Coverage depends on which form of corn gluten you're using, so read the package for accurate application. In general, however, corn gluten is applied at 20 - 40 lbs per 1000sq ft. Corn gluten will not work until wetted, so wet it down using a fine soft spray after applying.One application effectively supresses weeds for 4 - 6 weeks. Heavy soils, protracted rainy weather and hot spells may require monthly application.Effects are cumulative. Results improve with repeated use over time.
