How to Grow Pansy
Annual
Pansies (Viola x wittrockiana) are cool-season flowers prized for their broad, flat blooms and cheerful face-like markings in nearly every color. US home gardeners grow them because they tolerate frost and light freezes, filling beds and containers with color when little else is flowering. Most gardeners treat them as annuals, planting in fall or early spring for a burst of bloom during the cooler months.
Planting
Set out transplants in early spring a few weeks before the last frost, or in fall about six to eight weeks before the first hard freeze so roots establish while the soil is still warm. Choose a spot with full sun to part shade and moist, well-drained soil rich in organic matter, and space plants about 6 to 9 inches apart so they knit together as they grow. To start from seed, sow indoors roughly 10 to 12 weeks before your target planting date, since seedlings develop slowly and germinate best in cool, dark conditions. Pansies handle cold well, so there is no need to wait for warm weather to plant them out.
Care
Keep the soil consistently moist but not soggy, watering at the base to keep the leaves and flowers dry and reduce disease. Feed lightly during active growth with a balanced garden fertilizer, following the directions on the package, since cool soils can slow nutrient uptake. Pinch or snip off spent blooms regularly to keep plants tidy and encourage more flowers rather than seed set. As summer heat arrives, plants stretch and decline, so shear leggy growth or replace them, and in mild-winter regions a layer of mulch helps fall plantings survive the cold.
Bloom time
Pansies bloom heavily through the cool weeks of spring and fall, and in mild-winter areas they can flower on and off all winter. Flowering slows and stops once summer heat sets in.
Garden uses
They shine in beds, borders, edging, window boxes, and mixed containers where their low, mounding habit fills the front of a planting. The blooms also make charming, if short, cut flowers and are a welcome early nectar source for pollinators.
Tips
Buy compact, stocky transplants with plenty of buds rather than plants already stretched and in full bloom, since younger plants establish and perform better. Deadhead often and water steadily to extend the flowering season, and avoid crowding to keep air moving and foliage healthy. In hot-summer regions, plan on pansies as a temporary display and swap them for heat-loving flowers once they fade.
