Our certified arborists evaluate the tree, propose a plan, and make ANSI A300 cuts at the branch collar to encourage healthy wound-sealing (CODIT). ## Common Pruning Types - **Crown thinning** — reduces wind load and lets more light through the canopy - **Crown raising** — lifts lower branches for clearance over walkways, driveways, or roofs - **Deadwooding** — removes dead branches that pose hazards or invite pests - **Structural pruning** — corrects co-dominant leaders and weak unions on younger trees - **Storm-prep pruning** — targeted work before severe weather to reduce failure risk ## Timing for Westchester Species Late dormant season (late winter) works for most Westchester species. Oaks are best pruned in dormant months to reduce oak wilt risk. Coastal trees benefit from a targeted storm-prep pruning [/guide/storm-prep-pruning/ →](/guide/storm-prep-pruning/) window in late summer. ## Coverage We prune across Westchester County [/service-areas/ →](/service-areas/) , from mature specimen trees in Bronxville [/service-areas/bronxville/ →](/service-areas/bronxville/) to coastal-exposed canopies in Larchmont [/service-areas/larchmont/ →](/service-areas/larchmont/) and Rye [/service-areas/rye/ →](/service-areas/rye/) .

Younger trees benefit from more frequent structural pruning. ### What's the difference between trimming and pruning? + Trimming focuses on shape and appearance; pruning targets tree health and safety by removing deadwood and problem branches per ANSI A300 standards. ### Can over-pruning hurt a tree? + Yes. Removing too much foliage stresses a tree. We follow ANSI A300 limits — usually no more than 25% of live foliage in a single visit. ### When should I book storm-prep pruning? + Before hurricane and nor'easter season — late summer to early fall in Westchester is common. ### How often should mature trees be pruned? + Most mature shade trees benefit from professional pruning every 3 to 5 years, while young trees may need structural pruning more often. Storm-exposed trees often warrant a pruning check before severe-weather season. Learn More ## Tree Trimming & Pruning Guides Guide ### How Often Should Trees Be Professionally Pruned?
