Master Gardener program
Cooperative Extension at each state's land-grant university trains residents in horticulture and asks for volunteer hours in return — answering the public's gardening questions, staffing help desks, and working demonstration gardens. The training is publicly funded, though most counties charge a course fee towards materials. Both that fee and the application window are set county by county, so this page tracks what each state's own Extension publishes, and links you to the page that names your county's office.
