New Master Gardener Volunteer Training

The Master Gardener Program provides intensive training in horticulture to interested gardeners who then volunteer their time assisting with educational programs and activities for Ohio residents through their local Ohio State University Extension county office.

What is the Master Gardener Program?       

Working with county Extension personnel, Master Gardeners provide such educational services to their communities as: answering gardening questions from the public; conducting plant clinics; gardening activities with children, senior citizens or disabled persons; beautifying the community; developing community or demonstration gardens; and other horticulture activities.

How do I know if I’d make a good Master Gardener?

You could qualify to become a Master Gardener, if:                                      

  • You want to learn more about plants and gardening.
  • You are eager to participate in a practical and intensive training program.
  • You enjoy sharing your knowledge with others.
  • You have the time to attend training and serve your community as a volunteer educator.

How do I become a Master Gardener?

To become a Master Gardener, you must:

  • Be accepted into the Master Gardener program by completing the volunteer application. Please note that the class size is limited. Trainees will be selected based upon their application and their availability and willingness to complete their training and volunteer requirements. Applications can also be found here, or picked up at your local extension office. Please email, mail, or drop off your completed application to your local OSU Extension Office no later than May 17, 2023.  More information will be emailed directly to you upon completion of online registration.
