Size Or Color When Ripe:
Pick green onions (scallions) when plants reach 6-8″ tall, while the stalks are still white at the bottom and fairly thin. When harvesting onion bulbs, about 100 days from sowing, bend the tops over when about ¼ of the tops have already fallen over and turned yellow. After a few days, pull the bulbs and cover them with the foliage to prevent sunburn. Allow onions to dry in the garden for up to a week, then cure them indoors in a warm, dry place with good air circulation for 2-3 weeks. Then cut off the foliage, leaving 1″ above the top of the bulb.
Days Until Maturity:
