Become an Iowa Master Gardener

If you have an interest in gardening and would like to volunteer in your community, consider joining the Iowa Master Gardener program. Whether you are a long-term veteran of gardening or a novice, you are welcome to join.

The program provides selected volunteers training on many aspects of gardening. In exchange for training, Master Gardeners share their time and knowledge in approved projects within their local communities. Training consists of 40 hours of Web-based broadcasts and face-to-face instruction at extension offices and on the Iowa State University campus. After training, participants must complete a one-year Master Gardener internship consisting of 40 hours of approved volunteer service projects. In subsequent years to maintain active Master Gardener status an additional 12 hours of volunteer service and 6 hours of educational updates are required annually. More
