Green Onions Scallions Cultivation Nutrition Uses and Economic Importance
Introduction
Green onions, commonly known as scallions or spring onions, are one of the most widely used vegetables in kitchens around the world. Recognizable by their long green hollow leaves and slender white bulbs with roots attached, green onions are prized for their mild flavor, versatility, and nutritional value. The image illustrates bunches of freshly harvested green onions, some with roots intact, highlighting different sizes and maturity levels commonly seen in local markets and farms.
Green onions belong to the Allium family, which also includes garlic, onions, leeks, and chives. Unlike bulb onions, green onions are harvested early before the bulb fully develops, allowing both the white base and green tops to be consumed.
Botanical Description
Green onions consist of three main parts:
- Roots – Thin, fibrous roots that absorb nutrients and water from the soil.
- White Stem (Pseudostem) – The edible base formed by overlapping leaf sheaths; mildly pungent and crisp.
- Green Leaves – Hollow, tender leaves with a fresh, grassy onion flavor.
The image shows onions at varying thicknesses, which indicates differences in soil fertility, spacing, and harvesting time.
Cultivation and Growing Conditions
Climate and Soil
Green onions grow best in:
- Cool to moderate climates
- Well-drained, fertile soil
- Soil pH between 6.0 and 7.0
They are fast-growing and suitable for both commercial farming and home gardens.
Planting
- Seeds or small onion sets are planted directly into the soil.
- Rows are spaced closely since large bulbs are not required.
- Germination usually occurs within 7–10 days.
Watering and Care
- Regular watering is essential, especially during dry periods.
- Excess water should be avoided to prevent root rot.
- Minimal fertilization is required, though nitrogen-rich soil encourages leafy growth.
Harvesting
Green onions can be harvested:
- 20–30 days for baby scallions
- 40–60 days for thicker stems
