How long will it keep the weeds away?
No, this is not a soil sterilizer. Roundup Pro Max is a non-selective, post-emergent herbicide that will kill anything sprayed directly. It is only a post-emergent herbicide: it will not prevent any new weeds from germinating. If you are looking for a product with both glyphosate and a soil sterilant to prevent plant growth for up to a year, then we recommend Eraser Max.
