As you begin your time with the Wisconsin Extension Master Gardener Program, we want to start off by saying “Thank you!” for choosing to give your time and talents in volunteer service. As an Wisconsin Extension Master Gardener, you will become an important resource in your community as you help others make good gardening decisions based on university research.

Individuals wishing to become a Wisconsin Extension Master Gardener must complete our Master Gardener Program Onboarding course. This course achieves three important steps in becoming an Extension Master Gardener in Wisconsin:

  • Serves as an orientation to UW-Madison Division of Extension and reviews the scope of being a participant in the Wisconsin Extension Master Gardener Program.
  • Provides the horticulture exam for you to demonstrate a baseline of horticultural knowledge.
  • Creates an account in the Wisconsin Extension Master Gardener Program online reporting system.

The Onboarding course does NOT provide training in horticulture content. We require completion of the Foundations in Horticulture course or another approved learning opportunity from the Wisconsin Extension Horticulture Program.

Registration for the onboarding course opens in December. The course is online and asynchronous. You can complete all aspects of the course at your own pace within the course dates. It begins in January. The deadline to register for the course is March 15. You must complete the course by March 31. No refunds are available after you register or if not completed by the deadline.

Getting Your Username and Logging In

After registering for the Onboarding Course you will get a NetID from UW-Madison.  Please see the instructional videos, below, to activate your NetID.  If you completed Foundations in Horticulture, you will continue to use that assigned NetID.
