About Us

Gardening Volunteers of South Texas is a non-profit, 501(c)3 organization, founded in 2002. It is organized exclusively for educational, civic, scientific and charitable purposes. Our fundamental efforts are focused on water conservation, and environmental awareness while working collectively with fellow private, public and educational organizations to serve as an educational resource for the community. GVST strives to explore areas of research and development of horticulture and agriculture practices, and products within our local greenhouse and community outreach gardens. In our region we explore in research and development of horticulture products within our local greenhouse and community outreach projects.

Neighborhood Fairs

GVST will come to your neighborhood for a Saturday morning Neighborhood Landscape Fair, presented in partnership with San Antonio Water System.

We bring lots of information about watersaving landscaping and gardening, drought-tolerant plants and latest rebate and coupon programs offered by SAWS.  Other activities are often offered, such as “Ask the Expert”, tool sharpening and, based on availability, drought-tolerant plant sales.

Neighborhood Landscape Fairs are coordinated through Homeowner, Neighborhood and Property Owner Associations.

GVST started as a group of gardeners that were part of the BCMG program.  These members wished to take a different path and with the encouragement of several prominent garden mentors, began the organization in 2002. Today, it is great to have members that are not only in the Master Gardener program but members of other organizations such as SA Botanical, Native Plant Society, Rose Society and other groups that have as their focus good gardening in the South Texas area.

GVST’s original “charter group” were all members of Texas A & M’s Dr. Jerry Parsons’ research and development team that propagated plants at the old Peterson’s greenhouse on Seale Road. Calvin Finch, who was then Conservation Director at SAWS, saw the potential in a new outreach group with a “Can do! When do we start?” attitude. With Calvin’s encouragement, we formed a non-profit 501c3 corporation.

Calvin suggested that “educator turned Hill County Gardener” Tom Harris, Diane Dondero and Anne Schiller get things organized. Tom and Anne remain active today. When Diane passed away a few years ago, GVST planted a tree in her memory at Mitchell Lake Audubon Center.
