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.
Can mums be in hot weather?
Mums, especially early season varieties, are sensitive to high temperatures during flower initiation. This phenomenon is known as “heat delay.” When short days are provided to initiate flowers, heat delay occurs when temperatures exceed approximately 85 degrees Fahrenheit.
How do you take care of mums in hot weather?
Maintain their daytime temperatures near 70 to 75 degrees Fahrenheit, and avoid exposing them to high heat and frost. Check the mums’ soil moisture daily, and water the mums when the top 1 inch of soil begins to dry. Water the soil surface using a watering can until moisture begins to drain from the bottom of the pot.
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.
Is 90 degrees too hot for mums?
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.
Are mums OK in the sun?
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 let my mums bloom in summer?
Just how early depends of course on what growing zone you might happen to live in. But in most cases, it is far earlier than the desired fall blooming season that mums have become famous for. Pinching back blooms in the summer creates a robust and thicker plant with more blooms.
Should I cut back mums in summer?
Really, the last part of June up to July 4th is a great time, but doing it much more into July risks your mum from not being able to re-produce blooms by Autumn’s arrival. Do not trim them to be lower than that as it could damage the plant or the plant not grow enough again to produce a bloom this fall.
How do you keep mums blooming in the summer?
Pinch each time the mums grow to about 6 inches high, reducing the stem length to about 4 inches. Pinching encourages branching, which results in more buds — but pinching after July removes the buds and reduces bloom.
Can mums survive frost?
Most garden mums should be able to endure a light fall frost. Cover the plants at night when freeze warnings are in effect. However, if you are in a cold climate, leaving the dead foliage on the plants has been found to help the plant survive colder temperatures better than pruned plants.
Can mums survive the winter in pots?
Mums can survive light frosts and cold fairly easy, but a hard freeze can kill roots in pots permanently. Once potted mums have endured a hard freeze, their chances for surviving winter are slim. Cut mums back to within a few inches of the soil line before bringing indoors.
How do you keep potted mums alive outside?
Other essentials in caring for mums planted outdoors include: Give mums plenty of space. Water, but not too much. Deadhead. In colder climates your mums may need to be mulched using leaves, wood chips, or straw. If frost gets your mums, don’t fret.
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. Keep mums outdoors until the foliage and flowers die back after the first frost.
Can mums survive 32 degrees?
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 indoors?
Indoor Mum Care: Growing Chrysanthemums Indoors. Growing chrysanthemums indoors is easy and requires little special care beyond watering, good soil and drainage. Once the blooms are spent, you can keep the plant around for its deeply etched foliage.
Should I water mums everyday?
Mums don’t like to get dry between waterings, so make sure you water them at least every other day and especially if they start looking wilted. Just like potted mums, water them at the soil level instead of on top of the blooms. Watering the foliage can cause disease.
Can mums tolerate shade?
Mums thrive in full sun but can handle a bit of shade. Generally, flowering will be most profuse if they are grown in full sun. However, in warm climates, the plants often appreciate some shade during the heat of the afternoon.
Do potted mums come back?
Potted mums are autumn classics, with late-season color that boosts curb appeal or brightens a Thanksgiving table. Treat your potted mums with care, and they’ll come back whether you maintain them in the pot or plant them out in the garden.
