How to Harvest:
Stop watering in the beginning of August to mature the bulbs in dry soil. After half the tops have fallen, push over the remainder, wait a week and lift the bulbs. Curing is essential for long storage. Spread bulbs out in the sun for about a week, covering them at night to protect from dew. When the outer layer of the onion changes from moist to dry and crisp, it is cured. If weather is poor, cure inside. Storage: Keep onions in mesh sacks or hang in braids so they get good ventilation, and hang sacks where air is dry and very cool, but not freezing. Check them regularly and remove any sprouting or rotting onions. Well-cured storage onions should keep until late spring.

Tips to Growing Organically

Companion Plants:
Beet, Carrot, Kale, Broccoli, Cauliflower, Collards, Dill, Kohlrabi, Leek, Lettuce, Strawberry
What Plants to Avoid:
Pea, Asparagus
Common Pests:
The pungent odour of onions repels many pests and also protects nearby garden vegetables.
Common Disease:
Botrytis blast and downy mildew are common leaf diseases. One starts with white spots and streaks, the other with purple-grey areas on leaves. Leaves wither from the top down and plants die prematurely. Separate the overwintered and spring crops because disease starts in older plants and moves to younger. Avoid overhead watering and plant in open sunny locations.
Bonus Grow Tips:
The soil should be fertile and well-draining. Raised beds are ideal for growing green onions.
