What temperature can I plant pansies?
Also asked, what is the best time to plant winter pansies?
Ideally, plant your pansy seeds in borders or pots during September and early October – this will give them a better chance to grow sturdy roots and flowers.
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.
