All About DCMGA

The Denton County Master Gardener Association (DCMGA) is a volunteer program designed to grow horticultural information throughout Denton County.   To become a Denton County Master Gardener, a participant attends 70 hours of instruction, conducted under the guidance of the Denton County Extension Agent in horticulture, then shares this knowledge by donating 70 hours of volunteer service back to the community.   We work on dozens of projects each year, as well as three special projects:  the annual Garden Tour and Plant Sale in the spring and the Fall Garden Festival in October.

We would like to encourage anyone who is interested in becoming a Denton County Master Gardener to submit an application to join our next class.   We also invite college students majoring in horticulture to apply for our scholarship.

Our Horticulture Agent

The Denton County Master Gardener Association is under the guidance of the Denton County Horticulture Agent, Janet Laminack. Janet began working as the Denton County Extension Agent in horticulture in September 2008.   See more about Janet’s bio as well as some of her videos and online gardening articles on our Horticulture Agent page.

Special Events

In addition to participating in dozens of educational projects and speaking engagements and answering hundreds of questions, the DCMGA presents three major events each year.  In the Spring, the annual Garden Tour and Plant Sale have become much-anticipated events with Denton County residents.  The tour allows visitors to view some of our member’s gardens for inspiration and to see how the owners have solved common gardening problems, while the Plant Sale includes plants that thrive in our sometimes difficult North Texas climate.  In October, our annual Fall Garden Fest is a fun and educational event.  Information about currently scheduled events can be found on the Upcoming Events page.
