The role of the Master Gardener

Master Gardeners provide free, research-based horticulture information to Nevadans. They are volunteers who learn advanced plant science skills from at least 50 hours of classroom instruction by University of Nevada Cooperative Extension professionals. After training, Master Gardeners volunteer a minimum of at least 50 hours a year to pass along their newly acquired knowledge through the media, talks and workshops. They answer phone calls, send out informational materials and develop community gardens.

Master Gardeners provide a valuable service to the community by helping Cooperative Extension meet this demand for information. For more information about becoming a Master Gardener in the Carson City and Storey, Douglas and Washoe counties, please contact:
