Master Gardener Program
About the Master Gardener Program
  • It is a volunteer training program conducted by University Extension designed to help county extension centers meet the demands for consumer horticulture information. Master Gardeners take classroom training coordinated by local extension staff with the assistance of state extension specialists located at Oklahoma State University. After classroom training is completed, program participants are involved in an internship program of volunteer service coordinated by local extension centers Volunteer service components vary widely around the state, but in all cases are educational, extension related, and represent the interests of University Extension.
  • Master Gardeners have become a vital part of Extension's ability to provide consumers with up-to-date, research-based information. Master Gardening has also become a popular volunteer activity that gives its participants a sense of community spirit, accomplishment and intellectual stimulation.
