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.

The Master Gardener program is a volunteer service training program whereby adults are given advanced training in horticulture in exchange for volunteer service to the community.


The mission of the Master Gardener Program is to provide current, research-based, home horticulture information and education to the citizens of Iowa through ISU Extension programs and projects.  Through their participation in educational activities, Master Gardeners also increase their own personal knowledge in horticulture.
