Effect of Root Form on 10-Year Survival and Growth of Planted Douglas-fir Trees

Douglas fir seedlings were planted with three root form treatments including C-roots ("correctly" planted controls), L-roots, and J-roots. After 10 years, there were no significant differences in outplanting performance between the three root form treatments on a good site in western Oregon. The results are in agreement with those of other studies, which suggests that when no other confounding planting errors are present, deformed root systems play a less dramatic role in subsequent field performance than is generally thought. These results in no way imply that poor planting is acceptable.
