The pink-hued bulbs of Blush Onion deliver visual interest alongside reliable harvests. At just 2 inches of spacing and a mature width of 24 inches, it grows compactly enough for containers or tight garden rows. With 110 days from transplants and frost-hardy vigor, this hybrid produces consistent yields even for gardeners in cooler zones, reaching from zone 3 northward through zone 10.
Blush Onion serves as a dual-purpose crop: the bulbs store well for kitchen use throughout the season, while younger plants can be harvested as scallions when pencil-sized or larger. Its pink color makes it particularly valued for fresh eating and garnishes where visual appeal matters, from salads to cooked dishes where the color persists.
Start seeds indoors 6 to 8 weeks before your last frost date in 128-cell seed trays, sowing 1 seed per cell and covering with 1/4 inch of soil. Maintain a germination temperature between 70 and 90°F. If seedling tops reach more than 5 inches before transplanting, clip them back to 3 to 5 inches to encourage stockier growth.
Transplant seedlings 4 inches apart into rows spaced 12 to 18 inches apart once they've hardened off and the soil is workable in spring. Carefully separate seedlings and place them in a shallow trench, then fill around them and water in well. In long- and intermediate-day growing regions, transplanting after the last frost date ensures optimal bulb development.
For direct sowing, thin seedlings to the strongest plant when they reach 4 to 5 inches tall.
Harvest Blush Onion when approximately half the tops have fallen naturally and turned brown. After pushing over any remaining upright foliage, wait about 1 week before lifting bulbs from loosened soil. Always harvest in dry weather, as onions picked in wet conditions do not cure properly and are prone to rot. Remove any plants that have sent up flower stalks, as these bulbs will not store well.
Once bulbs begin approaching maturity and about half the tops have naturally fallen over, push the remainder to the ground to halt foliage growth and direct energy into final bulb development. Wait approximately 1 week after this step before harvesting. Loosen the soil around bulbs gently to encourage faster drying.
