Master Gardener Program

The Master Gardener Program trains garden enthusiasts to learn, grow, and teach others about plants and gardening in the home landscape. Participants receive 40 hours of training via webcasting, face-to-face, and hands-on workshops, while interacting with others of similar interests. After completing their training, Master Gardener Interns volunteer 40 hours of service in county approved projects related to gardening education to become active Master Gardeners. To maintain active status, Master Gardeners must attend at least 10 hours of county approved continuing education and volunteer at least 20 hours of service on county approved projects.
