How to Become a Master Gardener

Are you interested in learning more about local gardening? Would you like to share your knowledge with other gardeners? If so, consider joining the Inyo-Mono Master Gardeners!

Master Gardeners are volunteers trained by the University of California whose mission is to help others garden successfully. Applicants receive training in Horticulture and are expected to serve 50 hours of volunteer service answering home gardening questions and working in our projects.

Since 2019 we've been conducting classes using a hybrid online/in-person model to make the course more accessible to working members of the community, and to keep costs as low as possible.

Our next training class will be in 2023.


Class Information

There was an informational session scheduled for January 18, 2023 via Zoom. Applications were due February 19. 

The 2023 class is a hybrid online/in-person training. The first few weeks of the class will be a combination of online content and Zoom instruction with online drop-in hours available. An test of garden knowledge from this section will follow.

Since some aspects of gardening education don't translate well into the virtual realm, after the remote-learning portion, we will have 2 weekends of in-person, mostly hands-on sessions in May. The final portion of the training will be a project that will let you practice what you have learned. 

Graduation is scheduled for June 14, 2023.

The proposed calendar for the training is available in this file: 2023 Master Gardener Training Calendar (Subject to change, but it should be fairly accurate.)

In order to participate you will need access to the internet with enough bandwidth to watch videos or use Zoom. Smartphones/mobile devices will work fine. We will also be using Trello to organize the course, which has a free smartphone app. 

There will be a $110 fee to cover materials costs.

If you have questions about the 2023 Master Gardener Basic Training please address them to our helpline at immg@ucanr.edu. The best way to find out more about the class is to join our e-mail list below if you haven't yet.


Please note, this training is for residents of Inyo or Mono counties. Other counties have their own training program and schedule. See this map for their contact information.
