CHINESE SCALLION

Chinese Scallion (also known as Rakkyo) is a widely used spice vegetable in Vietnam, Japan, and China. It can be pickled like onions, used in salads, and is particularly delicious when served with roasted pork or duck.

Medicinal Value: Treats bloating, indigestion, joint pain, and acts as an appetite stimulant.

• Roots & Stem: Fascicled roots, long, white, penetrating deep into the soil. The true stem is degenerated into a basal plate; the false stem (bulb) is white and is the main edible part.
• Leaves: Leaves are long, linear, stiff, dark green, and glossy. Scallions prefer a mild climate and can tolerate cold.

• Soil: Grows well on light, loose soil, rich in organic matter, pH 6-6.5. Do not plant on soil where plants of the same family were grown in the previous season.
• Rotation: Crop rotation is necessary, preferably with aquatic crops (wet rice).
