About Evergreen White Bunching Onion: Most likely coming from Asia, this unusual onion has a different name in nearly every country that cultivates it; spring onions, Japanese onions, Welsh onions, scallions, green onions to name only a few. The countries of eastern Asia remain on the top of the list for bunching onion production.
Evergreen White Bunching Onion Germination: Since most onions take a few months to mature from seed, gardeners with a short growing season may want to start their seed indoors. Plant the seeds 1/4" deep in a flat 2-3 months before the last frost date; keep the soil moist and at room temperature. When the tops begin to flop over, cut them off to 3" to focus the growing on the roots. Four weeks before the last frost or when the soil reaches at least 50 degrees F, transplant the seedlings 3" apart in rows 12" apart. For direct sowing, sow three seeds per inch 1/4" deep in light, rich soil and full sun. Thin the seedlings 3" 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 Evergreen White Bunching Onion Seeds: 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. They are also slow to bolt and resistant to PR, thrips and smut.
Harvesting Evergreen White Bunching Onion: Bunching onions can be harvested any time after 60 days; the longer they remain in the ground, the stronger the taste will be. If protected sufficiently from the cold, the plants will overwinter for spring bunching. This variety of onion can be used for both green onions and scallions, but does not store well long term.
Saving Evergreen White Bunching Onion Seeds: Onions need to overwinter before producing seed. In warmer locations, simply apply a thick layer of mulch and remove it in the early spring. In areas with very cold winters, pull up the onions and cut off half the stem; store them at 32-40 degrees F in a dry place until spring, when they can be replanted. Before planting, cut an X in the top of the onion to allow the stalk to emerge. The plants will flower and go to seed. Remove the seed heads when the seeds become visible, taking care not to shatter the heads and lose the seed. Spread the heads out in a dry place with good ventilation, and let them dry for several weeks. Thresh out the seeds and store them in a cool, dry place for up to 2 years.
