Interior Needle Yellowing

We have heard from growers in upstate New York about interior needle yellowing particularly affecting their concolor firs. From the trees we looked at on two sites in upstate NY we have not seen any diseases or insects involved, rather just natural fall needle drop.   This is one of those years where the yellowing is  visible and dramatic on many trees.  In some trees it is less noticeable because there is more new foliage to hide the interior foliage that is on its way out.  On some trees the interior needles drop with an “off-green” color which is less noticeable.  This autumn needle drop is also visible on white pines in most years, this year is no exception.

In either case with some strong winds between now and late November the offending yellow needles should be off the trees and they will be ready for the Christmas tree shoppers.
