Onion Seeds - Walla Walla Sweet

Walla Walla onions are a distinctive, sweet onion variety renowned for their large size, mild flavor, and delicate texture. Their bulbs are typically round or slightly flattened, with smooth, pale yellow to light brown skins, and their flesh is exceptionally sweet and mild, making them ideal for raw consumption in salads, salsas, or on sandwiches. Known for their low sulfur content, which contributes to their sweetness, Walla Walla onions are a long-season crop, requiring a full growing cycle to reach maturity. They are beloved by gardeners for their ability to grow in a variety of climates, though they flourish best in well-drained, fertile soil with ample sunlight.

Onion bulbing is triggered by day length, and maximum day length during the growing season increases from south to north. Short-day onions are grown at lower latitudes in the South, while intermediate and long-day onions are grown at higher latitudes. Refer to "Adaptation" in each variety description for details.

TRANSPLANTING:
In long- and intermediate-day areas, sow indoors 6–8 weeks before last frost date. Sow 128-cell trays, 1 seed/cell, and cover with 1/4" soil. Transplant 4" apart in rows 12–18" apart. Unruly tops may be clipped to 5" at time of transplant.
DIRECT SEEDING:
In April or early May, or as soon as the soil can be prepared in early spring, sow in a 2" wide band, about 2 seeds/in., 1/4– 1/2" deep, rows 12–18" apart. Thin to 1 1/2–2" apart for highest yields in fertile soil. Thin to 3-4" apart for larger onions.
