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.
Training classes run from February to May each year, with applications due in October of the previous year. To become a certified Master Gardener, you must fill out and submit the application form, attend training classes, pass the final exam and volunteer time to your community. Once certified, you will need to attend advanced training classes and volunteer time on Master Gardener projects each year to maintain certification.

Training consists of seventy hours of classroom instruction taught by Texas A&M educators and specialists. Class topics include Botany/Plant Physiology, Soils, Lawn Care, Water Conservation, Vegetable and Herb Gardening, Insects and Landscape Horticulture. (See 2012 Class Schedule.) Experienced, active Master Gardener mentors are paired with trainees to help guide them through a successful classroom training and volunteer experience. The fee for training is $225 in 2012, which includes the training manual. The fee is payable by check (preferable) or cash on the first class day.
Upon completion of the classroom training and passing the final exam, you will become a Master Gardener Intern. The internship consists of contributing seventy volunteer hours of service toward Master Gardener projects during the intern year. More about our current projects can be found on the Denton County Master Gardener Projects page.
Certified Texas Master Gardeners are those who have completed their classroom training and internship. A certificate of completion is presented to each intern at the Denton County Master Gardener annual award dinner.
Certified Master Gardeners
Each year, Denton County Master Gardeners must earn a minimum of twelve hours of advanced training and volunteer a minimum of twelve hours on any Master Gardener project to maintain active Certified Master Gardener status.
