Plant Health Advising

If you like to share your knowledge of plant culture and health, you can use this talent to assist others as a UW-Extension Plant Health Advisor. PHAs are Master Gardeners who help horticulture staff at county Extension offices to meet the diagnostic needs of the gardening public by responding to inquiries:

  • By phone
  • Though samples submitted
  • In person at the office
  • At outreach sites

They also assist with preparation of educational displays and exhibits related to plant health issues.
