The Master Gardeners are volunteers that are trained and certified by the University of California to promote and extend research-based, scientifically accurate horticultural information to the residential gardening public.

Our Guiding Principles are to support regional biodiversity, conservation of resources, and the minimizing of pollution and waste. We focus on climate and soil adapted plants for the Sierra foothills, utilizing a ‘zone’ process to teach sustainable landscape techniques that match the needs and conditions in the design of a particular landscape.

The Nevada County Master Gardeners offer a variety of platforms to inform the public, including free community workshops (see our schedule below), a weekly radio call-in show, information booths at local events, and a speakers’ bureau. We have an office in the Grass Valley Veterans Building, open on Tuesdays and Thursdays from 10 am to12 pm (530) 273-4563. We also maintain a “Hotline” for after-hours phone questions at (530) 273-0919.

Visit our Demonstration Garden that is designed as a teaching tool to display a Mediterranean Garden that is suitable to our Western Nevada County foothill climate. Located at 1036 W. Main St, Grass Valley, on the grounds of the Nevada Irrigation District Business Center, the ‘Demo’ Garden exhibits a wide variety of garden techniques, water conservation and a diversity of plant venues, including, but not limited to:

· an Orchard

· an Edibles Garden

· a Raised bed/container garden area for vegetables & herbs

· a Children’s Garden

· an Oak Habitat and native grass Meadow

· a Mediterranean Garden

· an active Compost program

· a hoop House under construction to facilitate our propagation program
