They grow best when soil temperatures are between 45°F and 65°F (7°C and 18°C). Pansies can tolerate a light frost just after planting, but try to hold off on putting them in the ground if temperatures are still regularly reaching well below freezing.

Additionally, how hardy are pansies? Pansies are hardy winter flowers that tolerate cold snaps in Mediterranean climates of U.S. Department of Agriculture plant hardiness zones 8 to 10, as well as light snowfalls in USDA zones 4 to 7.

Accordingly, where should I plant pansies in my yard?

Pansies perform best in cooler weather, and are therefore usually planted in spring or fall. They like rich, well-drained soil high in organic matter, and full sun or partial shade. (Shade is especially beneficial south of Zone 7 where the hot afternoon sun will shut down flower production.)

Pansies are cool-weather biennials that are frost-hardy when dormant. Pansy roots can survive winter temperatures as low as minus 25 degrees under the soil. Actively growing seedlings can withstand light frost, but a deep freeze will kill the foliage.

Is it too early to plant pansies?

When to Plant
For best results, plant pansies when the soil temperature is between 45 and 65 degrees. But if you plant too early — when the soil is above 65 degrees — you'll wind up with leggy plants, yellowish leaves and few flowers. Pansies planted then are also more susceptible to frost.

How far apart should you plant pansies?

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.

How long will pansies last?

Many gardeners chafe at the idea of splurging for flowers that may not last more than a month in the ground. However, if planted in fall, pansies can last up to eight months, from September to April or May, providing fall and spring color. That's a pretty good deal.

Is it OK to plant flowers now?

The hardiest of flowers can be planted as soon as the soil in your garden can be worked, even if it's several weeks before the last frost of the season. For half-hardy flowers, hold off until a couple weeks before the final frost, and for tender flowers, plant when there's no chance of frost for the rest of the season.

Do pansies come back year after year?

There are no true perennial pansies that return year after year and flower. If you have pansies that act like perennials, they're actually re-seeding annuals and biennials. Annual and biennial pansies can act like perennial pansies in consistently warm climates, such as those in zones 9 to 11.

How do you keep pansies from getting leggy?

Cut leggy pansies back to 5 to 7 inches tall. Make each cut right above a leaf set on the stalk. Use a pair of small clippers to cut the delicate stems. After cutting back pansies, apply 1 teaspoon of fertilizer per square foot of garden bed.

Why are my pansies drooping?

Fungus growing in wet, poorly drained soil can result in root or crown rot, which causes the roots of the pansies to rot and leads to a wilted, drooping plant. Watering early in the day, so the excess moisture has time to evaporate, can also prevent rot.

How many hours of sunlight do pansies need?

Full sunlight is characterized as six to eight hours. Partial light is from three to six hours and shade is three or less hours of sunlight. Pansies enjoy direct sunlight, especially in the winter months because it allows them to warm up. Likewise, flowers planted in shaded locations will produce fewer blooms.
