Roundup typically starts to show results within 24 to 48 hours after application, with visible wilting and yellowing of the weeds. However, complete weed death can take anywhere from 1 to 3 weeks, depending on factors such as the type of weed, weather conditions, and the concentration of the herbicide used. For optimal results, it's best to apply Roundup on a dry, calm day when weeds are actively growing.
