Dual Action Weed and Grass Killer Plus 4 Month Preventer with QuickHand Sprayer Refill - 50 oz

Reduce, refill, and reuse with Roundup Dual Action Weed & Grass Killer Plus 4 Month Preventer refill for QuickHand Sprayer. This formula kills existing weeds and grass down to the root, and prevents new weeds from growing for up to 4 months by creating an invisible barrier in the soil. Apply only where you want to kill existing weeds AND prevent future weed growth for up to 4 months, such as cracks and crevices in driveways, sidewalks, and patios, along fences, in mulched beds or around the base of well-established desirable plants, shrubs, or trees, and on gravel areas. With this refill bottle, you can reuse your one-hand QuickHand sprayer to target weeds in hard-to-reach places. There is no mixing and no measuring, you just connect and go. For best results, apply during warm, sunny weather above 60°F. Rain or watering 30 minutes after application will NOT wash away effectiveness. After application, weeds will begin to yellow and wilt within hours with complete kill in 1 to 2 weeks. All ornamental bedding plants (annuals and perennials), trees, shrubs, sod and seed can be planted 4 months after application.
