By the numbers

UC Master Gardener volunteers are passionate about extending their knowledge of sustainable gardening practices and building partnerships for sustainable community gardens and green spaces. Their tireless efforts are reflected in the impressive data and numbers presented in this impact report. From the number of volunteer hours logged to the pounds of produce grown and donated to local food banks, the impact of the UC Master Gardener Program is clear.

"Thank you for all you do to serve our residents, schools, community gardens, hospitals, shelters, the incarcerated, and more. And, for all you’ve given me.”
