Onion Seed

An Onion a day keeps the doctor away! A millenial food source, Onions have antioxidant, anticancer, anti-cholestrol and anti-inflammatory properties as well as being one of the mirepoix triad, a flavor base in most savory recipes. Although they are cool-weather lovers, Onion seeds are best sown indoors, 2 to 4 weeks before the last spring frost date. They may also be direct-sown after all threat of frost has passed. Water regularly until the end of their growing season, then hold back when the tops begin to brown. When the Onion greens have toppled over, gently pull them out and leave them on top of the soil, weather permitting, to cure for a couple of days. Deer resistant.

Average seed life: 2 years.

100-110 days. For something out of the ordinary in the Onion department, try these bronze-rose Cippolini - little Onions! Borettana is an Italian heirloom maturing to 2" in diameter and 1" thick. It resembles a flattened button and the fine, firm flesh and unique flavor is perfect for the gourmet gardener. The attractive bronze color of Borettana Cippolini lends itself to sautéing until slightly caramelized as an accompaniment for meats, fish or chicken. (OP.)

Days to Germination: 5-12 days
Germination Temperature:45°-75°F

Direct sow as soon as the soil can be worked. To raise Onions from transplants, sow seed in flats ½” apart. Provide warmth, ventilation and even moisture. Prepare the Onion bed in full sun with organic fertilizer, well-rotted manure and/or compost. Transplant the tiny seedlings when the danger of frost has passed, planting rather shallowly, with as little root disturbance as possible. Water Onions regularly and feed as needed with kelp or fish emulsion. Toward the end of their growing cycle, begin to hold back on watering. When most of the Onion greens have fallen over, stop watering for 1 week. Then, gently pull out the Onions and leave them on top of the dry soil for a couple of days, if weather permits. For “scallion”-type of Onions, harvest by pulling gently at the base of the greens, when the desired size has been reached (the smaller the better).
