Title: Douglas-fir survival and growth in response to spring planting date and depth

Author: Strothmann, R. 0.;

Date: 1971

Source: Res. Note PSW-RN-228. Berkeley, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station. 6 p

Publication Series: Research Note (RN)

Description: Douglas-fir seedlings were planted by four methods in late February and late March on hot, south-facing slopes in northwestern California. Besides standard planting, the techniques used included deep planting at two different depths, and shading the lower stem. The differences in survival after 3 growing seasons were not statistically significant, but deep planting had helped height growth. Excellent survival in all treatments was probably the result of good stock, careful handling and planting, proper site preparation, and timely rainfall the first spring.

Keywords: Pseudotsuga menziesii var. menziesii, planting depth, seedling survival, height increment
