Planting Guide A large, sweet yellow onion. Loved for its mild, sweet flavor. Excellent raw. It does well in Western states and similar climates. It has fair storage characteristics. Intermediate day. Start seed indoors in early spring for summer harvest in the north. Begin them in flats 8 weeks before expected transplant into the garden. Space seedlings 2 to 3 inches apart in the garden. If you want crisp, tender green onions, harvest the bulbs just after the swelling begins. For mature bulbs, wait until the tops fall over after the growing season. Then dig up the bulbs, cure for 3 weeks, and store in a cool, dry place.
