Hey guys, I hope you're doing well. Hey, we are here spraying a pre emergent application on a customer's lawn here in Sandy, if you will notice we are over spraying onto the sidewalks intentionally. The reason is because this is a pre emergent application which prevents weeds. Most people, and some companies, actually don't overspray onto the concrete slightly, which means you get a lot of extra weeds right along the edge of the grass so we intentionally overspray. If you're doing this yourself, make sure you're getting your product down on all of the lawn don't skimp out make sure you go a little over and then just grab your blower and blow the stuff off of the sidewalk, but keep it right along the edges. That way you don't get weeds along the edges of your lawn this year. If you have any questions, let us know otherwise, hope you have a good day.
