Water-Wise Landscaping Workshops

The City of Napa teams with other local agencies to sponsor Free Water-Wise Landscaping Workshops made possible by the expertise of the UC Master Gardeners, the California Native Plant Society (CNPS) Napa Valley Chapter, the Napa County Resource Conservation District (RCD), and area professionals. Topics are designed for Napa Valley residents interested in maintaining and beautifying their yards while minimizing their water use. The workshops feature expert presenters, free water-saving tools, literature, topical door prizes, and the latest on state and local rebate programs. Water conservation is a way of life in California. Outdoor efficiency remains the key to our water future.
