or may also affect last year's growth as well. However, the discolored tissue does not affect entire branches. Shoots will die and needles will drop from the plant from June into August. The following spring and early summer, small, black fungal fruiting bodies may be seen at the base of dead needles and along the stem of the killed shoot. The fungus overwinters in dead shoots. The blight is more of a problem in years with prolonged wet, cool springs. Similar symptoms have also been observed without the association of fungi.
