Green onions, also known as scallions, are a staple of many vegetable gardens. They are easy to grow and used in many different recipes, from fresh salads to soups, casseroles and noodle dishes. Green onions have tiny bulbs, but the bulbs are so small they are difficult to save, even if the plant is left to die above the ground. Consequently, green onions are best grown from seed, and seed packets are readily available at garden centers, nurseries and home improvement stores.
Break up the ground with a trowel or garden fork, being careful to remove any rocks, stones, roots or other debris.
Mix in topsoil so that the top 3 inches of the ground are an even mixture of existing soil and top soil.
Drill half-inch-deep holes in the ground with your finger, in rows, 2 inches apart.
Place several seeds in each hole and cover with top soil. Gently pat down the ground and water promptly.
Watch the onion patch carefully and remove any weeds that might spring up and compete with your onions for nutrients. Green onion seedlings should emerge after a week or two, with the green onion plants ready for harvest as early as two months after planting.
