Japanese Millet Seed is commonly used for feeding ducks as this millet will grow in flooded soils or standing water. Japanese millet duck food plots should be planted before the rainy season allowing the plant to sprout and begin growing before the standing water comes in. This millet can handle standing water if the young plant doesn't become completely submerged. Japanese millet is most successful when planted on prepared soil, although Japanese millet will germinate and grow just about anywhere. For Duck food plots, plant the Japanese millet early in the summer (June-July) depending on the start date of your duck season. Japanese millet seed heads will hold on longer than most millet varieties, even in standing water. The seed will slowly drop out of the seed head feeding the ducks over time.
