How to Grow Green Onion Plant Outdoors

Green onion, also known as scallion or spring onion, is a versatile vegetable that can be used in various dishes. It has a mild onion flavor and is commonly used in salads, soups, stir-fries, and other culinary creations. Growing your own green onion plant can be an enjoyable and rewarding experience. In this article, we will guide you through the steps of growing green onion plant outdoors.

Choosing the Right Location

Green onion prefers well-drained soil with full sun exposure. It can also tolerate partial shade but may grow slower. Before planting, choose a location that receives at least six hours of sunlight per day. It is best to avoid areas that are prone to flooding or have poor drainage.

Preparing the Soil

Green onion prefers loose soil that is rich in organic matter. To prepare the soil, loosen it by tilling or digging to a depth of at least 6 inches. Remove any rocks, weeds, or debris that may impede growth. Mix in compost or well-rotted manure to enrich the soil and improve drainage.

Planting the Green Onion Bulbs

Green onion can be grown from seeds or bulbs. Bulbs are the easier option for beginners as they require less time to mature. To plant the bulbs, make shallow trenches about 1 inch deep and 4 inches apart. Place the bulbs at the bottom of the trench with the pointed side facing upwards. Cover with soil and water thoroughly.

Watering and Fertilizing

Green onion requires regular watering to keep the soil moist but not waterlogged. Water deeply once a week or more frequently during hot and dry weather. Avoid overhead watering as it can increase the risk of disease. Fertilize every four to six weeks with a balanced fertilizer or compost tea.

Maintaining the Green Onion Plant

Green onion needs little maintenance once established. Keep the area around the plants weed-free to avoid competition for nutrients. Mulch with straw or grass clippings to retain moisture and suppress weed growth. If the green onion plant starts to flower, cut off the flower stalk to redirect energy towards bulb growth.

Harvesting Green Onion

Green onion can be harvested when the plants reach 6 to 8 inches tall. Gently pull the plants out of the soil or use a sharp knife or scissors to cut them at the base. Avoid yanking or twisting the plants as it can damage the roots. Store the harvested green onion in a plastic bag in the refrigerator for up to a week.

Troubleshooting Common Problems

Pests

Green onion is relatively pest-resistant, but it may attract aphids, thrips, or onion maggots. To control them, use insecticidal soap or neem oil spray. Alternatively, introduce natural predators such as ladybugs or lacewings.

Diseases

Green onion is vulnerable to fungal diseases such as powdery mildew, downy mildew, and fusarium wilt. To prevent them, avoid overhead watering and overcrowding, and space the plants properly. Remove any infected leaves or plants and dispose of them away from your garden.

Bolting

Bolting is when the green onion plant starts to produce flowers prematurely. It is caused by stress factors such as heat, cold, drought, overcrowding, or insufficient nutrients. To prevent bolting, provide adequate water and nutrients, and thin out the plants if necessary.

Conclusion

Growing green onion plant outdoors is an easy and rewarding activity that can yield a fresh supply of this versatile vegetable. By following these simple steps and troubleshooting common problems, you can enjoy a bountiful harvest of green onion in your own backyard.
