Growing Info
Harvesting: For repeated harvests of bunching onion greens, clip plants about an inch above the soil surface, and they will regrow. After cutting, apply fertilizer that is higher in nitrogen than phosphorus and potassium to encourage rapid regrowth. Bunching onions of the species Allium cepa can also form a bulb if given the time and space. To grow bulbs, harvest entire plants, leaving 3"–4" of space between the plants you want to remain and produce bulbs.
Special Care: Keep growing area weed-free. Dense weed growth will adversely affect yield.
