Become a Master Gardener

Who are Master Gardeners?

Master Gardeners are from all walks of life and volunteer on behalf of their university. They share gardening best practices with people in their communities to promote healthy landscapes, healthy foods and healthy lives. They complete a university-taught core course and contribute a certain number of hours teaching research-based horticulture practices in their communities.

Steps to becoming an Extension Master Gardener

1. Be selected by your county program for a Master Gardener internship

  • Complete and submit the application. Applications are due October 2.
  • Be selected for an interview.
  • Submit and pass a background check (online). (Note: All Master Gardener volunteers must have a recurring background check every three years.)
  • Receive notification that background check has cleared, then register for core course and pay the $320 fee (includes $290 course and materials fee and $30 background check fee). Registration is due December 1.

2. Complete the Extension Master Gardener core course

  • 48 hours home horticulture education, offered annually, January to April.
  • Face-to-face and online options for general content delivery. All students must complete online quizzes for each topic module.
  • Taught by Extension educators and faculty at the U of M Landscape Arboretum.

3. Share your knowledge

  • Volunteer 50 hours on projects and events that deliver horticulture education and information to the public.
  • Volunteer and learn alongside experienced Extension Master Gardener volunteers.
  • Report your volunteer hours online by December 31.
  • Individuals who drop out of the internship before fulfilling the educational and volunteering requirements will be required to pay an additional $300.

4. Celebrate!

When your internship is completed, you'll start the next calendar year as an active University of Minnesota Extension Master Gardener.

5. Stay involved

To maintain your active Extension Master Gardener volunteer status, you will complete at least 25 hours of volunteering and the required continuing education hours per year. Continuing education hours vary from five to 12 hours depending on county.
