Gardening with the UC Master Gardener Program

Who Are Master Gardeners and What Do They Do?
Master Gardeners are volunteers from the community who are trained by the University of California Cooperative Extension specialists and other qualified instructors using research-based information to promote environmentally responsible and sustainable horticultural practices in the home, community and school landscapes.

Master Gardeners extend research-based information by conducting workshops and demonstrations, diagnosing plant and pest problems, speaking to community groups, educating teachers and parents at school gardens, and answering gardening questions at fairs and farmers markets as well as our email and phone helplines.

By training Master Gardener volunteers, we empower neighborhoods to create their own solutions and foster healthier gardens, communities and a sustainable environment.
