The University of California (UC) Master Gardener Program extends to the public,  UC research-based information about home horticulture and pest management. In exchange for the training and materials received from UC, master gardeners perform volunteer services in a myriad of venues.

The Master Gardener Program is an example of an effective partnership between the University and motivated citizens. Because certified master gardeners represent UC Cooperative Extension (UCCE), they broaden UCCE's client base and sphere of influence.

The Master Gardener Program is administered locally by participating UCCE county offices, the principal outreach and public service arm of the University's Division of Agriculture and Natural Resources.
