Welcome Gardeners

Our Mission

The mission of the St. Louis Master Gardener organization is to provide horticultural information and assistance to the public for community service and gardening pleasure through the volunteer efforts of Master Gardeners.

What we do

St. Louis Master Gardeners have been enriching our community since 1983. From a few people answering the help line at Missouri Botanical Garden and the St. Louis County Extension service, our organization has grown to over 300 active master gardeners who volunteer at the Botanical Garden's Kemper Center as well as throughout the Garden's grounds and with community groups in the St. Louis region.


Fellow gardening lovers can find St. Louis area specific helpful information on a wide range of topics listed on the gardening resources page of this site and educational posts on STLMG Facebook page. Master gardeners stay current by attending continuing education classes and events posted on the members only calendar. Learn how to become a master gardener HERE.
