The Tennessee Extension Master Gardener Program is a volunteer program that serves state citizens with horticulture education! This program trains and certifies volunteers who provide community service through county Extension offices. Master Gardeners are trained, certified volunteers for the University of Tennessee Extension County Offices.

Once certified, Master Gardeners are invited and encouraged to join the Master Gardeners of Hamilton County to maintain their certification and become part of a strong community organization with a commitment to public service.

Certified Master Gardener volunteers assist UT Extension staff by sharing research-based information with the general public. They also offer many educational programs throughout the community and provide countless hours of volunteer service.
