Days To Maturity
Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

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.
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 range in onion type headings for more details.
Days to Maturity: From direct seeding; subtract 10–15 days for days to maturity from transplant.
Transplanting: Long- and intermediate-day onions: Sow indoors 6–8 weeks before last frost date. Sow into 128-cell trays, 1 seed/cell, or sow into 1 1/2" plug trays, 3 seeds per cell. Cover with 1/4" soil. Transplant 4–6" apart in rows 12–18" apart. Unruly tops may be clipped to 5" at time of transplant. Short-day onions: Sow indoors in early September, 6–8 weeks before you plan to transplant. Sow as above for long- and intermediate-day onions. Alternately, direct-sow seeds into a dedicated "seedling" bed: sow seeds 1/4" apart in rows 6" apart. At 4–6 weeks, gently lift seedlings and transplant to final location. If nights will fall below 50°F (10°C), cover transplants with medium-weight row cover to protect young seedlings from cold damage and to warm the soil for optimal establishment. Remove row cover when nights are consistently over 50°F (10°C).
Direct Seeding: In long- and intermediate-day areas, sow in April or early May, or as soon as the soil can be prepared in early spring. In short-day areas, sow in early September. 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.
Avg. Direct Seeding Rate: 1 oz./25', 1M/50', 5M/250', 25M/1,250', 580M/acre at 20 seeds/ft., in rows 18" apart.
Crop Maintenance: Keep onions well weeded with shallow cultivation. Onions are shallow-rooted and grow best with at least 1" per week of rain or irrigation, especially during the bulbing phase.
Disease: Adequate air circulation and crop rotation aids in reducing the risk of foliar disease. All Johnny's onion plants are tested and certified free from the presence of white rot and parasitic nematodes.
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. Short-day onions can also be treated like "spring onions" or "bunching onions," which are young, fresh onions that are harvested with green tops and immature bulbs and sold in bunches for a fresh, mild flavor and edible tops.
Storage: When dry, clip off tops and roots and store in onion bags or shallow boxes at near freezing and 65–70% humidity.
Transplants: Avg. 1 oz./4,900 plants, 1 lb./78,750.
Sized Seeds: Standard on all varieties.
Seeds/Lb.: 96,900–127,700 (avg. 112,000).
Packet: 250 seeds, sows 12' or makes 140 plants.
