Shearing Systems for Fraser Fir (Abies fraseri) Christmas Trees [PDF]
Plantation-grown Fraser fir (Abies fraseri (Pursh) Poir.) Christmas trees were subjected to nine shearing regimes over nine years in a plantation in western North Carolina (USA). Treatments differed in the year of onset as well as the length of the residual leader (25 to 46 cm).

Optimal Nutrition and Diagnosis for Abies fraseri Christmas Trees in Michigan [PDF]
Abstract Fraser fir (Abies fraseri) is a species with a highly restricted native range that is now planted widely for Christmas tree production throughout the eastern US. The southeastern US has a long history of research on nutritional demands of Fraser fir, but growers in the Upper Midwest have limited locally based nutrition research ...

Recent results of Czech-American fir hybridization research
Fraser fir (Abies fraseri) Christmas tree plantations in North Carolina are infested by root rot caused by Phytophthora cinnamomi. This disease kills almost 100% of Fraser fir material and leaves the soil permanently infested.
