In gardens, Chrysanthemum, or “mums,” are a popular choice because of their vibrant colors and attractive qualities. It’s a common goal for gardeners to find strategies to keep their mums blooming during the winter months.
Tender perennials, such as mums, are more susceptible to frost damage than hardy perennials. If the plants are not covered or protected in some way, frosts are likely to inflict damage to mums.

When it comes to protecting your mothers from the harsh winter cold, there are a number of issues to consider. In this post, we’ll talk about the finest kind of mothers for dealing with frost, as well as the advantages and disadvantages of planting mums in the ground as opposed to pots.
Mums Container Culture
According to the Jim Jenkins Lawn and Garden Center, potted mums bloom joyfully from late summer through fall if they are positioned in full light and protected from late afternoon heat. In order to avoid drying out, chrysanthemum potted plants need to be watered daily because they are such moisture hogs. Trim back the top growth to within an inch of the earth as fall flowers fade. Removing the blooms helps the mums have a greater chance of surviving the winter, whether they’re indoors or outside.
Frost-Free, Not Worry-Free
Keep potted chrysanthemums outside in the winter if temperatures don’t fall below 32 degrees Fahrenheit. They should start growing again in the spring. But in mild winter climates, the mothers may suffer from being overly wet during the season. To avoid becoming flooded, keep potted plants on a covered, unheated porch or in a carport. Remove chrysanthemums from their pots if there is no protected place. To avoid the root rot that can destroy chrysanthemums in the winter, cover the root balls with sand or mulch and use it to shield them from the wind and cold.
Mums Cold-Snap Precautions
Perennials in pots are often two hardiness zones more delicate than their indicated in-ground hardiness rating would imply. This would limit the hardiness of potted garden mums to USDA zone 9, which has an average minimum temperature of 20 to 30 F. The plants should be watered thoroughly when frost approaches, and they should be moved to a covered area or placed in groups of potted plants on grass or soil, not on concrete or decking, so that they can absorb heat and moisture. You can protect your chrysanthemums from frost by covering them with spun fleece fabric or even a sheet. Mulch around the pots if the cold lasts longer than a few of days.
Indoor Mums Option
Garden mums, being sensitive perennials, require a resting period before blooming again the next year. Even if you bring them indoors, they will not go into dormancy because they will not be exposed to sunlight. If you arrange your potted chrysanthemums in a location that gets full sun or additional light, you can bring them indoors when frost is imminent. The University of Missouri recommends a daytime temperature of 70 to 75 degrees Fahrenheit and a nighttime temperature of 60 degrees Fahrenheit.
How cold is too cold for mums?
Moms have a certain tolerance for cold. Mums can withstand temperatures as low as 20 degrees Fahrenheit, making them ideal for containers. They can tolerate temperatures between 90 and 100 degrees Fahrenheit, but they’ll require plenty of water and some protection from the sun.
When bringing moms indoors, what temperature should you keep them at? Moms who want to stay inside can choose this option.

Does frost harm mums? A light fall frost should be no problem for most garden mothers. Cover your plants at night if there are freezing warnings. Plants that are allowed to remain unpruned in cold climates do better in the cold than those that have had their dead foliage removed.
For how long may a mother be out and about? Don’t choose flowers that have already started to wilt. It is possible to cultivate garden mums in containers, or to put them with other plants and flowers in the garden. Floral displays can endure anywhere from a few days to a few weeks, depending on weather conditions and how far along the plant’s blooming process was when it was bought.

Best Time of Year to Plant Mums

To Prune or Not to Prune
A common practice for most plants is pruning, which entails cutting down and eliminating certain sections of the plant in order to encourage its development.. If you’re trimming mums in late fall or early winter, don’t cut down to the ground, since this could harm the plant’s ability to retain heat in the cold.
Trim the stem only a few inches from the ground so that the plant has a good amount of stem to sprout from in the future.
Final Thoughts
Frost does not have to be a death sentence for you mums. Because they are perennials, hardy mums are more than capable of surviving and re-emerging in the springtime. Even though your mums are dormant, they will still need some winter care to keep them healthy and ready for the spring when they awaken from their slumber.
