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.

Life Cycle
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

Hybrid Status
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits.

Walla Walla Sweet Onion Seed
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 (-23°C), 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. Also offered organic, and as plants.Specs:

SCIENTIFIC NAME:
Allium cepaCULTURE:
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" in each variety description for details.DAYS TO MATURITY:
From direct seeding; subtract 10–15 days for days to maturity from transplant. 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.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.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:
