Description Ammonium Sulfate 21-0-0 provides a high source of nitrogen which is what onions need to generate more foliage and therefore more rings and larger bulbs. Directions: Apply first application 3 weeks after planting, then continue every 2-3 weeks. Sprinkle 1 cup per 20 feet of row. This product readily dissolves in water and can me mixed with 1 cup in a gallon of water to treat one bunch. Apply when tops of onions are dry. Once the neck starts feeling soft do not apply any more fertilizer (approximately 4 weeks prior to harvest). Always water immediately after feeding and maintain moisture during the growing season. Onions need more water closer to harvest. 4 lb. bag will treat 150 ft. of row.
