1. Peel the sprouted onion slowly, leaving only the sprouted part in the middle. Remember not to damage any part of the root.

2. Prepare the pot soil and flowerpot, spread a small amount of gravel on the bottom of the pot, then pour a small amount of pot soil, then bury the roots in the flowerpot, and then slowly smooth the surrounding soil. When selecting soil, it is best to choose sandy soil or loam soil to promote root growth.

3. Move the flowerpot to a bright place, pour a little water and let it grow slowly. After a few days, the leaves can grow.
