The Master Gardener volunteers organize to extend educational services to their communities. The four critical areas are: Healthier Plants, Healthier Environment, Healthier Gardeners, and Healthier Community.
Our Mission: To extend research-based knowledge and information on home horticulture, pest management, and sustainable landscaping practices to the residents of California.
