This multi-purpose product is used both as a fertilizer and as a natural pre-emergent weed seedling inhibitor for new lawns and meadow plantings. As a fertilizer it is best used on lawn grass in the fall or mid-spring. When used to control weeds in newly seeded lawns and meadows, it should be applied AFTER the grass and wildflower seedlings are up and growing. Used for weeds, corn gluten becomes more effective when used for two or more years in the same area. Use it at a rate of 20 lbs. per 1,000 square ft. or 2 lbs. per 100 sq. ft.
