This Show and Judges Handbook, 2019 Revised Edition, is being revised. It will be available later this year. The new edition will replace all prior editions and will be the guide for shows sponsored by the National Chrysanthemum Society, Inc., U.S.A. and its chapters. This handbook presents the classification system and show policies that NCS recommends be used in the exhibition of the chrysanthemum, as well as the current criteria for exhibitors and requirements for judges, as established by the NCS Judges Schools and Credentials Committee.
