Raised beds or raised rows called furrows made by mounding up soil are ideal, especially if your soil is heavy clay.

Although they actually recover well from drought and start growing again when watered, it is best to keep the soil consistently moist until the bulbs enlarge.

- Growing tips: Easy to grow. Plants will appreciate a starter solution of liquid fertilizer after planting. Watch for tiny black onion thrips and aphids, which suck sap from onion leaves. These are hard to see because they hide down in the folds and neck of the leaves. Also weak plants that slowly wilt may be infested with onion root maggots, the larvae of a common fly.
