This full-day seminar brings together three of the industry’s most respected leaders to explore the science, strategy, and skilled practice of structural pruning. Designed for arborists, urban foresters, landscape professionals, and anyone committed to long-term tree health, the program blends foundational theory with advanced techniques and hands-on fieldwork.

There will be ample time to revisit the trees pruned in previous years, assess their development, and discuss their responses together as a group. We’ll be returning to the same park and the same trees examined in 2023, giving participants a unique opportunity to observe their ongoing progress and structural changes over time.
