Both products are great for use in cracks and crevices in your patio, driveway, walks and gravel areas. Just select the weed-prone area you want to treat and spray the entire area, not just the emerged weeds.
With just one simple application, you can spend less time worrying about weeds and more time enjoying yourself. Do not use in areas that will be planted or seeded within four months or around unestablished plants, shrubs or trees (see label instructions). See Roundup® Family of Products Usage Chart for more information.
