A Bit About Mums
Before you begin the winterization process, it’s essential to understand the different types of mums and their hardiness. Hardy mums, also known as garden mums, are the best choice for overwintering as they can survive freezing temperatures.
When selecting mums for your garden, look for varieties that are suited for your hardiness zone. Hardy mums typically thrive in Zones 5-9, with some cultivars able to withstand even colder temperatures. For example, ‘Mammoth Daisy Coral’ and ‘Mammoth Daisy Quill Yellow’ are extra hardy varieties that can survive in Zone 3.
Ensure that your mums are planted in a sunny location with well-drained soil to promote healthy growth. If you’re growing potted mums, be aware that container plants are more vulnerable to cold weather and may require additional care in colder climates.
When to Plant
While it may be tempting to plant your mums in the fall when they are in full bloom, it’s best to wait until spring if you want to overwinter them. Fall-planted mums may not establish strong roots in time to survive the winter, so it’s advisable to keep them indoors until spring.
For gardeners in warmer climates (Zones 8 and up), planting mums in late summer or early fall is acceptable, but spring planting is still recommended for optimal results. Whether you’re planting in the ground or in containers, ensure that your mums have ample time to establish themselves before the cold weather sets in.
Necessary Preparations
As winter approaches, take steps to prepare your mums for the colder months ahead. Deadhead spent flowers in early to mid-fall to encourage continuous blooming. Leave the foliage intact after the first frost, as it provides protection for the plant during the winter.
Mulch, Mulch, and More Mulch
One of the key components of winterizing your mums is mulching. Apply a thick layer of organic mulch, such as leaves or straw, around your in-ground plants to provide insulation and protection from freezing temperatures. Ensure that the mulch covers the base of the plants and extends outwards to protect the roots.
Check the mulch periodically throughout the winter and replace it as needed to maintain insulation. In the spring, remove the mulch once new shoots appear and consider reapplying it for moisture retention.
Protect Your Plants
For additional protection, consider placing conifer branches over your plants after the first hard freeze. Avoid using pine needle mulch, as it can smother the plants. Monitor the branches throughout the winter, and remove them once temperatures rise above freezing.
If you live in an area where temperatures remain cold after the holidays, repurpose live branches or spent Christmas trees to provide extra insulation for your mums.
Winter Care for Potted Mums
Potted mums require special care during the winter months to ensure their survival. Before the first hard frost, repot your plants into larger containers and trim them back by about a fourth. Apply a slow-release, high phosphorus fertilizer to nourish the roots over the winter.
When cold weather approaches, bring your potted mums indoors to a cool, dimly lit location where they can go dormant. Monitor the soil moisture and avoid overwatering during the winter. In the spring, watch for new growth and gradually reintroduce the plants to outdoor conditions.
Re-Acclimate to Outdoor Conditions
As the risk of frost diminishes in the spring, acclimate your potted mums to outdoor conditions gradually. Begin by placing them in a shaded spot for short periods and gradually increase their exposure to sunlight. Once the plants are acclimated to full sun, they can be planted in the ground following the same care guidelines for in-ground mums.
By following these steps, you can successfully overwinter your hardy garden mums and enjoy their vibrant blooms year after year. With proper care and attention, your mums will thrive and create a stunning display in your garden.
