Conifers are a cornerstone of many landscapes, yet a wide range of diseases and environmental stresses can cause needle discoloration, branch dieback, and decline. This webinar will explore common conifer diseases and abiotic disorders, with an emphasis on recognizing the key signs and symptoms needed for accurate diagnosis. Participants will learn how to distinguish disease issues from environmental and cultural stresses, apply practical diagnostic techniques, and implement science-based, Integrated Pest Management (IPM) strategies to support healthy, resilient trees in landscapes and gardens.
