Roundup Tough Weedkiller Concentrate delivers powerful systemic control for persistent weeds across your entire garden. This super-concentrated 500ml formula penetrates deep to eliminate weeds from the roots, making it ideal for tackling large infested areas, overgrown spaces, and stubborn growth on paths, drives, gravel, and borders. Simply mix and apply with a garden sprayer during the active growing season (February to November). The glyphosate-based solution degrades safely in soil through natural microbial action, allowing you to replant the following day. Perfect for preparing beds before sowing vegetables and flowers or reclaiming neglected garden areas.
