Onions have a shallow root system and are adapted for well drained, rich, loam-type soil. Either start seeds indoors, or directly into the garden, in a sunny location, from April to mid-July.
Plant onion seeds ½ inch deep, two to four seeds per inch in rows spaced twelve to sixteen inches apart. Thin the plants to four inches apart to allow the bulbs room to develop. Use thinnings as green onions.
