Proper Pruning = Proper healing
Making cuts at the correct angles avoids damage to the vascular tissue of the tree, enabling the tree to form 'reaction wood' (callus wood) - proper sealing of pruning wounds is critical for the tree to compartmentalize and seal itself from insects and disease.
Progression of reaction wood growth from pruning cut to full sealing of pruning wound.
