If you are planting in rows, where you will have to get in between them, leave about thirty inches between each row. If you are using a raised bed, the square foot method, in a container, or just using a corner of your garden, plant four inches apart in each direction. If you are planning to pick some for green onions or when they are small, you can squeeze the spacing down to two inches, and then pick all the ones in the center, so the big onions have four inches on each side.
