Large, flattened globe bulbs can be harvested in August from spring sowings for short-term storage. In areas with normal low winter temperatures above -10°F (-23°C), seeds sown in August can be harvested early the next summer. In colder areas, it can be planted in the fall and covered with row cover and Quick Hoops™. Adaption: 35-45° latitude. Also available pelleted. Avg. 104,400 seeds/lb. Packet: 250 seeds.

Shipping Information & Notes
CULTURE: Onions require full sun and fertile, well-drained soil with a pH of 6.0-7.0. Sandy loam soils are ideal; raised beds or raised rows are recommended for heavier soils 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. 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. DAYS TO MATURITY: From direct seeding; subtract 10-15 days if transplants are used. AVG. DIRECT SEEDING RATE: 1 oz./25', 1M/50', 5M/250', 25M/1,250', 580M/acre @ 20 seeds/ft., in rows 18" apart. TRANSPLANTS: Avg. 1 oz./4,900 plants, 1 lb./78,750. SIZED SEEDS: Standard on all varieties. SEED SPECS: SEEDS/LB.: 96,900-127,700 (avg. 112,000). PACKET: 250 seeds, sows 12' or makes 140 plants.
