Steps to becoming an Extension Master Gardener

  • Once you receive notice that your background check has cleared, you can register for the core course.
    • The course fee is $295, with an optional $25 for a printed copy of the manual.
    • Fee includes the background check and course.
    • Registration is due by December 1.

  • 48+ hours of basic horticulture education are offered annually.
  • The course is entirely online for 2022. It begins in January and is self-paced through mid-May.
  • Taught by University of Minnesota Extension educators and faculty.
  • Attend bonus weekly online webinars with experts! Sessions are recorded to watch later.

  • All students must complete online quizzes for certification. An active email address and reliable internet access are required.

3. Share your knowledge

  • During your first year, volunteer 50 hours on projects and events that deliver horticulture education and information to the public.
  • 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 in your community.
