Growing
Unlike traditional onions that form a single large bulb underground, walking onions produce clusters of small, marble-sized bulblets at the top of an upright stem. These bulblets are clones of the parent plant; as the stalks lean over or fall, the bulblets can take root in the soil a short distance from the original plant. This habit is how they earn their name. You can propagate them by dividing existing clumps or by using the bulblets themselves. Keep the soil slightly acidic, between pH 6.0 and 7.0, and provide consistent moisture without letting the roots sit in waterlogged earth.
As the season progresses, the bulblets begin to sprout while still attached to the main stalk. You can harvest the entire plant as a green onion, or wait until the bulblets are well-formed and use them for a more concentrated flavor. Because these do not continue to ripen once picked, harvest them when they reach your desired size. Keep the bulbs unwashed to prevent rot. For long-term use, store them in a cool, dark cellar or pickle them to preserve their pungent flavor.
