Summer Pruning Peach Trees

Without any fruit to slow down shoot growth, our peach trees have put out too much growth. Excessive shading of the lower shoots leads to their death in winter and subsequent low yield in the lower canopy. It will not reduce vigor of the tree, but will keep the lower canopy from becoming productive. It may delay the onset of winter hardiness in fall, so try to complete it by mid August. Here is a link to an article on Rich Marini’s experience with summer pruning: Correct summer pruning techniques for peach trees stressed – Fruit Growers News. The simplest summer pruning method involves removing the most vigorous shoots from the inside and upper canopy.
