The Nebraska Master Gardener program is a horticulture related volunteer training program based in many counties throughout the state. It has been part of UNL Extension since 1976. Master Gardener volunteers are trained by UNL Extension faculty and staff. They contribute time as volunteers working through their local Extension office to provide horticulture-related information to their community. More specifically, they provide education about sustainable horticultural practices. Participants are required to complete 40 hours of training and 40 hours of volunteer service during the initial year of their involvement in the program. Master Gardener volunteers retain their certification through annual training and volunteering.
