Q&A Home

Thomas from Coushatta, La. writes,

Will Herbicide Granules kill weeds 1 to3 inches tall that have already started to grow,

Areas in my garden that was weed free now have weeds 1 to 3 inches tall. Will this product kill them and prevent more from growing ? Or do I have to get the area week free again prior to using this?


Since Hi-Yield Herbicide Granules does not kill weeds but prevents them, you must first remove existing weeds. If this is a vegetable garden please refer to the Hi Yield Herbicide Granules Label to make sure it it permitted to be used on your specific vegetables. For the existing weeds, it is recommended that you use a product such as Roundup Lawn and Garden Concentrate Plus. Roundup Lawn and Garden Concentrate Plus will kill only the weeds you apply it to without transfering through the soil. Please let us know if you have any further questions.
