Pruning Fundamentals    (View PDF)

Richard W. Harris

Abstract: To more effectively prune trees certain aspects of plant growth are presented as well as the more commonly known responses to pruning. Trees with strong apical dominance have few or no laterals on current growth, but their terminals are not able to control growth of lateral buds and shoots in subsequent years. Such trees develop a roundheaded (decurrent) form. The opposite is true of plants having weak apical dominance. They have strong apical control leading to a central-leader (excurrent) form.
