Chrysanthemum (Mums): Growing, Choosing and Troubleshooting Guide
Chrysanthemums can turn a fading garden into a spectacular fall display – but choosing and growing mums successfully is not always as simple as buying a flowering pot in September. Some chrysanthemums are reliable hardy perennials, others are primarily seasonal plants, and cultivars differ in bloom time, flower form, size, hardiness, and garden performance. Use these guides to choose the right mums, extend the flowering season, help plants survive winter, solve common problems, and create better autumn plantings.
Choose the Right Mums for Your Garden
Start by understanding what kind of chrysanthemum you are buying. Garden mums and florist mums are not necessarily interchangeable, particularly when winter hardiness matters. Learn the difference between garden mums and florist mums, then find out which mums are perennial and most likely to return each year.
Flower form is another part of the decision. Chrysanthemums range from familiar daisy-like blooms to decorative, pompon, spider, quilled, incurved, reflexed, and spoon-shaped flowers. Explore the 13 major types of chrysanthemum to understand how dramatically cultivars can differ.
Plan Mums for a Longer Fall Display
Not every chrysanthemum flowers at the same time. Depending on the cultivar and climate, mums may begin blooming in late summer, reach their peak in early or mid-fall, or continue flowering until frost. Combining plants with different flowering periods creates a much longer display than planting a single bloom season.
Use Gardenia’s chrysanthemum bloom-time guide to compare early, midseason, and late mums. Then build a more layered planting with the best companion plants for chrysanthemums and these best fall flowers for an autumn garden.
Plant and Grow Chrysanthemums Successfully
For the strongest plants and heaviest flowering, chrysanthemums generally need plenty of sun, good drainage, consistent moisture, and adequate growing space. Timing matters too. A hardy mum planted in spring has months to establish roots, while a flowering plant installed shortly before winter may have much less chance to settle in before freezing conditions arrive.
Follow the complete guide to growing magnificent chrysanthemums for advice on planting, watering, feeding, pinching, and seasonal maintenance. If you have bought a decorative fall pot, see whether you can plant potted mums in the ground and what improves their chances of becoming established garden plants.
Keep Mums Blooming – and Help Them Return Next Year
If your chrysanthemum grows well but produces few flowers, the cause may be insufficient sun, excessive fertilizer, incorrect pruning or pinching, stress, or artificial light at night. Chrysanthemums respond to shortening day length, so nighttime lighting can delay or disrupt flower-bud development in some situations. Use the guide to why mums are not blooming to work through the most likely causes.
Once flowering ends, winter survival becomes the next challenge. Hardiness alone does not guarantee a return: planting time, drainage, root establishment, winter wet, and container exposure all matter. Learn how to overwinter mums in the ground and in pots and how to give perennial chrysanthemums a better chance of resprouting in spring.
Diagnose Chrysanthemum Problems and Explore Their Other Uses
Wilting, yellow foliage, brown or spotted leaves, distorted shoots, damaged buds, and poor flowering can have very different causes. Before treating the plant, identify whether the problem is cultural, environmental, pest-related, or caused by disease.

Chrysanthemums also have a fascinating history beyond ornamental gardening. Certain flowers are traditionally used for chrysanthemum tea, while pyrethrins obtained from particular chrysanthemum species have long been used in botanical insecticides.
