Tree Pruning with Purpose with Dr. Jason Gordon

Comprehensive Guide to Tree Pruning with Dr. Jason Gordon | Getting the Best of Pest Green Series --- Join Dr. Jason Gordon, Assistant Professor of Community Forestry at the University of Georgia, in the first Getting the Best of Pest Green Series webinar of 2022. Dr. Gordon provides an in-depth overview of tree pruning techniques, types, and systems, focusing on safety standards (ANSI A300 & Z133) and the biology of trees. He discusses proper pruning methods, the importance of knowing tree biology, the timing of pruning activities, and specific objectives such as mitigating storm damage, improving tree structure, and enhancing aesthetics. The session includes practical advice on avoiding improper techniques like topping and highlights the concept of natural pruning to achieve healthier and safer trees. --- 00:00 Introduction and Speaker Introduction 00:39 Technical Difficulties and Presentation Setup 01:23 Overview of Tree Pruning 02:28 Pruning Standards and Safety 03:24 Biology of Trees and Pruning Basics 08:21 Compartmentalization and Pruning Effects 12:57 Pruning Objectives and Considerations 20:22 Pruning Systems and Techniques 27:53 Finishing the Three-Cut Method 28:27 Avoiding Peeling and Defensive Zones 29:09 Types of Pruning Cuts 30:33 Best Practices for Large Branches 30:58 Introduction to Pruning Types 31:14 Crown Cleaning and Thinning 32:57 Crown Raising and Reduction 36:50 Structural Pruning Techniques 41:34 Timing and Benefits of Pruning 43:01 Key Takeaways and Final Thoughts 46:00 Q&A Session --- Dr. Jason Gordon, a community forestry expert, provided an in-depth webinar on tree pruning, highlighting the importance of adhering to established standards (ANSI A300 and Z133) to ensure tree health and safety. He explained that trees are modular and autonomous, making it critical to understand their biology when pruning. Proper pruning involves making cuts at the node rather than the internode to preserve the tree’s natural ability to compartmentalize and seal wounds. Gordon emphasized the need for clear pruning objectives, whether for hazard mitigation, structural improvement, or aesthetics. He also covered various pruning systems, including natural pruning, pollarding, and crown reduction, and explained that the chosen method should align with the tree’s species and growth patterns. Understanding which species are good compartmentalizers, such as certain maples, is essential for effective pruning. Finally, Gordon recommended pruning during the dormant season to reduce pest risks and allow the tree to heal effectively. This approach, coupled with a thorough understanding of tree biology and species-specific responses, ensures that pruning enhances the tree’s health, structure, and longevity.
