Hardy Chrysanthemum Care Tips

Proper care is essential for the health and longevity of your garden mums. Here are some key care tips to keep in mind:

Planting and Maintenance

Plant mums as soon as the soil warms in the spring for optimal growth.
Shear back the plant from late spring to mid-July to encourage bushier growth and delay flowering until fall.
Fertilize regularly throughout the growing season for abundant blooms.
Cut plants down to about six inches after blooms fade and cover with straw or mulch for winter protection.
Lift and divide established plants every two to three years to promote healthy growth.

Light and Soil

Mums thrive in full sun but can tolerate some shade, especially in warm climates.
Plant them in rich, well-drained soil with a pH of about 6.5 to 6.7.
Avoid planting mums where they might be exposed to bright nighttime light, as it can confuse their blooming cycle.

Watering and Temperature

Mums require regular watering, especially during the early growing season and when flower buds mature.
Ensure soil remains moist but not soggy to prevent root rot.
Provide extra protection for plant roots in cold regions to survive harsh winter freezes.

Fertilizing and Pruning

Feed mums with nitrogen and potassium during the vegetative phase to promote healthy roots and blooms.
Start a feeding cycle in early spring and stop feeding after July to prevent frost damage.
Prune mums by pinching back the center leaves every time the plant grows six inches to promote bushier growth and increase blooming.

By following these care tips, you can ensure your garden mums thrive and bloom beautifully in your garden.

Types of Hardy Chrysanthemums

There are many varieties of garden mums available, categorized by flower shape. Some popular classifications include:

Anemone
Pompom
Regular Incurve
Single or Daisy
Spider

Shorter varieties of mums are known as cushion mums, which are perfect for borders or containers. While you can find some named cultivars at garden centers, exceptional varieties and exhibition mums may need to be grown from seeds or ordered from specialty nurseries.

Some popular chrysanthemum varieties include ‘Clara Curtis,’ ‘Mary Stoker,’ ‘Apricot Moneymaker,’ ‘Ruby Mound,’ ‘Patriot,’ and ‘Tripoli.’

How to Propagate Hardy Chrysanthemums

You can propagate mums through division, seeds, or cuttings. The most straightforward method is division, where you separate and replant sections of an established plant. Cuttings can also be rooted in water or soil to create new plants.

Growing Hardy Chrysanthemums From Seeds

While mums can grow from seeds, it’s best to use purchased seeds to ensure the resulting plant is true to the parent. Start seeds indoors six to eight weeks before the last frost date and transplant them outdoors after hardening them off.

Potting and Overwintering Hardy Chrysanthemums

Repotting is crucial for the longevity of your mums, as they can quickly become root-bound in their containers. Ensure the roots have good contact with the soil and water the plant thoroughly after repotting. Overwintering is important, especially in cold regions, to protect plants from freezing temperatures and ensure their survival for the next growing season.

Common Pests and Problems

Mums can be susceptible to pests like aphids, thrips, and spider mites, as well as fungal diseases and viruses. Regular inspection and proper care can help prevent these issues. Additionally, keeping mums in containers designed for indoor growth can help avoid common problems associated with outdoor planting.

In conclusion, hardy chrysanthemums are a beautiful addition to any garden, offering a burst of color in the autumn months. By following proper care tips and maintenance practices, you can enjoy vibrant blooms year after year. So, roll up your sleeves, grab your gardening tools, and get ready to transform your garden with these stunning flowers!
