UC Internet Resources

The UC Master Gardener Program is designed share science-based information with the public.  In addition to our many Volunteers, the following resources provide the answers to many, if not most, of your questions.

California Garden Web

The UC Master Gardener Program designed the California Garden Web to serve as a portal to organize and extend the University of California's vast collection of research-based information about gardening to the public. The California Garden Web focuses on sustainable gardening practices.

Integrated Pest Management Program

Integrated pest management, or IPM, is a process you can use to solve pest problems while minimizing risks to people and the environment. IPM can be used to manage all kinds of pests anywhere–in urban, agricultural, and wildland or natural areas.

California Backyard Orchard

When a home orchard is based on an understanding that it is, in fact, a living expression of genetics interacting with soils, weather, tree spacing, pests, and many other factors, then the outcome will likely be one of success.
