True Fir: Current-season needle necrosis
Current-season needle necrosis affects noble fir and grand fir. The cause is unknown, but appears to be a cultural problem due to a mineral deficiency. Shortly after growth begins, the current season’s needles develop brown bands. These bands later turn dark or reddish-brown, and may expand to cover the whole needle. The reddish-brown needles drop from the tree. Current-season needle necrosis is not specific to a particular area on the tree. It does not spread between trees.
