Since 1981, the University of California Master Gardener Program has been extending UC research-based information about home horticulture and pest management to the public. The UC Master Gardener Program is a public service and outreach program under the University of California Division of Agriculture and Natural Resources, administered locally by participating UC Cooperative Extension county offices.

The UC Master Gardener Program is an example of an effective partnership between the University of California and passionate volunteers. In exchange for training from the University, UC Master Gardeners offer volunteer services and outreach to the general public in more than 50 California counties. Last year 6,116 active UC Master Gardener volunteers donated 398,265 hours, and 5.4+ million hours have been donated since the program’s inception.
