Answer 1

Harvesting Onions

All varieties can be eaten as green onions, though some varieties are grown especially for their bulbs. Harvest leaves whenever you need. Harvest green onions when the bulb is not much larger than the leaves. Harvest dry onion bulbs after the leaves have dried. Lift the bulbs completely out of the soil. Dry the bulbs thoroughly before storing.
