Mostly use around sidewalks and driveway and wondering how long will it control the weeds?
RoundUp QuickPro can take up to 3 weeks to completely kill weeds depending on the type of weed, soil temperatures, air temperatures, rate applied, etc. This product is only going to kill actively growing weeds and does not have any pre emergent qualities. It will only remain in the soil for about 2 weeks. Please view the full product label for more information.
