Considering the square footage of the area needing treatment is vital when selecting a weed killer for large areas. To guarantee adequate coverage, choose a product with a coverage area that matches or exceeds the size of your space.

Check the label or product information for specifics on the effective coverage area of the weed killer. Opting for a product with a wide coverage area per container can help minimize the need for frequent refills when treating large areas.
