What is the Master Gardener Volunteer Program?

The OSU Extension Master Gardener Volunteer Program is a premier, statewide network of volunteer education and leadership development; as well as a consumer horticulture education delivery system that maximizes human, material and natural resources, and values teamwork and excellence in educational programming. The Master Gardener Volunteers' knowledge, experience and enthusiasm have become essential to Extension education of consumer horticulture in the state of Ohio.

The Master Gardener Volunteer Program provides an extensive course in horticulture in exchange for a donation of volunteer hours to share your gardening knowledge with the community through OSU Extension sponsored activities.

Master Gardener Volunteer Training

Volunteers are an important component of the OSU Extension system. Volunteers are not required to have gardening skills or knowledge; but a passion for learning about gardening and sharing this knowledge with others is a must! There are many opportunities to obtain hours either with a “hands-in-the-dirt” group project or as a “behind-the-scenes” individual contributor supporting non-physical activities.

Master Gardener Volunteer online training is offered for residents of Licking County and surrounding areas. The online training program provides a balanced, integrated, practical course in plant science. Core topics that are part of the training are oriented to Extension and the Master Gardener Volunteer Program:

    Basic Botany
    Plant Physiology
    Soils and Soil Fertility
    Basic Entomology
    Basic Plant Pathology
    Plant Disease Diagnosis
    Pesticide Use and Safety
    Plant Identification
    Home Lawn Care
    Trees and Shrubs
    Home Vegetable Production
    Home Fruit Production
    Backyard Wildlife Management
    Herbs and more!
