UW Extension Plant Diagnostic Class

UW-Madison’s Extension Horticulture Program is offering an online non-credit certificate course called “Plant Diagnostics: The Step-by-Step Approach to Identifying Plant Problems.” The class runs from Feb. 1 to April 30, 2023.

As a student, you will move at your own pace through 13 modules with online videos, reading and interactive exercises. You will learn the steps of the plant diagnostic process in an easy-to-understand way. You will become familiar with appropriate unbiased, research-based resources to use in the diagnostic process.

After completing the course, you will be empowered to use the process to figure out tree and landscape problems. The course also has two live webinars, “Putting the Process into Practice: Real World Diagnostics,” led by Extension educators who practice plant diagnostics, and “Meet the Labs!” presented by UW-Madison diagnostic lab directors.

All content is applicable to arborists and people managing urban forests, with frequent examples relating directly to trees and shrubs and some examples coming from other domains of horticulture. ISA Certified Arborists who complete all the modules before April 30, 2023 will awarded 7.5 CEUs.
