This study was established on which germanium (Ge), known as one of the functional nutrients, treatment is the most effective method for increasing Ge uptake and contributing flowering development in the pruned branches in the winter. Ge treatment included foliar application, soil fertigation, trunk injection, and the three-combined application. Ge concentration in the pruned branches was greater on the three-combined treated trees, and Ge treated branches had greater Ge concentrations than the control. Pruned branches grown in the solution culture had greater bud weight and bud scale number on the Ge treated trees than the control. Ge treatments increased flowering per branch and flower number per bud as well as improved resistance of the freezing temperature damage. Overall, there were no consistent results of all the variables by the Ge application methods.
