Mums, or chrysanthemums, are fall favorites that bring vibrant colors to gardens. To get the biggest and healthiest blooms, proper fertilization is key. In this guide, we’ll explore when and how to fertilize mums for stunning results.
Why Fertilize Mums?
Mums are heavy feeders and require a nutrient-rich environment to thrive. Fertilizing ensures they grow strong stems, lush foliage, and large, vibrant flowers. Without proper nutrition, mums may produce fewer blooms or look leggy and weak.
When to Fertilize Mums
- Spring (New Growth Stage)
Start fertilizing mums when you see new growth in spring. This is typically when they emerge from dormancy. Feeding them early provides the nutrients they need to establish strong roots and foliage. - Mid-Summer (Bud Formation Stage)
Fertilize again in mid-summer as buds begin to form. This boosts their energy for flower production, ensuring bigger and more abundant blooms. - Late Summer to Early Fall (Final Feed)
Apply the last round of fertilizer in late summer, about six weeks before the first expected frost. This strengthens the plants and prepares them for their blooming season. Avoid fertilizing too late, as it can encourage excessive foliage growth instead of flowers.
How to Fertilize Mums
- Choose the Right Fertilizer
- Use a balanced fertilizer, such as 10-10-10 or 15-15-15, in the spring and early summer.
- Switch to a bloom-boosting fertilizer, like one high in phosphorus (e.g., 5-10-10), as buds begin to form.
- Application Tips
- Granular Fertilizers: Sprinkle granules around the base of the plant, keeping them 2-3 inches away from the stem to avoid root burn. Water thoroughly to help nutrients soak into the soil.
- Liquid Fertilizers: Mix according to package instructions and apply directly to the soil or as a foliar spray for quick absorption.
- Frequency
- Feed mums every 4-6 weeks during the growing season. Be consistent, but don’t overdo it—excessive fertilization can lead to weak, floppy stems.
Additional Tips for Healthy Mums
- Pinching: Regularly pinch back the growing tips in late spring and early summer to encourage bushier growth and more blooms. Stop pinching about 90 days before the first frost.
- Watering: Keep the soil evenly moist but not soggy. Mums are sensitive to dry conditions during their blooming period.
- Mulching: Add a layer of mulch to retain moisture and prevent weed competition.
Conclusion
Fertilizing mums at the right times with the right nutrients ensures stunning, long-lasting blooms that will make your garden the envy of the neighborhood. Follow these simple tips, and you’ll enjoy a vibrant display of chrysanthemums every fall. Happy gardening!
