When is the best time to plant garden mums?
Spring is the best time to plant garden mums (Chrysanthemum x morifolium) in Iowa. Mums planted in spring survive the winter much better than those planted in fall. Spring planted mums have the opportunity to grow and establish themselves over a period of several months. Fall planted mums have little time to establish themselves before winter and are much more likely to be severely damaged or destroyed in winter.
