Botanical Name: Allium cepa
Sowing Season: Winter.
Sowing method: Transplantation.
Because the seeds are small in size, Green Onion plant is grown by transplantation method. Seeds are first sown indoors in seedling trays or outdoors on seed beds & later the seedlings are transplanted into the container or in raised beds.
Sowing container: Seedling trays/ seed cups/ small polybags/ Seed bed.
Sowing medium: Coco peat (indoors), Fine soil (outdoors)
Steps for seed sowing (Seed starting) in a container:
Covering: Keep the seed tray in a box or cover it with paper for first 4-5 days to encourage faster seed germination.
Growth stages of Green Onion Plant:Sprouting Stage: Seeds will germinate within first 6-8 days & tiny sprouts will be visible. Once seeds germinate, put the tray on an open partially sunny spot near the window. Don’t cover the tray anymore.
Cotyledons: The first two leaves will emerge in the second week of germination. These are false leaves called as cotyledons.
First leaves: First leaves will emerge above cotyledons at the end of the second week.
Seedling stage: Second week onwards, seedlings will start growing into a small plant. At this stage exposé the seedlings to more & more sunlight for leaf growth.
Thinning: After the second week, keep only single seedling per cell/cup. Cut off the weak, small & lagging seedlings with a pair of scissors.
Transplantation: 25 to 30 days after the seed sowing, your seedlings will be ready to transplant in container pots or raised beds.
Spacing: Plant the seedlings minimum 1X1 foot apart from each other on raised beds or in a container.
How to take care for Green Onion Plant:Sunlight: Green Onion grows well under full sunlight in winter. So place your containers accordingly.
Watering: Water your potted Green Onion plant every alternate day in winter. Water at the soil near the plant. Use a watering can and make sure that the plants get water in the form of the shower & not by a single flow. You can also make provision for watering by watering by drip irrigation system for your raised beds. Avoid overwatering.
Note: Stop watering green onion plants 2 weeks before harvesting if you are growing them for only bulbs.
Manuring: Add good quality organic manure in the soil with 2:1 ratio before transplanting the seedling. Organic fertilizer can be well rotten cow dung manure, farmyard manure, compost or Vermicompost.
Top Dressing: Apply balanced liquid fertiliser or handful of vermicompost to each plant, every 15 days after transplantation.
Plant care: Always look for the early signs of any insect/fungal/ any other infections. Spray appropriate medicines as soon as any symptoms of such diseases are spotted. Watch out for snails & slugs.
Harvesting: (90-100 days from seed sowing)
60 to 65 days after transplantation, Green onion bulbs will be ready to harvest. Harvest the onion bulbs along with leaves while bulbs are still young. If you want only bigger onions without leaves, wait for 20 more days (no watering) before harvesting so that bulbs can reach full maturity.
