The Andersons Lawnbox Grass Guard 9-0-0

The Andersons Lawnbox Grass Guard DG 9-0-0 is an all-natural solution that helps prevent weeds while feeding your lawn at the same time. Powered by corn gluten meal, this pre-emergent fertilizer works by stopping weed seeds—like crabgrass, foxtail, dandelion, barnyard grass, and goosegrass—from germinating while delivering a steady source of nitrogen for healthy turf growth. Its patented Dispersing Granule (DG) Technology breaks down into thousands of microparticles when watered in, providing more uniform coverage and better soil contact for effective results. Safe for use on all turf types and free from animal byproducts or biosolids, Grass Guard is a family-friendly option that lets you enjoy your yard immediately after application. Apply in early spring and fall before weeds germinate to help maintain a thicker, greener lawn.
