KleenUp 365 Weed Control

Bonide KleenUp 365 Weed & Grass Killer kills existing weeds and grasses, roots and all, and prevents new growth for up to one year. Bonide says visible results appear within about 10 hours, and it is rainproof within hours once dry. Use it only where no plant growth is wanted, such as driveways, gravel areas, patios, sidewalks, along fences and in pavement cracks. Read and follow all label directions.
