When planting onion seeds, place them at 1/2-inch intervals, and cover them with an inch of soil. Once the seeds sprout, thin them to 4- to 6-inch intervals that allow room for the bulbs to grow to maturity. If you plant onion sets, which are seeds that have sprouted into plants approximately 4 inches tall, space them using the larger spacing, eliminating the need to thin plants later.

Prepare the planting beds for onions by working 2 to 4 inches of well-rotted manure or compost along with up to 2 pounds of complete fertilizer per 100 square feet into the soil.
