Membership in the Tri-City Garden Club is limited to 100 members, 50 from Illinois and 50 from Iowa, by the by-laws.  Annual dues are $80.  Membership openings occasionally do become available and require the sponsorship of three active or associate members who have at least two years standing membership.  Applications are submitted to the president who forwards them to the Membership Committee for review.  The Board of Directors approves membership.

The Standing Rules require that each active member serve on committees and annually on a Hostess Committee and as a Hostess Committee Chair once every five years.  Every active member must contribute a minimum of five hours of volunteer work each year on one or more of the Club’s community service projects.  Regular attendance to all meetings is expected.

After ten years, a member may become an Associate Member.  Associate member dues are also  $60 annually.
