Mums, or Chrysanthemums, are a fall garden favorite that brings a burst of color as the summer flowers fade. Their vibrant hues, ranging from bright yellows and reds to deep purples and oranges, can completely transform your garden into a stunning autumn display. However, many gardeners struggle to keep their mums blooming throughout the entire fall season. With the right care, you can extend their bloom period and enjoy their beauty well into the colder months.
In this article, we’ll cover the comprehensive steps to ensure that your mums continue to thrive and bloom in your garden all fall. We’ll discuss planting, pinching, deadheading, watering, fertilizing, and more, ensuring you have the knowledge to maintain your mums’ health and vibrancy.
1. Planting Your Mums at the Right Time
One of the most important factors in ensuring long-lasting blooms is planting your mums at the right time. While mums are typically sold in the fall, they should ideally be planted in the spring or early summer for the best chances of survival and bloom longevity.
Planting mums in the spring gives the roots enough time to establish themselves before the colder weather sets in. Well-established roots help the plant survive the winter and allow it to bloom again the following fall. If you purchase mums in the fall, treat them as annuals, as they may not survive the winter if planted too late.
To ensure success when planting mums, follow these steps:
- Choose a sunny location: Mums need full sun to thrive. They should receive at least 6 hours of sunlight each day for optimal growth and blooming.
- Prepare the soil: Mums prefer well-draining soil that is slightly acidic, with a pH level between 6.0 and 6.5. If your soil is heavy or clay-like, amend it with compost or organic matter to improve drainage.
- Space them properly: Mums need room to grow, so plant them at least 18 inches apart to allow good airflow, which will reduce the risk of fungal diseases.
2. Pinching Back for Fuller Growth and More Blooms
Pinching back your mums is an essential step to encourage bushier growth and more abundant blooms. Pinching is the process of removing the tips of new growth to stimulate the plant to produce side shoots, which results in a fuller, more compact plant with more flowers.
Here’s how to pinch your mums:
- Pinch in early summer: Start pinching your mums in the late spring or early summer, once they’ve grown about 6 inches tall.
- Remove the top 1-2 inches: Using your fingers or garden shears, remove the top inch or two of each stem. This will encourage the plant to branch out and produce more flowers.
- Repeat the process: Continue pinching every 2-3 weeks until mid-July. After mid-July, stop pinching to allow the plant to form buds for fall blooming.
Pinching helps prevent your mums from becoming leggy and ensures they develop a dense, rounded shape with more blooms. This practice will also prolong the blooming period into late fall.
3. Regular Watering for Healthy Blooms
Mums need consistent moisture to thrive, but overwatering can lead to root rot and other fungal diseases. To strike the right balance, keep the soil evenly moist but not soggy. Water deeply at the base of the plant to ensure the roots get enough moisture, but avoid wetting the foliage.
Follow these watering tips to keep your mums healthy:
- Water regularly: Mums prefer to be watered consistently, especially during hot or dry weather. If the soil is dry to the touch, it’s time to water.
- Mulch to retain moisture: Applying a layer of mulch around your mums helps retain moisture in the soil and prevents it from drying out too quickly. It also helps regulate soil temperature and reduces weed growth.
- Avoid overhead watering: Wet leaves can promote fungal diseases, so water your mums at the base of the plant to keep the foliage dry.
4. Fertilizing for Continued Blooms
Fertilizing your mums is crucial to providing the nutrients they need for prolonged blooming. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium (such as a 10-10-10 or 20-20-20 blend) works best.
Here’s how to fertilize your mums:
- Feed regularly: Apply a balanced fertilizer every 2-4 weeks during the growing season. Begin feeding your mums in the spring and continue until the buds start to form in late summer.
- Stop feeding once buds appear: Once the flower buds have formed, stop fertilizing, as over-fertilization can lead to excessive foliage growth at the expense of blooms.
- Use organic options: If you prefer organic gardening, compost, or organic fertilizers such as fish emulsion or worm castings are excellent choices for feeding mums.
Proper feeding ensures that your mums have the energy they need to produce a bounty of flowers throughout the fall.
5. Deadheading to Extend the Blooming Period
Deadheading, or removing spent flowers, is a simple but effective way to extend the blooming period of your mums. When you remove the faded blooms, the plant redirects its energy into producing new flowers rather than setting seed.
Follow these deadheading tips for prolonged blooms:
- Remove spent flowers regularly: Check your mums every few days for faded flowers, and snip them off just below the flower head.
- Be gentle: Use sharp, clean shears or your fingers to remove the flowers without damaging the surrounding foliage or stems.
- Keep an eye on new blooms: As you deadhead, you’ll likely notice new buds forming, signaling that the plant is preparing to produce more flowers.
Regular deadheading encourages continuous blooming and keeps your mums looking fresh and vibrant well into the fall.
6. Protecting Your Mums Through Winter
If you want your mums to bloom again next fall, it’s important to protect them through the winter months. Hardy mums can survive the winter in most regions, but they need a little extra care to ensure they make it through the cold.
Here’s how to protect your mums in the winter:
- Mulch heavily: After the first frost, apply a thick layer of mulch (3-4 inches) around the base of your mums to insulate the roots. Straw, leaves, or evergreen boughs work well.
- Avoid pruning in fall: Resist the urge to prune your mums back in the fall. The foliage will protect the crown of the plant from freezing temperatures. Instead, wait until early spring to prune away any dead or damaged growth.
- Water sparingly in winter: Mums go dormant in the winter, so they don’t need as much water. Water only if the soil is completely dry, and avoid watering during freezing conditions.
By taking these steps, you’ll give your mums the best chance of surviving the winter and coming back stronger next year.
Conclusion
Keeping mums blooming all fall is easier than you might think, as long as you follow a few key steps. By planting them in the right location, pinching back in the summer, watering consistently, fertilizing, deadheading, and providing winter protection, you can enjoy their vibrant colors throughout the season.
