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.
When can I put pansies outside?
WHEN TO PLANT PANSIES
Pansies can be planted in the early spring or the fall. Pansies can be finicky to start from seed; it’s a lot easier to buy established plants from a local nursery. Plus, you’ll get blooms a lot sooner.
Will pansies survive a frost?
Pansies and Violas are hardy plants and will survive a frost—and even a hard freeze—for a period of time. Depending on how hard the frost was, flowers that were blooming may wither, but the plants will stay alive.
Do pansies like sun or shade?
Light: Pansies do best with about six hours of sun daily. In warmest regions (Zone 7 and warmer), protect plants from full sun during the hottest part of the day. Too much heat can slow flower formation. New trailing pansy varieties, like Cool Wave, need a minimum of six hours of full sun to flower best.
What do you do with pansies 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.
How often do I water my pansies?
Pansies need 1 inch of water weekly when they are actively growing. However, gardeners need to ease up on watering when rain provides adequate irrigation. In addition, manual watering should occur in the morning so foliage has the morning sun and the rest of the day to dry.
Will pansies come back after a freeze?
Pansies bloom in the cold of winter, putting out new buds even as the other flowers freeze. They will sleep under the snow, and be ready to go again in the spring.
Do pansies come back every year?
The short, quick answer is, yes. Because they have little freeze tolerance, most will die in sustained winters. In areas with moderate temperatures, they may come again in spring, especially if they were mulched to protect the roots.
Can pansies tolerate heat?
Nothing will keep pansies happy in midsummer except being grown in an area where temperatures never rise above 70 degrees for more than a few days. While breeders continue to search for more heat-tolerant varieties, here is how to get the best pansy performance.
How long will pansies last?
That means if you plant them in the autumn, pansies can last up to eight months, from September to April or May, providing colorful blooms for much of that time. They usually aren’t very pretty in the dead of winter, but their spring blooms can be even more robust when the plants have been in the ground since fall.
Do pansy flowers spread?
Pansies like full or partial sun, but need cooler temperatures to thrive. The ideal planting site will get morning sun but avoid the heat of the late afternoon. Space the plants about 7 to 12 inches apart. They will spread about 9 to 12 inches and grow to be about 6 to 9 inches tall.
