Who are University of California Master Gardeners?

University of California Master Gardeners are trained volunteers from all walks of life who share objective research-based knowledge on all aspects of home horticulture with county residents after receiving 50 hours of training from University of California academics and external practitioners. Master Gardeners share this knowledge primarily by conducting workshops and demonstrations; disseminating gardening literature at public service events; addressing inquiries received through garden phone and email hotlines; identifying pest problems at plant clinics; and, contributing to our UC blogs and newsletter.

The main priorities of the San Bernardino County Master Gardener program are:

- Sustainable Landscapes that conserve water, recycle greenwaste, nurture soil, use integrated pest management principles stressing prevention to ward off pests and weeds, are energy-efficient, and attract appropriate wildlife.  

- Food Production (backyard, community, and school gardens grown pesticide-free)

- Healthy Communities that connect our growing urban population with natural environments that promote physical, mental, and emotional well-being.

Master Gardeners also provide information in other areas of home horticulture and community greening. If, for example, you are an expert in a specialty area such as bromeliads, low impact lawns, plant propagation, or any other area, do not hesitate to apply to the program and expand our palette of community education based on your special skills!
