How to Become a Master Gardener

Are you interested in learning more about local gardening from experts? Would you like to share your knowledge with other gardeners? If so, you may enjoy joining the Inyo - Mono Master Gardener Program.

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

We've closed applications for the 2021 training class. We offer MG training classes in odd-numbered years, so look for our next class in 2023. 

If you have questions about joining our program please contact us. You can sign up below to get on our mailing list.
