SCIENTIFIC NAME: Allium cepa
CULTURE: Sow in early spring in 2-4" wide bands or single rows 4" apart, about 1/2" between seeds. Cover 1/4- 1/2". Thinning is not necessary. Keep free of weeds. As with all onions, full sun, consistent soil moisture, and a fertile soil with a pH of 6.2-6.8 are preferable.
HARVEST: Pull by the bunch whenever needed. No skin forms until 2-3 months into the season, making mini onions easy to wash and prepare.
ADAPTATION: Mini onions are smaller and earlier to bulb the further north they are grown. Suited to 40° and higher latitudes for pearl and cipollini onions, for small to medium onions at lower latitudes.
AVG. DIRECT SEEDING RATE: 5M/50', 1 oz./80', 13 oz./1,000', 34 lb./acre at 96 seeds/ft. in 4" wide bands, in rows 12" apart.
