Can you replant store bought green onions?

It is easy to regrow store bought scallions. Once you have used up much of the green part of the onion, keep the white bulbous base with a bit of green still attached. This is the part that can be rooted and will produce new shoots.

How do you know when Green onions are ready to harvest?

There is no perfect size, just pull when they are big enough to suit you. For full-sized bulbs, let onions grow and mature. They are ready to harvest when the bulbs are big and the tops begin to turn yellow and fall over. Pull them up, shake off the soil, and lay them out to cure with the tops still attached.
