Gardening and plant expert Harry Bodell at PriceYourJob.co.uk said: “Due to the ease with which Japanese Knotweed spreads and its destructive nature, tackling it yourself can be tricky.
“Complete eradication is essential to prevent regrowth, and removing the extensive root system often requires a mechanical digger.
“Also, disposing of the plant and any contaminated soil is strictly regulated. Since Japanese Knotweed is classified as controlled waste in the UK, it must be taken to a designated landfill site.
“Consulting an expert ensures proper removal, and disposal, and minimises the risk of the weed returning.”
If homeowners do decide to tackle the invasive weed at home, the expert recommended a herbicide treatment.
Before diving in, assess the surrounding area and check if there is anything nearby which could be affected by herbicide overspray.
The expert noted: “Inform your neighbours about the treatment schedule to minimise exposure risks. Choose a late spring or early autumn window when the plant is actively growing.
“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.
“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.”
The plant pro recommended using a garden sprayer for applying the herbicide as well as a roller, cloth, sponge or brush for localised application. Remember to wear gloves and shield nearby plants with protection such as a tarpaulin.
Harry added: “The herbicide should thoroughly cover the leaves and stems. For enhanced effectiveness, inject some herbicide directly into the stems near the base.
“Specialised tools are available for professionals, but a simple cut at the base followed by pouring herbicide into the opening can suffice. Once cut, place all Knotweed material in sturdy plastic rubble sacks.
“Remember, this is hazardous waste and requires disposal at a designated landfill site. Check with your local council to see if they offer any collection services for Japanese Knotweed.”
Eradicating knotweed is a long-term battle and it isn’t a quick fix, meaning it’ll need several treatments. Britons should be prepared to repeat the process two to three times a year for up to five years until it is completely eradicated.
The gardening pro continued: “Considering the difficulty of removal, disposal regulations, and the importance of complete eradication, consulting a professional for Japanese knotweed removal is the wisest course of action.
“Their expertise can save you time and money, as well as the potential headache of regrowth. If you have noticed Japanese knotweed around your property, make sure to act now to prevent any further potential damage.”
