What temperature do mums grow in?
Cold Temperatures. In general, mums are hardy in U.S. Department of Agriculture plant hardiness zones 5 through 9, although this can vary slightly by species. According to the USDA map, the lowest minimum temperatures mums can survive are right around 20 degrees below zero Fahrenheit.
Are fancy mums Hardy in winter?
Florist and Fancy Mums. Potted mums sold as gifts -- like those often seen at a florist -- are exotic and not hardy enough to survive winter temperatures, even in USDA zone 9. These mums, which feature unusually shaped or very large flowers, are usually treated as annuals by home gardeners.
How do you keep mums alive in winter?
Increase your mums' chances of survival by surrounding them with a 4-inch layer of mulch after the ground has frozen, and resist the urge to shear off the dead foliage. Yes, that first hard frost of winter will likely kill the plants to the ground, but that doesn't mean the roots are dead.
Can mums survive winter in Zone 9?
Potted mums sold as gifts — like those often seen at a florist — are exotic and not hardy enough to survive winter temperatures, even in USDA zone 9. These mums, which feature unusually shaped or very large flowers, are usually treated as annuals by home gardeners.
What temperature can mums tolerate?
Mums are cold hardy to about 20 degrees Fahrenheit. They can survive hot temperatures from 90 to 100 F, but they'll need plenty of water and a little shade.
Is 80 too hot for mums?
Indoor Mums Option Keep the temperature between 70 and 75 F during the day and 60 F at night, according to the University of Missouri.
Can mums handle warm weather?
Different Types of Mums Given that plants in Zone 5 can withstand temperatures to -20 degrees Fahrenheit (and plants in Zone 3 can survive temperatures of -40 to -30 degrees Fahrenheit), these mums' frost tolerance is pretty high.
Can mums survive 90 degree weather?
Mums prefer cooler temperatures, which can be a problem if you buy them when they're first available and it's still getting to 90°F during the day. In the heat, all the flowers will fade in only a couple of weeks so you'll have to replace them faster if you want to keep up the colorful show through the season.
How long do potted mums last outside?
Garden mums may be grown in containers, or planted in beds with existing shrubs and flowers. Flowers generally last about two or three weeks, depending on the outdoor temperatures and how far along the blooming process was when the plants were purchased.
Are mums OK in the sun?
How Much Sunlight Do Mums Require? Chrysanthemums are sun-loving plants. Although they technically require only 6 hours of sunlight each day, the more light they receive, the better their growth, bloom and hardiness. Slight shade in hot, summer afternoons is appropriate in warmer gardening zones to prevent scorching.
Should I bring my mums inside?
You can leave your garden mums in the ground during winter, especially with a layer of mulch in the cooler zones. However, because potted plants are more susceptible to cold damage, bring your mums indoors for winter safekeeping.
When should I cover mums?
Most garden mums should be able to endure a light fall frost. Cover the plants at night when freeze warnings are in effect. To keep the plant attractive and healthy, snip off any dead blossoms as soon as they wilt.
Can you leave mums outside?
Once your mums stop blooming, you can place them in the ground outdoors once the weather starts to warm. Mums will only bloom once inside but keeping it green until you transplant it outdoors will allow you to enjoy it next season.
How often should you water mums?
every other dayDon't let your mums get too dry or wilt between waterings. Water your potted mums at least every other day. They like to get about 1 inch of water per week. Water at the soil level (the base of the plant) and not on top of the foliage.
How do you care for potted mums outside?
Although mums planted in a spring garden need 6 hours of sunlight, fall potted mums need bright but indirect light. Place them a few feet back from a south-facing window or anywhere in a bright location without direct sun. Keep the mums' soil continually moist, but not soggy, by checking it daily with your finger.
How do you keep mums alive in pots?
Care of Mums in Pots While your plant is in its container, keep the soil moist, but not soaking wet. Mums are thirsty plants, so check them for moisture often. Water them during the morning, so that the leaves have time to dry during the day. Never allow them to wilt.
Characteristics
The chrysanthemum’s large, bright, radial blooms come in a variety of colors ranging from white through yellow, gold, orange and red to deep magenta and purple. There are even many variegated varieties, with darker color on the inner parts of the petal, lightening outward.
Winter Hardiness
Although their exact cold tolerance does depend on the specific variety, most mums grow well in U.S. Department of Agriculture plant hardiness zones 5 through 9. This means they can overwinter in the ground within these zones, and they do so especially reliably in the warmer climates.
Heat Delay
A more significant concern in warmer climates is heat delay, in which high temperatures -- particularly at nighttime -- cause the plant to flower later than it normally would.
Garden Uses
Aside from their temperature preferences, mums prefer full sun and moist, well-drained soil. Because they bloom so reliably in the less showy fall months, gardeners often incorporate them into beds and borders for pops of color.
