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.

Application Details

Who are Master Gardeners?

Master Gardeners are community members from a wide variety of backgrounds. They are passionate about serving their communities and sharing gardening best practices. They have taken the Master Gardener training and share their time and expertise as volunteers in community gardens, city beautification projects, and farmers markets to name only a few areas. They love to share their knowledge and give back to the community as volunteers. Any resident of Linn County is invited to apply to become a Master Gardener.

What happens after the training?

After you complete your training, you'll volunteer in the community at approved Master Gardener projects throughout the county. You'll need to complete 40 hours of volunteering by December 31 of the year following the completion of your training. Projects include working in community gardens with community volunteers, administrative work, answering questions from the public, assisting at our plant sale--there are many different opportunities available.

Thereafter, you'll remain active by attending ten or more hours of continuing education and contributing 20 hours or more of volunteer community service.

Not interested in volunteering?

Register for the core course as a Pro-Hort trainee ($550 fee) and receive a certificate upon completion of the course.

If you have any questions, call the Extension Office at 515.993.4281.
