Is 10 degrees too cold for pansies?
The 10 degrees’ temperature is too cold for pansies. In some rare cases, the 20 degrees F can be too cold for the pansies to survive. Their leaves and flowers grow best at 40 degrees F. But the plant can survive in cold temperatures up to minus 10 degrees Celsius. Typically, the minus degree temperature is unbearable.
Are pansies hardy perennials?
Perennials can grow as hardy biennials or annuals, depending on their location, according to Utah State University Extension. Pansies prefer temperatures during the night just a bit above freezing with 40 degrees considered ideal. During the day, pansies thrive in temperatures in the high 50s and low 60s.
What is the best temperature for pansies in Utah?

Pansies prefer temperatures during the night just a bit above freezing with 40 degrees considered ideal. During the day, pansies thrive in temperatures in the high 50s and low 60s.
How do you keep pansies from dying in the summer?
Even with these more heat tolerant pansies, if you have temperatures that regularly go over 70 degrees Fahrenheit (21 Celsius) in the summer, they may struggle and wilt a little. Give them partial shade, fertilize lightly, and deadhead throughout the hot months to maximize blooms.
At what temperature should I bring my pansies in?
The reason for these specific planting dates is because pansies require soil temperatures between 45° F and 65° F for best growth. Pansies planted after soil temperatures go below 45° F often appear stunted, develop stunted, pale green leaves and flower poorly.

Can pansies survive a light frost?
With the proper care and preparation, your beautiful pansies can survive frost. They are particularly robust in Zones 4-8. Pansies can endure light frosts and even prolonged snow coverage. In Zones 9-11 where the climate is warmer, the pansies can have flowers during the winter.
Can pansies survive 35 degrees?
Pansy. Pansies have a tolerance to low-temperatures and actually thrive in cool weather (40°-60°F) (Kwon 1992). They are capable of surviving temperatures down to the single digits, but when the air temperature drops below 25°F, pansy foliage will wilt and turn a gray-green color.
At what temperature should you cover your plants at night?
Remember to protect electrical connections from moisture. Cover Plants – Protect plants from all but the hardest freeze (28°F for five hours) by covering them with sheets, towels, blankets, cardboard or a tarp. You can also invert baskets, coolers or any container with a solid bottom over plants.
Should you water pansies before a freeze?
Water plants prior to a hard freeze. This is especially true for pansies in pots. Provide a light pine straw cover to reduce damage during a hard freeze.
When can pansies be put outside in spring?
Set pansy plants in the ground when it becomes workable in the spring. They grow best when soil temperatures are between 45°F and 65°F (7°C and 18°C).
Should you cover pansies in cold weather?
Snow cover actually helps the pansy beds, as it insulates and protects from wind. The Triad has seen some of its coldest weather in many years. Your Pansy or Viola beds may indeed suffer more damage this winter than in past years because of this fact.
How long do potted pansies last?
In the Midwest, the Missouri Botanical Garden calls pansies “short-lived perennials” that are best treated as annuals or biennials, or plants with a two-year life cycle. This means they both germinate and grow one year and then bloom and die the next, Sunday Gardener says.
How cold is too cold for flowers to be outside?
There's no question that flowers need protection from frost and freezing temperatures. Many flowering plants won't survive very long once temperatures dip below freezing and will typically die within a few hours once the mercury hits 28 degrees Fahrenheit.
How hot can pansies get?
Even with these more heat tolerant pansies, if you have temperatures that regularly go over 70 degrees Fahrenheit (21 Celsius) in the summer, they may struggle and wilt a little. Give them partial shade, fertilize lightly, and deadhead throughout the hot months to maximize blooms.
When do pansies bloom?
For instance, if your garden is in the Midwest, you will probably put annual pansies in beds or containers in early spring. They will bloom well until the heat of summer, at which time the plants will wilt and sag and stop producing flowers. But keep them going and you will get blooms again in the fall as temperatures cool off again.
What are some varieties of pansy?
There are some varieties that have been developed for pansy heat tolerance, although they still aren’t crazy about high temperatures. Look for Maje stic Giant, Springtime, Maxim, Padparadja, and Matrix, Dynamite, and Universal varieties.
Can pansies grow year round?
Pansies are a classic cool weather flower, used in most places as an annual. In some warmer and moderate climates, like parts of California, gardeners can grow them year round. In areas where the climate is more extreme with the seasons, it is more typical to grow them during the cooler parts of the year. These flowers generally do not want ...
Are Summertime Pansies Possible?
Whether or not you can get summertime pansies in your garden depends on where you live, your climate, and the variety you choose. There are some varieties that have been developed for pansy heat tolerance, although they still aren’t crazy about high temperatures.
How cold can pansies get?
At the coldest extreme of pansy’s hardiness range in USDA zone 6, temperatures may plunge to minus 10 degrees F. Gardeners in cold climates such as this can trap heat in the soil and prevent freeze injury to pansies by simply applying a 2- to 4-inch-thick layer of pine straw mulch on top of plants.
What temperature do pansies die in?
As the air temperature dips below 25 degrees Fahrenheit, pansies flip into defense mode. Their green leaves may wilt and take on a grayish cast. But this doesn’t mean they are dying; it’s simply their natural response to below-freezing temperatures.
How to keep pansies from freezing?
Gardeners in cold climates such as this can trap heat in the soil and prevent freeze injury to pansies by simply applying a 2- to 4-inch-thick layer of pine straw mulch on top of plants. Pine straw is lightweight compared to heavy bark mulches, and it allows water to filter through and reach plants more easily than a heavy, compacted mulch.
Why do pansies die in pots?
Because the north-facing pansies could not absorb water through the frozen soil, they suffered dehydration and then death. This same principle applies to planting pansies in pots, which elevate the plants’ root balls above the protective insulation of the soil.
Can you mulch pansies?
In milder climates such as in the Deep South, mulch can be applied around the pansies in winter. And if a cold snap is predicted, gardeners can cover the pansies with lightweight frost-protection fabric until the hard freeze is over. But in climates where the soil may remain frozen for extended periods, it’s best to protect the plants with a solid mulch cover until the frozen soil thaws.
Can pansies survive the cold?
But even though they can survive sub-zero conditions, other factors come into play to determine whether pansies will die when subjected to temperatures that dip below 26 degrees Fahrenheit. It’s not just the air temperature but also the soil temperature that influences pansy survival during winter. And even the timing of applying fertilizer can weaken an otherwise healthy pansy plant and make it more susceptible to winter injury.
Do pansies grow in the summer?
Department of Agriculture plant hardiness zones 6 through 10, gardeners plant them in autumn to enjoy fall/winter or spring flowers (or both). Gardeners in these and other zones can also plant them in spring for flowers that last until the summer heat is too oppressive for them to continue to grow.
