In this episode of Talking Trees, we discuss the first European Tree Worker (ETW) exam held in Hong Kong, which highlighted significant gaps in local training and skills. The exam, covering both practical and theoretical modules such as tree identification, pruning, and Visual Tree Assessment (VTA), revealed that Hong Kong arborists fall short of international standards. Sammy Au, the author of the report, emphasizes the need for improved education and preparation to help local arborists compete globally and enhance the quality of tree care. The episode concludes with an announcement of upcoming exams and a call for arborists to participate and raise their professional level.

In this episode of Talking Trees, we explore the quality requirements for trees intended for planting. We detail different types of trees—bare-rooted, balled, and container-grown—and their specific standards regarding root systems, trunks, and crowns. The episode discusses technical norms, quality assessment criteria, defect tolerance, and inspection procedures. Emphasis is placed on the importance of selecting trees adapted to site conditions, with recommendations to choose smaller trees for easier adaptation and reduced maintenance needs. The discussion is supported by tables of ball dimensions and weights relative to tree size and illustrative visuals.
