Roundup Optima Plus Concentrate is a professional-grade systemic weedkiller designed for serious gardeners looking to clear invasive growth from driveways, flower beds, and vegetable patches. By traveling deep into the root system, it ensures long-term control of tough garden weeds, though users must be careful to avoid overspray on desirable plants as it is a non-selective formula. This 1L concentrate is highly efficient, capable of creating up to 50 litres of solution to cover large areas of up to 1500m².

To use this concentrate, you will need a clean garden pressure sprayer. Dilute the concentrate according to the instructions on the packaging to reach the desired strength for your specific weed problem. Always measure the concentrate carefully using the provided cap or a measuring tool. After application, rinse your sprayer thoroughly to prevent residue from affecting future treatments. Store the bottle in a cool, dry, and frost-free area, ensuring the cap is tightly secured and kept out of reach of children and pets. When planning to replant, ensure the weeds have fully decayed, typically allowing a few days after the final treatment before working the soil.
