Master Gardener Program

About the Delaware County Master Gardeners!

The Master Gardener program is a volunteer service program where 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 residents of Iowa through ISU Extension programs and projects. Through their participation in educational activities, Master Gardeners also increase their own personal knowledge in horticulture.

In September of 1994, the first local Master Gardener classes were held in Delaware County.  Five individuals had taken training outside of the county prior to this time and decided to get a program started in our county.  The group has grown over the past nearly 30 years to include more than 35 active Master Gardeners in Delaware County! 

The Delaware County Master Gardener typically meet the third Tuesday of each month!  Learn more about service projects and events below!

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.
