UC Master Gardeners of San Luis Obispo County

Welcome!

The UC Master Gardener Program is a volunteer-driven public service that provides research-based gardening and pest management information to California residents. Through workshops, community outreach, and educational resources, we help home gardeners make informed decisions about sustainable gardening, water conservation, and landscape management.

We offer free advice, hands-on demonstrations, and science-based information tailored to local growing conditions. Whether you're looking to attend a workshop, ask a gardening question, or volunteer, we're here to help.
