Green onions

These are varieties of bulbing onion, sown in fall (they may need protection in colder areas) and harvested as scallions in spring (which is why they are sometimes known as Spring Onions). They are planted very closely together, with as many as 30 plants per square foot.

Green Onions can also be multiplanted, with up to 10 seeds in one soil block or plug tray (in this way you can grow a bunch of green Onions all at once).

There are varieties specifically bred for this purpose (White Lisbon is one), or you can just use any surplus Onion sets.

Interplanting

Onions are commonly interplanted with Carrots, but do well with many crops.
