    Sow seeds in early spring as soon as soil can be worked; in mild winter areas, seeds can also be sown in fall to overwinter for a head start in spring growth. They have a broad planting range, being on the cusp of intermediate and long day onions.

    To Start Early Indoors: Sow 1 in. apart in a container of seed starting mix and cover 1/4 in. deep. Provide a strong light source until seedlings are 2 to 3 in. tall. Transplant 4 in. apart, burying crowns 1 in. deep.

    To Start Outdoors: Sow seeds in well-worked, fertile soil in full sun. Space 1 in. apart in rows 8 in. apart. Cover 1/4 in. deep, firm soil well over seeds, and keep evenly moist. Thin seedlings gradually to a final 4 in. spacing, using the tasty thinnings.

    GROWING NOTES

    Before planting, thoroughly work compost or well-aged manure and an organic, all-purpose fertilizer into the soil. Keep onions well-weeded and mulch plants once soil warms up to conserve moisture. Feed onions lightly with an all-purpose fertilizer several times during the growing season. The “bite” or spiciness of onions depends on your soil type and composition.

    HARVEST AND USE

    Harvest midsummer when bulbs are sized up and about half the onion tops are bent over. Stop watering and bend the rest of the tops down. After another 7 to 10 days or when tops are dry, pull the bulbs. If possible, let the onions dry in the sun for 5 to 7 days. Store bulbs in a cool, airy place.

    GROWING NOTES

    Before planting, thoroughly work compost or well-aged manure and bone meal into the soil. It is critical to weed onions carefully and mulch once soil warms up to conserve moisture. Side dress lightly several times during the growing season with a general purpose fertilizer; stop fertilizing during the last 2 months of growth.


    HARVEST AND USE

    Harvest bulbs about midsummer when bulbs are sized up and about half the onion tops are bent over. Stop watering and bend the rest down and lay in the sun for another 7 to 10 days or until tops dry. Store in a cool, airy place. Use soon as these heirlooms are not known as long keepers.
