Have you ever asked yourself – “what is wrong with that plant?”  This three-hour hands-on workshop will walk you through the diagnostic process using an extensive number of samples, case studies, and the 23 Questions of Plant Diagnostics. The workshop is modeled after programs given throughout the U.S. and Canada at conferences and to tree care, nursery, and landscape companies.


Plant problem diagnostics is key to good tree health care management and a precursor to proper and effective arboricultural treatments. Environmental, cultural, pest, disease, chemical injury and other problems will be addressed throughout the program. The workshop will be presented as a team approach allowing for interaction in smaller groups with samples and case studies, followed by a catharse of the larger class and sharing of small group diagnostic discussions.


Sharpen your plant scene investigation (PCI) skills and strengthen your ability to determine what is wrong with that plant.
