DescriptionIn 1956 Hallinl reported some observed effects of pruning ponderosa and Jeffrey pine based on the response after 5 years. This report is an extension of those observations, after a 10-year reexamination of the experiment. Hallin suggested that half the live crown, or six-tenths of total height of the tree could be pruned without adverse effects on growth. Pruning out three-fourths of the live crown resulted in death of 52 percent of such treated trees at the end of 5 years. Also of considerable interest was the rapid growth rate found for open-grown trees on the poor site where the study was installed. Practical guides to pruning heights were also given. In general, the 10-year data substantiate Hallin's conclusions.
