La cultiver
- Propagation
- Division, Cuttings
- When to plant
- Spring, Summer
- Overwintering
- In colder climates, cut back the dead foliage after the first frost. Mulch heavily around the base of the plant to protect the roots from freezing and thawing cycles. In very cold regions, consider planting them in pots that can be moved to a sheltered location like an unheated garage or shed.
- In containers
- Chrysanthemums do well in containers, especially smaller varieties. A pot at least 8-10 inches in diameter is recommended to give the roots adequate space.
Division
- In early spring, carefully dig up the established clump.
- Gently separate the clump into smaller sections, ensuring each section has roots and shoots.
- Replant the divisions immediately into well-prepared soil.
- Water thoroughly after planting.
Cuttings
- In late spring or early summer, take 4-6 inch cuttings from healthy, non-flowering stems.
- Remove the lower leaves and dip the cut end in rooting hormone.
- Insert the cuttings into a moist potting mix.
- Keep them in a warm, bright location and mist regularly until roots form.
- Transplant rooted cuttings into individual pots or the garden.
