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.

Yellow Granex Sweet Onion

Yellow Granex Sweet Onion Yellow Granex Sweet Onion Yellow Granex Sweet Onion
150 days. Originally made famous by the Vidalia Onion growers in Georgia, Yellow Granex is arguably the sweetest Onion ever grown. A thick, yellow-skinned, globe-shaped Onion, it has an incredibly mild, sweet flavor. A few tips for northern gardeners: plant Yellow Granex early (by mid-April) and provide consistent moisture. Its degree of sweetness or pungency will vary depending on your climate and garden soil. Used in salads and sandwiches, they are 'short-keepers'. We love caramelized Yellow Granex Onions so much that we prepare batch after batch, and freeze them in thin layers in airtight plastic bags. Then, we can break off pieces for quick and delicious use in Sunday morning omelets, mushroom-Madeira reduction sauces and baguette boat sandwiches layered with Basil mayonnaise, roasted Eggplant and Zucchini, Tomatoes and provolone cheese, sizzled under the broiler. But our favorite use is in chicken rollups. Pound boneless chicken breasts to about 1/8" thick. Spread each breast with a mixture of sauteed Garlic, caramelized Yellow Granex and wilted Spinach. Top with thin strips of roasted red Peppers and dollops of soft herbed goat cheese. Roll them up, secure with a toothpick and bake covered for 35 to 45 minutes at 350°F in a bath of herbed chicken broth, turning occasionally. Serve piping hot topped with fresh Parmesan on a bed of wild rice alongside glazed baby Carrots and homemade cranberry compote. (F1.)

Onion Sowing Instructions
Planting Depth
Row Spacing:12”
Seed Spacing:1”-3”
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).
