Our History

For more than 100 years UC Cooperative Extension advisors and specialists have worked with communities across the state to address economic, agricultural, natural resource, youth development, and nutrition issues. For 40 years of UC Cooperative Extension's history, UC Master Gardener volunteers have shared research-based home horticulture information with the public. The first UC Master Gardener Programs started in 1980, with graduating classes in Sacramento and Riverside counties. Since these humble beginnings programs are now thriving in more than 52 counties across the state.
