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 Red 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: 30 to 35 days after the seed sowing, your seedlings will be ready to transplant in container pots or raised beds.
Spacing: Plant the seedlings minimum 6x6 inches from each other on raised beds or in a container.
