How to get rid of Japanese Knotweed

Here is how you can get rid of Japanese knotweed, according to the experts over at

Plan Meticulously: Before diving in, assess the surrounding area. Are there nearby schools, playgrounds, or water sources that could be affected by herbicide overspray? Inform your neighbours about the treatment schedule to minimize exposure risks. Choose a late spring or early autumn window when the plant is actively growing.

Safety First: Don't underestimate the importance of proper safety gear. Wear overalls, a safety mask, gloves, and a face shield for protection. Sheets, tarpaulins, and rubble sacks will also come in handy.

Weather Matters: Choose a dry day with no rain forecast, as most herbicides can harm desired plants as well. Avoid windy conditions if using a spray application.

Targeted Application: A garden sprayer is effective for applying herbicide, but use caution near water sources or sensitive areas. Alternatively, a roller, cloth, sponge, or brush can be used for localized application.The herbicide should thoroughly cover the leaves and stems. For enhanced effectiveness, inject some herbicide directly into the stems near the base. Specialized tools are available for professionals, but a simple cut at the base followed by pouring herbicide into the opening can suffice.

Careful Disposal: Once cut, place all Knotweed material in sturdy plastic rubble sacks. Glasgow City Council states: "No living parts of a Japanese knotweed should be placed in either a domestic garden compost bin or garden waste bin (Brown Bin) that is collected by the local authority. It should also not be placed any other bins that are collected or in skips."

Persistence is Key: Eradicating Japanese Knotweed is a long-term battle, not a quick fix. A single treatment won't do the trick. Be prepared to repeat the process 2-3 times a year for several years (3-5) until the weed is completely eradicated and shows no signs of regrowth.
