Master Gardener Program

Master Gardener Program in Cass County


Master Gardener Logo

Cass County has a large group of active Master Gardeners that meet monthly to plan projects such as community garden spaces, food donation projects, educational activities, grants and scholarships. The goal of the Master Gardener program is to support horticulture education and community service.  Cass County Master Gardeners provide many hours of volunteer service and gardening education within their local communities. To raise funds for these activities, the group annually holds a spring and plant sale fundraiser. 

Cass County hosts a local training for new Master Gardener volunteers approximately once every other year. In addition to this training, the group holds a variety of events that are open to the general public throughout the year.  For more information about Master Gardener activities in Cass County, please call the Cass County Extension Office at 712-243-1132, or email Cass County Extension Director and Master Gardener Coordinator Kate Olson at  In addition, you are invited to follow the Cass County Master Gardeners at their Facebook page at to keep up with local events and tips for gardening.

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.
