Carefully cut open onion, avoiding cutting middle section, and remove green sprout/shoots without damaging them. You may have several individual shoots to plant.
With root ends down (green shoots up), plant approximately one-inch deep, keeping bulb submerged and green shoots above soil level.
If planting more than one, space at least 2-inches apart.
Water until potting mix is moist.
Grow in sunny location never allowing soil to dry out.
Notes
You can grow sprouted onions in the ground outdoors or in containers (indoors or outdoors). If planting several, space them at least 2-inches apart. Onions are ready to harvest when the tops (greens) turn brown, floppy, and dry out.
