About the Master Gardener Program

The Master Gardener Program is a volunteer development program offered by the Texas A&M AgriLife Extension Service. It is designed to increase the availability of research based horticultural information and improve the quality of life through horticultural projects.

What’s a Master Gardener?

Master Gardeners are highly trained volunteers working with Texas A&M AgriLife Extension to provide residents with information on environmentally responsible gardening and landscaping. They provide unbiased, research-based information, problemsolving expertise and educational opportunities to residents.

Master Gardeners are members of the local community who take an active interest in their lawns, trees, shrubs, flowers, gardens and environment. They are enthusiastic, willing to learn and to help others, and able to communicate with diverse groups of people. They form a network of highly qualified and concerned people who are capable of implementing a wide range of activities useful to the community.

What really sets Master Gardeners apart from other home gardeners is their special training in horticulture. In exchange for their training, persons who become Master Gardeners contribute time as volunteers, working through their local Extension office to provide horticulture-related information to their communities.

Is the Master Gardener Program for Me?

Ask yourself these questions:

  • Do I want to learn more about the culture and maintenance of many types of plants?
  • Do I enjoy participating in practical training programs?
  • Do I look forward to sharing my knowledge with people in my community?
  • Do I have enough time to attend training and to complete the volunteer service?

If you answered yes to these questions, the Master Gardener program could be for you.

Volunteer Commitment

In exchange for training, participants are asked to volunteer time to their county Extension program. The type of service done by Master Gardeners varies according to community needs, and the abilities and interests of the Master Gardeners.

Some Master Gardeners answer telephone requests for information related to gardening. Master Gardeners may speak to local groups and conduct workshops. They may help with community garden projects, work with youth, answer gardening questions at events or assist their Extension agent with news or radio releases related to gardening. The Master Gardener Coordinator in the County Extension office decides how volunteer time can be best utilized.

Master Gardeners are representatives of the Texas A&M AgriLife Extension Service. In all volunteer work related to the program, Master Gardeners follow the research-based recommendations of Texas A&M AgriLife Extension and the Texas A&M Code of Conduct.
