Evergreen Long White Bunching Onion Seeds

Sowing: Since most onions take a few months to mature from seed, gardeners with a short growing season may want to start their green onion seed indoors. Plant the seeds approximately 1 centimeter deep in a flat 5-7 centimeters before the last frost date; keep the soil moist and at room temperature (approximately 20-25 degrees Celsius). When the tops begin to flop over, cut them off to approximately 8 centimeters to focus the growing on the roots. Four weeks before the last frost or when the soil reaches at least 10 degrees Celsius, transplant the seedlings approximately 8 centimeters apart in rows 30.5 centimeters apart. For direct sowing, sow three seeds per 2.54 centimeters 1 centimeter deep in light, rich soil and full sun. Thin the seedlings approximately 8 centimeters apart. Thinned onions can be transplanted or used for fresh eating. For companion planting benefits, plant onions with members of the cabbage family, lettuce, or tomatoes; avoid planting onions with peas or beans.

Growing: Onions need moisture especially in their first several weeks of growth, and they cannot fight against weeds; mulching onions can help with both moisture and weed control. Evergreen White Bunching onions tolerate cold and light frost, since they are the most cold hardy bunching onion available. Green onion seeds are slow to bolt and resistant to PR, thrips, and smut.

Bunching onions can be harvested as early as 60 days after planting, with the flavor intensifying the longer they are left in the ground. When adequately protected from cold weather, these green onion plants can survive the winter months and be harvested in spring for bunching. While versatile for use as both green onions and scallions, this onion variety does not store well for extended periods.

To ensure onion seed production, it's necessary for onions to survive through winter. In regions with milder climates, a thick layer of mulch suffices, which can be removed in early spring. However, in areas experiencing very cold winters, onions should be pulled up with half the stem cut off. These onions are then stored in a dry place at temperatures between 32-40 degrees Fahrenheit until spring for replanting.

Before replanting, it's recommended to cut an X shape at the top of the onion to facilitate stalk emergence. As the green onion plants flower and produce seeds, it's important to remove the seed heads carefully once the seeds become visible, ensuring they are not lost. The seed heads should then be spread out in a well-ventilated, dry area and left to dry for several weeks. After drying, the green onion seeds can be threshed out and stored in a cool, dry place for up to two years.
