Master Gardener Onboarding

Registration for 2023 is now open!

Course dates: January 17 – March 31, 2023.
Registration deadline: March 1, 2023.

Wisconsin Extension Master Gardener Onboarding is an online course for individuals wishing to become Wisconsin Extension Master Gardeners. Joining the program is a two-step process.   Step #1 is participating in an approved learning opportunity from the Wisconsin Extension Horticulture Program.  Step #2 is registering and completing this course. 

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 a 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.

This course:

  • Serves as an orientation to the Wisconsin Extension Master Gardener Program and covers its requirements.
  • Provides a horticulture exam for you to demonstrate a baseline of horticultural knowledge. 
  • Sets up accounts to access computer platforms used in the program.

The Onboarding course does NOT provide training in horticulture content (Step #1). We require completion of the Foundations in Horticulture course or another approved learning opportunity from the Wisconsin Extension Horticulture Program.
