Arboriculture & Urban Forestry 36(1): January 2010 growth reductions. The desired branch:stem ratio of less than 0.33 for safe removal of branches stated in Danish pruning rec- ommendations, however, was not achieved by any treatment. In light of the presented results, this recommendation should be re- considered and possibly related to specific tree age or species. LITERATURE CITED Anella, L., T.C. Hennessey, and E.M.
