It kills weeds and grasses down to the root while forming an invisible soil barrier that can help deter new growth for up to 4 months. Use it in spaces where you want a cleaner surface—cracks and crevices in driveways, sidewalks, and patios; along fences; in mulched beds; or around the base of established plants and trees. For best results, ensure you cover the entire area you want controlled, not just the emerged weeds.\u003c\/p\u003e\n\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eThe formula combines an effective weed killer with a long-lasting preventive barrier. You may see weeds yellowing and wilting within hours, with full elimination often occurring in 1–2 weeks. The barrier remains active after application to slow fresh arrivals, helping you maintain cleaner spaces between treatments. In addition, the product is rainproof in as fast as 30 minutes, so a light shower won’t undermine the treatment.\u003c\/p\u003e\n\n\u003ch3\u003eWhere to apply\u003c\/h3\u003e\n\u003cp\u003eThis versatile solution works on hardscapes and landscapes alike.
