Become a Better Gardener!

UVM Extension Master Gardener Program

The University of Vermont (UVM) Extension Master Gardener program started in 1991 as a unique volunteer program where Vermonters received training by university faculty and industry professionals on research-based gardening information. In return, participants volunteer in their communities by educating others on a number of home horticulture topics.

Our Course

The UVM Extension Master Gardener Course is our 16-week online signature course. It covers the fundamentals of home gardening including basic botany, soil fertility, insects and diseases, vegetable planning and production, herbaceous perennials, small fruit and tree fruit, pollinator plants, tree care, landscape design, and volunteerism. Content is specific to Vermont's growing conditions. The course is offered each winter/spring as required training to become a certified Extension Master Gardener volunteer or as personal/professional development as an at-your-own-pace asynchronous option.

2023 Extension Master Gardener Course

Registration for the 2023 Extension Master Gardener course is now closed (as of January 18, 2023). 

Please read the information below about course details and expectations.

Track 1 (Volunteer Track): Become an Extension Master Gardener!

Track 1 (Extension Master Gardener Volunteer Certification)

The UVM Extension Master Gardener (EMG) Certification program, also known as Track 1, requires an application process and background check for Vermont residents interested in participating. Students who are interested in this track have access to the online course with a weekly schedule that includes real-time Q&A sessions with instructors, quizzes, weekly activities and strict due dates. Students in this track commit to completing all course assignments on time, and go on to a 40-hour volunteer-internship requirement over a 2-year period after the course.

Expectations of Track 1 (Volunteer Track) Students:

  • Commit to completing all course requirements on time (including weekly readings, pre-recorded lectures, quizzes and final exam) and attending all the weekly Zoom sessions on Thursday evenings. We estimate that Track 1 students devote about 6 hours per week to successfully complete the course.
  • Complete volunteerism paperwork during the first week of the course: Volunteer Application, a background check consent form (if you have lived in Vermont for more than a year) or fingerprinting process (if you have lived in Vermont for less than a year); and our Minor Protection Training.
  • Participate in a 40-hour volunteer internship (over 2 years).

Track 2 students have access to all course content but pursue the course at their leisure with a completely optional weekly schedule, assignments and due dates. There is no volunteer requirement and no Extension Master Gardener volunteer certification for Track 2 students. Students who successfully complete the course receive a Home Horticulture Certificate of Completion that may be used for personal or professional advancement purposes.

Expectations of Track 2 (At-Your-Own-Pace) Students:

  • If interested in a Home Horticulture Certificate, complete the course quizzes and final exam before the course closes.

"The UVM Extension Master Gardener Course provided so much information in a way that was fun to learn and easily applicable. I recommend the course for anyone who wants to learn more about gardening, regardless of experience!"

"Having majored in environmental studies and minored in biology, I already had most of the basic knowledge. However, this course allowed me to dive deeper into topics that I am passionate about and provided new knowledge that I know will continue to be useful in my job."
