Like all onions, scallions are shallow-rooted, and so need the soil at and near the surface kept moist (they can't go down deep for water), but they easily "drown" if the soil gets waterlogged, which is why you don't want a heavy clay soil. Plant scallions throughout the spring and again in mid to late summer for a fall harvest. Grow in full sun.
