OSU Extension serves home gardeners by answering their gardening questions, teaching at garden club programs, and by offering the internationally known Master Gardener Program. Our goal is to enhance positive experiences of home gardeners. Below are resources where you are able to submit your general questions and diagnostic requests.
Master Gardener Volunteer Program
Our Master Gardener Program was started in 1992. The Master Gardener training course consists of a minimum of 50 hours of instruction. An equivalent number (50) of horticultural significant volunteer hours within 1 year following the initial instruction is required to become a certified Master Gardener. We have trained over 1,000 Master Gardeners. Our Master Gardener volunteers have been involved in a wide range of horticulture endeavors, from providing educational outreach programs at the Krohn Conservatory, to evaluating new plants at the Cincinnati Zoo and Botanical Gardens as well as numerous other projects.
