How to Become a
Knox County Master Gardener

The Extension Master Gardeners of Knox County is an award-winning volunteer organization comprised of gardening enthusiasts who are passionate about horticulture, volunteering, and educating in their community. The main goal of the Knox County Master Gardener Program is to get more people in our local area interested and involved in the love of gardening. We believe that the more people learn to love gardening, the healthier our world will be.

Our True Purpose

To realize our mission, our volunteer team educates the community about home horticulture so that our neighbors have the current knowledge about best practices and methods that are environmentally friendly and sustainable. We also manage a variety of community and demonstration gardens around the county that provide healthy food to people in need.


We believe that when eco-friendly, evidence-based gardening approaches are used, consumers will see better results in their gardens, feel the joy and satisfaction of gardening, and help contribute to a healthier, more sustainable world.


Volunteers Make the Difference!

Over 170 enthusiastic, friendly volunteers throughout Knox County manage all aspects of the program and deliver services to the community. Everyone who is trained to become a certified Master Gardener is expected to return a minimum number of community service hours. Most volunteers contribute much more than expected because we are so passionate about what we do and see real impact as a result of our work. We know you will, too.

Join Our Volunteer Team!

We are currently seeking dedicated volunteers to join us for our next round of annual training.  While gardening experience is always appreciated -- and you will find your tribe of garden fanatics here -- we also welcome beginners on our gardening journey.  

Participation in the class requires a commitment for service to Knox County (and home county, if not a resident of Knox County).
