What is a Master Gardener, and what makes one such a unique resource? We’re glad you asked!

Master Gardeners complete a Master Gardener program through colleges and universities throughout the United States. These programs provide intensive home horticulture training to local garden enthusiasts, teaching them area-specific gardening techniques that are then taught throughout the local communities. Master Gardeners volunteer their time and knowledge by giving lectures, creating gardens, conducting research, and starting horticulture projects within their local communities.


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


The UC Master Gardeners program is a public service offered through the University of California’s Division of Agriculture and Natural Resources.
