Answer: If scallions are getting what they need, then they should not fall over. They grow best in a rich, humusy soil that is well drained but retains adequate moisture. Once they reach a certain stage in maturity, it's natural for onions to lean over andlose their green color as the bulb gets set for its long winter nap. If you live in a windy location and want to stake them, place stakes at each end and within the row as needed, and run a piece of twine on either side of the row to support the tops.
