UC Master Gardeners of Mendocino County

UC Master Gardeners of Mendocino County University of California Master Gardener volunteers are locally trained garden mentors who will answer your questions using UC research-based information.

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. In Mendocino County, there are two groups of Master Gardeners due to the very different climates between the coastal region and the inland region. Typically there is a class given each year. Classes are held at two different locations, one is on the coast at the Mendocino Coast Botanical Garden the other is at the UC Cooperative Extension office in Ukiah. The class alternates between coast and inland each year. Master Gardeners from both programs participate in continuing education to broaden their resource and knowledge base. For the Master Gardeners' office in Ukiah, phone 707-463-4994 or email [email protected]. For the Master Gardeners' office on the coast, call:
