Become a Master Gardener

The mission of the Denton County Master Gardener Association is to educate Denton County residents about safe, effective and sustainable horticultural practices that promote development of healthy gardens, landscapes and communities.  If you love gardening and would like to share your knowledge with others, the Denton County Master Gardener Association offers the opportunity to learn and to serve the community.

Who are Master Gardeners?

Master Gardeners are from all walks of life and volunteer on behalf of their state’s land grant university. What really sets Master Gardeners apart from other home gardeners is their special training in horticulture. In exchange for their training, persons who become Texas Master Gardeners contribute time as volunteers, working through their county’s Texas A&M AgriLife Extension office to provide horticultural-related information to their communities. Texas Master Gardeners are representatives of Texas A&M AgriLife Extension. In all volunteer work related to the program, Master Gardeners follow the research-based recommendations of Texas A&M AgriLife Extension.  The title “Texas Master Gardener” can be used by volunteers only when engaged in Extension-sponsored activities.

How to Become a Texas Master Gardener

Training Classes
If accepted into the Denton County Master Gardener program, you will be required to attend a minimum of 70 hours in specialized training that begins in January and ends in May. Training classes are held each Tuesday from 9:00 AM to 4:00 PM. (See the 2017 class schedule.  Schedule changes may occur due to the weather or instructor availability.)  Our training program offers instruction in Earth-Kind garden management, Integrated Pest Management, soil management, lawn care, ornamental trees and shrubs, plant nutrition, vegetable gardening, home fruit production, perennial and annual flowers, and water conservation. Classes are held at the Global Spheres Center in Corinth.  The address is 7801 S. Stemmons Freeway (IH35E), Corinth TX 76210.


Experienced, active Master Gardener mentors are paired with trainees to help guide them through a successful classroom training and volunteer experience.

The new Class of 2017 begins Tuesday, January 31, and continues through May 2, 2017.   The tuition for training for the Class of 2017 is $240, which covers the manual, class t-shirt, badge, field trips, instructor fees, and graduation dinner costs.  Tuition is due by January 1, 2017, but only after you receive a letter of acceptance.

Volunteer Committment
In exchange for Master Gardener training, first year Denton County Master Gardener Interns are required to volunteer a minimum of 70 hours to projects provided by Denton County Master Gardener Association. A wide variety of projects are available that include becoming involved with youth at area schools, assisting in gardens at senior centers, working on the Denton County Master Gardener Help Line, speaking to large and small groups interested in gardening knowledge, or any one of our major community events we host each year. There are plenty of projects to choose from and all are filled with great people invested in learning and sharing their gardening knowledge! More about our current projects can be found on the Denton County Master Gardener Projects page.

Participants become certified Texas Master Gardeners after they have completed the first year of required training and volunteer commitment. A graduation dinner and awards ceremony is hosted each January to commemorate and award each successful Master Gardener Intern. Texas Master Gardeners in Denton County maintain their certification by attending 12 hours of advanced training and providing a minimum of 12 hours volunteer time each year after their initial training year.
