Who Are the Master Gardeners?

Master Gardeners are volunteers trained by Texas A&M AgriLife Extension in research-based horticulture including soils, 2024 conservation, composting, entomology, plant pathology and related subjects.  As Williamson County Extension Service volunteers, they give to the community by extending research-based knowledge and providing solutions in one-to-one problem solving, in demonstration gardens, educational programs, and educational materials.

Individuals make application to enter the training.  Once accepted into the program, trainees begin a one-year process that begins with a minimum of 50 hours of specialized classroom instruction. Master Gardener interns finish requirements by contributing a minimum of 50 service hours and 15 continuing education hours by year’s end to be then certified as a Master Gardener.

The certification and title are good for one year.  To retain certification in Williamson County, Master Gardeners annually contribute a minimum of 40 service hours and acquire 12 hours of continuing education.
