UC Master Gardeners are University of California Cooperative Extension (UCCE) trained volunteers. They are residents of our community who give back all year to provide UCCE researched-based horticultural information to people in their communities and throughout the state. They give talks and demonstrations, conduct plant clinics, staff phone help lines, provide training at community gardens, support school garden programs, staff information tables at Farmers Markets, fairs and nurseries, and more.
