STRUCTURE PRUNNING
STRUCTURE PRUNNING A well trained young tree usually grows into a well structured mature tree. Structure pruning is key! Structure Pruning is the practice of selective trimming to promote a strong framework within the tree which will support future growth. When the tree is around 5 years old, structure pruning should be performed annually on trees that become large at maturity as it encourages a single central trunk and regularly spaced branches that are horizontal. Structure pruning is important for saving maintenance costs in the future. Structural pruning in the landscape aims to develop the strong tree structure we see in the forest. Structural pruning selectively favors a single, dominant leader by suppressing competing leaders using reduction cuts. Reduction cuts shorten stems back to lateral branches at least one-third the diameter of the cut stems. Because future growth is forced into the unpruned leader and growth on pruned branches is suppressed, the ra
