Subordinate Lateral Pruning
Perhaps your tree is in good health but will require extensive pruning to meet the standard clearance requirements. Depending on the branching structure of the tree and the tree’s proximity to electric lines, KUB may use subordinate pruning as a temporary measure to remove a branch over more than one pruning cycle rather than all at once. Subordinate pruning is consistent with industry best pruning practices.
This is more often an option for trees that have not been pruned before, rather than trees with regrowth from a previous pruning. KUB crews will make proper lateral pruning cuts to achieve standard clearance in three to four years during the next pruning cycle scheduled in your area, or sooner if the tree’s branches grow to endanger electric lines again before then.
