Performed a detailed crown cleaning on an established Robinia pseudoacacia (Black Locust), addressing significant structural concerns related to multiple co-dominant leaders with included bark throughout the canopy. These included unions create high-risk zones for torsional stress and potential limb failure, particularly under increased seasonal loads. Selective pruning focused on reducing mass and end-weight over the neighboring structure, especially above the garage, where lateral growth posed a hazard due to its leverage and attachment points.
Reduction cuts were carefully made to appropriate lateral branches in accordance with ANSI A300 standards, preserving branch collar integrity to promote proper wound compartmentalization. Additional dead, declining, and poorly attached limbs were removed to enhance airflow, light penetration, and mitigate wind sail. This crown management prepares the tree for winter snow accumulation and wind events, reducing structural stress while maintaining canopy symmetry and long-term vigor.
