Red long-day onion for overwintering.

Robust, dark green plants survive winter well and produce red bulbs with deeper color than Desert Sunrise. Bulbs are round and uniform in size, maturing a few days behind Desert Sunrise when overwintered. In our trials, Red Spring is slightly more prone to bolting than Desert Sunrise when overwintered in Maine. Also a good option for a spring-sown, early red onion in long-day latitudes. Stores approx. 3 months.

Specs:

  • Packet: 250 seeds
  • Avg. 121,700 seeds/lb

Size

Packet, 1,000 Seeds, 5,000 Seeds, 25,000 Seeds, 100,000 Seeds

HARVEST

When necks become soft and 50% of tops are falling over, pull and cure in well-ventilated space out of direct sunlight (to prevent greening) or sun-cure in field for 2–7 dry days before moving to dry location. Cure until tops are completely dried; about 2 weeks.

SEED SPECS

SEEDS/LB.: 96,900–127,700 (avg. 112,000).

SIZED SEEDS

Standard on all varieties.

TRANSPLANTS

Avg. 1 oz./4,900 plants, 1 lb./78,750.

AVG. DIRECT SEEDING RATE

1 oz./25', 1M/50', 5M/250', 25M/1,250', 580M/acre at 20 seeds/ft., in rows 18" apart.

DAYS TO MATURITY

From direct seeding; subtract 10–15 days for days to maturity from transplant.

STORAGE

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

DISEASES

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

SCIENTIFIC NAME

Allium cepa

WATER

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

CULTIVATION

Keep onions well weeded with shallow cultivation.

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.

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.

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.

PACKET

250 seeds, sows 12' or makes 140 plants.
