==Cultivation==
===Propagation===
Plant seeds of plants in the charms and cascades groups of Chrysanthemums in late winter to spring at 55-61F (13-16 C). Rubellum group should be sown at the same temperatures in the spring, or by division in fall or early spring. In colder climates sow the seeds of annual types in a cold frame during early spring or ''in situ'' in spring to early summer, and in mild climates sow them ''in situ'' during autumn for them to bloom early early in the season the next year.
Exhibition types which are overwintered can be used to get basal cuttings - for those that are late flowering take the cuttings in early to mid-winter. All other types of Chrysanthemum cuttings can be taken early in spring. Root cuttings at 61F (16C) in a sandy potting mix, preferably soilless. Protect from cold, in cold frame if necessary. Maintain ventilation if possible. Hardening is possible beginning in mid-spring.
===Pests and diseases===
Susceptible to aphids, earwigs, nematodes, capsid bugs, leaf miners, whiteflies, fungal rot, gray mold (Botrytis), powdery mildew, white rust, and viruses. Viruses can result in puckering of the leaves, yellow marks or stunt the growth. Used as food plants by the [[larva]]e of some [[Lepidoptera]] species — see [[list of Lepidoptera which feed on Chrysanthemum]].
