“ Pruning is done very late, when the young shoots are already some centimeters long. The sap used up in the growth of the shoots cut off by the pruning shears is a great loss to the tree, which, being no longer able to supply ample nourishment to the lower buds of the branches, turns them into flower-buds. ”
