Because sweet white Spanish onions take a few months to mature from seed, gardeners with a short growing season will need to start the seeds inside. 2-3 months before the last frost date; Plant the seeds 1/2" deep in a flat, keep them at room temperature and moist . When the tops fall over, trim to 3" or 4" to focus the growing on the roots. Four weeks before the last frost or when the garden soil reaches 55 F, transplant the seedlings 4" to 6" apart in rows . To direct sow, sow three seeds per inch 1/2" deep in full sun, and light, rich soil. Thin the seedlings 2-6" apart. Thinned onions can be used for fresh eating or transplanted. Plant onions with cabbage family members, lettuce, or tomatoes; avoid planting onions with peas or beans. Long-day onions may be grown as a winter or fall crop in areas with warmer winters.
