To grow green onions successfully, follow these key steps: Planting

• You can start green onions from seeds indoors about 8-10 weeks before the last frost or plant them directly outdoors in mid-spring when the ground is workable and frost risk has passed

• Sow seeds 1/4 to 1/2 inch deep in well-draining, fertile soil with a slightly acidic to neutral pH. Space rows 12 to 18 inches apart and thin seedlings to about one per inch once they emerge

• Alternatively, regrow green onions from store-bought scraps by placing the root ends in water on a sunny windowsill until green shoots appear, then transplanting into soil for better growth

Growing Conditions

• Choose a location with at least 8 hours of direct sunlight daily for optimal growth

• Green onions prefer soil rich in organic matter like compost and require consistent moisture-about 1 inch of water weekly-but avoid waterlogging to prevent root rot

• Ideal temperature range is 55 to 75°F; avoid extreme heat or frost

Care

• Fertilize soil before planting with a balanced fertilizer (e.g., 10-10-10) and sidedress with fertilizer 4-5 weeks after planting

• Mulch around seedlings to retain moisture, regulate soil temperature, and suppress weeds

• Water regularly, especially if growing in containers, which dry out faster

Harvesting

• Harvest when stems are 1/4 to 3/4 inch thick by pulling the entire bulb or cutting green tops to allow regrowth

• Green onions can be harvested repeatedly by cutting leaves near the base, encouraging continual growth

Pest Management

• Watch for common pests like aphids, thrips, cutworms, and leaf miners; proper spacing, good soil, and avoiding heavy rain exposure help reduce pest issues

By following these guidelines, you can grow green onions easily in your garden or even indoors in containers or on a windowsill, ensuring a fresh, renewable supply
