You need an area for your green onion bed that is at least 12 inches by 18 inches. Spread four inches of compost on the soil surface along with a sprinkling of blood meal. Using a trowel, work the compost, blood meal and top six inches of soil together.
Dig a one-inch hole, and place one onion set inside it. Space the onion sets at least one inch apart. Cover the sets with soil.
Water the onions well after first planting them, and continue on a regular basis as they grow. The soil needs to remain moist at all times.
Once the onions emerge and reach a height of three inches, thin them so that they are spaced every two inches.
After thinning the plants, spread a layer of finely ground mulch on the ground around them. Bark or sawdust work well for this purpose.
