Is that very thin onion called a thin scallion? How do you grow it?
Yes. It's called a scallion. Like onions, it can be propagated mainly by planting onion heads. Each onion head can produce 4-7 seedlings. Every summer after aging, planing out the braid hung up to dry, early fall can be planted, the use of strips can be planted, the winter can be open ground overwintering (a little bit of grass insulation can be laid). Favorable management.
