How to Sow
- Sow between 4-8 seeds per pot or cell
- For outdoor direct-to-soil sowing, create drills 1cm deep and sow the seeds thinly in 4cm rows
- Cover over with 1cm of compost, pat down and water
Plant Care
- For indoor sowing: Transplant the seedlings to soil outside approx 4inches apart whilst the plants are still small to avoid disturbing the roots
- Onion sets can also be planted for convenience in mid-Spring (plant direct to soil with just the tips poking out)
AllotMe’s Tips
- Onions are ready for harvest when the bulbs are bulging out of the soil and all of the leaves have bent down to the ground.
- Leave harvested onions to air out and dry before use
