They can be planted close together for a unique, red pearl onion, or spaced farther apart for a zippy, full-sized cipollini that is quite the rage amongst the culinary crowd.
Plant the seeds 1/2" 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 6" apart in rows 12" apart.
For direct sowing, sow three seeds per inch 1/2" deep in light, rich soil and full sun. Thin the seedlings 2-6" apart, depending on the desired size. Thinned onions can be transplanted or used for fresh eating.
