Bunching onions are called by different names, including green onions, scallions and spring onions.
Bunching onions can be grown outdoors from seed when the soil temperature is at least 50 degrees F. You can also start seeds indoors about 8 to 10 weeks before your planting date and transplant outdoors.
Space plants at least 1 inch apart from each other. Water enough to keep the soil evenly moist.
Keep weeds away from onion plants. Try spreading mulch, such as chopped straw or leaves, around plants to help keep out weeds and hold in moisture.
Season and Location
Plant in fertile, well-drained soil in full sun or part shade.
Bunching onions grow well in containers.
Choose a container at least 6 inches deep with holes near the bottom for water drainage.
Place container outdoors in full or part sun or indoors near a sunny window.
