How to Keep Mums Blooming Through Fall

Fall brings a palette of warm colors and a shift in gardening priorities. As summer’s blooms begin to fade, garden enthusiasts turn their attention to hearty, autumnal flowers. Among these, chrysanthemums, or “mums” as they’re affectionately known, take center stage. With proper care, you can enjoy the vibrant hues of mums throughout the fall season and even beyond. In this comprehensive guide, we’ll explore the secrets to keeping your mums in full bloom when the leaves start to fall.

Choosing the Right Mums

When it comes to prolonging the bloom of mums into the fall, the journey begins with selecting the right mum varieties. Here are some factors to consider:

Early, Mid, and Late-Blooming Mums

To create a stunning and prolonged display of fall color, opt for a mix of early, mid, and late-blooming mum varieties. This strategic selection ensures that your garden remains a tapestry of hues throughout the entire fall season.

  • Early-Blooming Varieties: These mums burst into bloom in early to mid-fall. Varieties like “Sheffield Pink” and “Venus” are excellent choices. They add a splash of color when other garden plants are beginning to fade.
  • Mid-Blooming Varieties: Mid-season mums, such as the “Country Girl” or “Cambodian Queen,” bridge the gap between early and late bloomers, providing continuity of color and interest.
  • Late-Blooming Varieties: Late-blooming mums, like “Emperor of China” or “Ruby Mound,” are the showstoppers of late fall. They ensure that your garden remains vibrant even as the days grow shorter.

Hardy vs. Florist Mums

Another vital consideration is the type of mums you choose: hardy or florist mums.

  • Hardy Mums: These are bred to withstand cooler temperatures and are the go-to choice for fall gardens. They are robust and require less pampering to keep blooming.
  • Florist Mums: While incredibly stunning, florist mums may demand more care to maintain their bloom. These are often sold as potted plants and may need special attention to transition them into the garden successfully.

Planting Mums

Proper planting sets the stage for a successful mum-growing season. Here are some planting tips:

Early Planting

Mums should ideally be planted in the spring or early summer. Planting them at this time allows their root systems to establish themselves before the fall bloom. This is essential for ensuring that they have a solid foundation to draw nutrients and water from as they produce blooms.

Sunlight Requirements

Mums are sun-lovers, and to keep them blooming beautifully through the fall, they need at least six hours of direct sunlight daily. Choosing a sunny spot in your garden or on your patio is crucial for their health and vitality.

By selecting the right mum varieties and planting them early in the season with ample sunlight, you’re setting the stage for a stunning fall display. But the journey to keeping mums blooming extends beyond planting; it also involves proper care and maintenance.

Pruning and Deadheading

Pruning and deadheading are two essential practices to prolong the bloom of your mums:

Pinch for Bushiness

Early in the growing season, consider pinching about 2 inches off of the tips of the mum stems. This may seem counterintuitive, but it’s a strategic move to encourage branching. As a result, you’ll have a bushier mum plant with more potential flower buds. This simple act can significantly impact the density and duration of the bloom.

Remove Spent Blooms

Deadheading, or the removal of spent blooms, is a powerful technique to ensure your mums continue to produce new flowers. As soon as a flower starts to fade, it’s essential to remove it by pinching it off above a set of leaves. Remove the bud before its completely dead. This practice prevents the plant from diverting energy into seed production, channeling it instead into generating more blooms.

Pruning and deadheading can seem meticulous, but they pay off handsomely in an extended and vibrant fall bloom.


Fertilization is a critical aspect of mum care for continuous blooming:

Balanced Fertilizer

In the early summer, apply a balanced, slow-release fertilizer to your mum plants. Balanced fertilizers typically have an equal ratio of nitrogen, phosphorus, and potassium (N-P-K). Avoid excessive nitrogen, as it can lead to excessive foliage growth at the expense of flowering. The right nutrients provided at the right time can make all the difference in your mum’s performance.


Proper watering is essential to maintain consistent soil moisture:

Deep, Regular Watering

Mums prefer soil that is evenly moist but not waterlogged. To achieve this, water your mums deeply when the top inch of soil feels dry to the touch. Watering in the morning allows the foliage to dry before evening, reducing the risk of fungal diseases.

A common mistake is to water the foliage itself. It’s best to direct the water towards the base of the plant to keep the leaves dry, which can help prevent mold and mildew.

Maintaining consistent moisture is critical, as mums are sensitive to both drought and waterlogging.


Mulching around your mum plants serves multiple purposes:

Apply a Layer of Mulch

Spread a layer of organic mulch, such as wood chips or straw, around your mum plants. Mulch acts as a protective barrier, conserving soil moisture and regulating soil temperature. It also helps deter weeds from competing for resources with your mums.

A well-mulched garden bed retains soil moisture, ensuring that the roots stay cool and the soil doesn’t dry out too quickly. This promotes longer-lasting blooms and healthier mum plants.

Frost Protection

Late fall frosts can pose a threat to your mum blooms:

Keep an Eye on the Weather

As the fall season progresses, keep a close watch on the weather forecast. If frost is expected, especially in late fall, take precautions to protect your mums.

Cover them with a light cloth or newspaper overnight to shield them from frost damage. This simple measure can significantly extend the bloom period, allowing you to enjoy your mums’ vibrant colors even longer.

Dividing Mums

Over time, mums can become crowded, leading to diminished bloom quality:

Rejuvenate with Division

Every few years, consider dividing your mum clumps in the spring. This practice rejuvenates the plants by allowing you to replant the healthiest portions. This fresh start results in more vibrant blooms and healthier plants.

Container Planting

For gardeners who seek more control over mum care, container planting offers versatility:

Versatile Containers

Planting mums in containers provides flexibility in managing their environment. You can easily move containers to sheltered locations during cold spells, ensuring your mums remain protected.

Additionally, container planting allows you to strategically display your mums for maximum visual impact, enhancing your garden’s overall aesthetic.

In conclusion, the art of keeping mums blooming through the fall is a combination of careful selection, early planting, proper care, and thoughtful maintenance. By choosing the right mum varieties, providing them with the right conditions, and practicing essential techniques like pruning, deadheading, fertilizing, and mulching, you can ensure your mums grace your garden with their beautiful blossoms for an extended period.
