Chrysanthemum stunt viroid spreads most efficiently through vegetative propagation, where infected mother plants pass the viroid to cuttings. It is easily transmitted through grafting, sap contact, and the use of contaminated tools or hands. Seed and pollen transmission is possible but variable, with evidence of transmission in both chrysanthemum (under certain conditions) and tomato.
