2026 Master Gardener Training Program

The UC Master Gardener Program trains volunteers to share research-based gardening knowledge with the public. This course is how you become a certified Master Gardener in San Luis Obispo County. It’s not just a series of workshops — it’s an application-based program with tuition, weekly classes, and a volunteer service commitment.

Not everyone who applies will be accepted. Applicants must attend training, pass a final exam, and commit to at least 50 hours of volunteer service in the first year. Space is limited.
