The application of Ronstar G will completely depend on the type of weeds you are trying to prevent and the type of grass you are applying the product on and of course your location. We recommend that you contact your local cooperative extension office and speak to the master gardener on staff. He/she will be able to tell you the best time for the application as he/she will know when the weeds germinate in your region.
