SCARBOROUGH SEEDS Walla Walla Onions 125 Seeds

LATIN NAME: Allium cepa

DAYS TO MATURITY: Approx 300 late-summer sown and wintered over; 125 spring sown

LIFE CYCLE: Annual

HYBRID STATUS: Open Pollinated

The famous, mild yellow variety from Walla Walla, WA.

Juicy, sweet, regional favorite. In the Northwest, which has normal low winter temperatures above -10°F, seed is sown in late August, and a crop of very large, flattened, ultra-mild onions is harvested early the next summer. SPRING PLANTING: Walla Walla may be spring planted using seeds or plants in colder regions where winter survival is hit or miss. It is not as big or sweet as the wintered-over crop, but still milder and juicier than others from spring planting. Nice as a "green top" onion. Not for storage. 

Adaptation: 35-55° latitude.

CULTURE: Onions require full sun and fertile, well-drained soil with a pH of 6.0–7.0. Sandy loam soils are ideal; in heavier soils, use raised beds or raised rows to promote soil drainage.

 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.

 TRANSPLANTING: In short-season areas, sow seeds indoors in flats in late February to mid-March. Broadcast 1/2" apart and cover 1/4". Tops may be clipped to 5" tall. Transplant to the garden 4" apart, or sow 5 seeds in each cell of 1–1 1/2" diameter plug trays, thinning to 3 per cell. Transplant each cell 6" apart.

 CULTIVATION: Keep onions well weeded with shallow cultivation.

 WATER: Onions are shallow rooted and grow best with at least 1" per week of rain or irrigation, especially during the bulbing phase.

 DISEASES: Adequate air circulation and crop rotation aids in reducing the risk of foliar disease.

 HARVEST: When necks become soft and tops are falling over, pull and sun-cure at least 2–7 days, depending on weather. Move to a protected location to finish drying.

 STORAGE: When dry, clip off tops and roots and store in onion bags or shallow boxes at near freezing and 65–70% humidity.

DAY LENGTH: Onion bulbing is triggered by day length, and maximum day length during the growing season increases from south to north. Intermediate and long-day onions are grown at higher latitudes. Refer to "Adaptation" for details.
