How to grow onions

1. Planting

Prepare a flowerpot, add suitable soil into it, then use your fingers or other tools to dig a small hole, about 2 to 3 cm deep, plant 4 to 5 onion seeds, and then cover them with soil. Plant them at a certain distance. After sowing, pour appropriate amount of water and keep them in a warm place. After about 3 to 4 weeks, the onions will grow to 15 to 20 cm and can be harvested.

2. Planting onion roots

When buying onions for consumption, buy fresh ones with plump roots and root hairs, preferably with a small amount of soil on the roots. Cut off the scallion roots together with a small piece of scallion white, leaving about 7 cm of the scallion white part. Then plant the scallion roots in the soil and water them with appropriate amount. They can be harvested after about a few weeks.
