This nineteenth century variety derives its name from Wethersfield, Connecticut, where it is said to have originated. This onion forms a large, flattened bulb five inches in diameter with purplish-white flesh. Sow seed one-quarter inch deep in early spring or late summer, and thin to three to four inches apart. Plant in deep garden loam in full sun. It is very strong flavored and a good keeper. It is hard to find! They are planted in gardens in late fall or early spring and in 4 to 5 weeks you will have green onions. If left to fully mature you will have dry onions in late July or early August. 100 days from transplant. Easy to grow with a long storage life. Make sure your are planting in an undisturbed location with fertile soil since they have shallow root systems. Use a straw mulch to retain moisture. Keep an eye on the green shoots. Keep weeded and regularly watered to help ward off pests. Long day type, grows well in northern climates. A reliable keeper grown since at least 1843. Planting Depth: 1/4 - 1/2" . Soil Temp. for Germination: 50-85 degrees. Days to Germination: 7-14. Plant Spacing After Thinning: 4-6". Days to Maturity: 110-115. Keep entire seedbed moist throughout germination.Soil & Water: Enrich soil with compost. Onions need at least 1 inch of water per week to develop sizable bulbs. Harvesting & Seed Storage: Harvest when green tops begin to fall over. Cure in a warm, dry, well ventilated area until tops are completely dry. Cut tops and store in a cool area. Store seeds in cool, dry, dark conditions. For storage longer than 2 years, place in freezer.
