New Master Gardener Volunteer Deadline

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.
