You propagate sprouted onions by planting them in the ground, covering the white part of the onion to protect it, just as you would plant a normal onion set.
Planting Sprouted Onions:
The YouTube video excerpt provides a simple, direct method:
- Planting Depth: Cover the white part of the sprouted onion with soil. This protects it from the elements.
- Planting Method: Treat the sprouted onion like an onion set. Plant it directly in the ground.
This method effectively uses the existing sprout to continue the onion's growth cycle. Essentially, you're giving the sprouted onion a second chance to grow into a mature plant.
