Step-by-Step Guide: Grow Onion Greens in 7 Days
Follow these simple steps to enjoy fresh onion greens within a week:
Step 1: Choose the Right Onions
- For fastest growth, select small to medium-sized onion bulbs.
- You can use store-bought onions if they are healthy and firm, preferably with the root base intact.
- Alternatively, green onion seeds can also be used, though bulbs sprout faster.
Step 2: Prepare the Container
- Use shallow trays, small pots, or even recycled containers with drainage holes.
- Fill with nutrient-rich soil or cocopeat, leaving 1–2 inches from the top.
- Lightly moisten the soil to prepare it for planting.
Step 3: Plant the Bulbs or Seeds
- Bulbs: Place them root side down, spacing 2–3 cm apart.
- Seeds: Sprinkle evenly on the surface and cover lightly with a thin layer of soil.
- Press gently to ensure good contact between soil and roots.
Step 4: Provide the Right Sunlight
Onion greens need 4–6 hours of sunlight daily.
- Place the container near a sunny window, balcony, or terrace.
- If indoors, use grow lights for 6–8 hours per day.
- Avoid extreme heat or direct scorching sun as it may dry the soil quickly.
Step 5: Watering and Moisture
- Keep the soil consistently moist but not waterlogged.
- Use a spray bottle to mist the soil lightly each day.
- Moisture is key for fast sprouting—dry soil slows down growth.
Step 6: Watch for Sprouts
- Within 2–3 days, you’ll see tiny green shoots emerging.
- By day 5, the shoots will be 4–6 cm long.
- By day 7, your onion greens are ready for harvest!
Step 7: Harvesting Onion Greens
- Use scissors to cut the greens 1–2 cm above the soil.
- Do not pull out the bulbs; leaving them in the soil allows for continuous regrowth.
- Harvest every few days to maintain fresh growth.
Tips to Boost Growth and Yield
- Use nutrient-rich soil: Add compost or vermicompost for faster growth.
- Regular watering: Keep soil moist to prevent stunted growth.
- Partial shade in summer: Protect greens from scorching sun.
- Rotate containers: For uniform sunlight exposure, rotate trays daily.
- Fertilize lightly: Use diluted organic liquid fertilizer once a week for lush green leaves.
Common Problems and How to Fix Them
1. Slow Growth
- Cause: Lack of sunlight or poor soil
- Fix: Move container to a sunnier spot and add compost
2. Yellowing Leaves
- Cause: Overwatering or nutrient deficiency
- Fix: Reduce watering and apply mild organic fertilizer
3. Pests
- Cause: Aphids or mites
- Fix: Spray neem solution or use soap-water mix
4. Dry or Wilted Tips
- Cause: Low humidity or water stress
