This product contains an advanced herbicide known as Dimension® that provides postemergence control, meaning it will kill existing weeds, such as crabgrass, even after they germinate. Postemergence control is limited to crabgrass and is effective for up to four weeks post-germination. It will only kill the plant up to the 3-leaf stage of growth; a fully mature crabgrass plant has 7-leaves.
