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.
But if you want to seed, start pansy seeds indoors in late winter 8 to 10 weeks before the last spring frost for early spring and summer flowering. Or, start seeds in late summer for fall and winter flowering. Pansy seeds may be slow to germinate (typically emerging in anywhere from 1 to 3 weeks, depending on soil temperature).
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).
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.
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.
Pansies in Pots
Pansies are great for containers. Just use potting soil.
Plant in portable containers (12 inches or less in diameter) so the plants can be moved to a cooler area when the sun starts to get stronger. Early in the spring season or in the fall, a south-facing patio might be the perfect spot. During the summer, move pansies to the east side of your home for morning sun and afternoon shade.
