WORK WITH THE WEATHER Applying Roundup® For Lawns in calm weather, when rain is not predicted for the next 24 hours, will help ensure that it's not blown away or washed off of the treated area.

Although spraying Roundup® For Lawns on your weeds is quite satisfying, resist the urge to do it too much. It works so well; one application is usually all you need to kill a weed. And some weeds can take as long as three weeks to die. If it's still hanging in there in two weeks, give it another spray.
