The Landscape Architect in the Nursery: Tagging Trees and Enforcing Specifications

Tree defects such as co-dominant leaders, girding roots and buried trunk flares, present at time of planting, cause failures and decline long after the warrantee period has expired. Landscape architects may go to nurseries to tag trees; but often inspect only aesthetic qualities, while their planting specifications rely on ANSI Z60.1 for technical standards. But the ANSI standard is guidance for industry definitions and measurements with few conditions about tree quality. This webinar presented by James Urban, FASLA and Paul Josey, ASLA, will guide landscape architects and arborist inspecting the technical quality of B&B and container trees; and discuss common problems and solutions above and below the ground line. The webinar will introduce an evidence-based specifications that set technical standards that support inspections.
