Can Treatments at Planting Improve Noble Fir Seedling Survival?

Noble fir (Abies procera Rehd.) plantings for Christmas tree production have experienced poor to variable survival over the past decade. With little ability to provide supplemental irrigation, Christmas tree growers investigated first-year seedling survival results in response to a variety of pre- and post-planting treatments, root dips, and foliar sprays. In three separate trials, wood chip mulch or shade screens increased survival (though not consistently) in moderately dry summers in Oregon. None of the dips, sprays, or amendments, however, resulted in significant survival improvements.
