Corn Gluten Herbicides

Powdered herbicides made from corn gluten keep crabgrass and other weed seeds from germinating and growing. They are typically spread on established lawns, but they also can be used in gardens where no seeds will be planted, such as in perennial beds. As the corn gluten degrades, it provides a small amount of nitrogen to the soil. Crabgrass begins to germinate at about the time that azaleas, dogwoods, and forsythias bloom, so spread corn gluten at that time for best results. Application procedures vary with the particular product; be sure to read and follow the directions on the label. Do not use corn gluten in newly seeded lawns, or in garden beds where you plan to sow seeds.
