[note 2]It works towards this objective by providing activities that help member clubs develop and publicize new or improved gardening techniques.

People living in a location without local garden clubs can become a member-at-large[note 3] and participate in TGOA/MGCA programs.

Botanist Liberty Hyde Bailey was awarded the first Johnny Appleseed Memorial Medal by Men's Garden Clubs of America in 1948.

[7][8][9][10][11] Sometimes affiliation with TGOA/MGCA leads to the formation of a more narrowly focused garden club, as is the case with the Corvallis Rose Society.

[note 11] The table that follows shows conservative estimates of total annual contributions made by all TGOA/MGCA clubs to their communities.

TGOA/MGCA holds annual national conventions that are hosted by local clubs in cities across the United States.

[13] The purpose of each convention is to learn from other gardeners, tour local gardens and horticultural sites, participate in educational workshops and seminars, share information on service projects and fundraisers, present national awards to club members, and conduct a business meeting of the organization.
