Jonathan Green Organic Corn Gluten Weed Preventer

Jonathan Green Organic Corn Gluten Weed Preventer feeds the lawn while preventing crabgrass, dandelions, and over 25 other broadleaf and grassy weeds. For optimal results, apply early in the spring—between March and early May—before weeds germinate.
