    Issues Relating to Japanese Knotweed

    Japanese Knotweed was first imported to Great Britain from Asia in the mid 1800’s as a sturdy and good looking ornamental plant.

    Incredibly quick growing and spreading it became popular quickly throughout the UK with gardeners and landscapers alike.

    However, gradually it’s quick and aggressive spread started to find it’s way outside of it’s intended boundaries and became popular alongside wastelands, railways and waterways as the disturbed soil in these areas provides the ideal conditions for it to take root and begin further spread.

    The spread of knotweed has become such an issue that it is now considered an invasive, non native species and although it is legal to have it on your land it is illegal to plant it or cause it to grow in the wild.

    With it’s incredibly robust and fast spreading rhizome / root network, Japanese Knotweed spreads aggressively away from the host plant and if left unchecked can penetrate surrounding properties and areas by exploiting any weaknesses in it’s path, whether they be in walls, foundations, drives or outhouses.

    It can cause extensive damage to neighbouring properties and create numerous legal issues if ignored and left to spread which is why getting professional advice is imperative before beginning any treatment and management plan to make sure that your knotweed problem is tackled safely and effectively to keep costs to a minimum.

They have executed the management plan to the letter and there’s been no disruption to our lives or our DIY renovation.”

    James from Clearsafe surveyed our clump forming Black Bamboo and recommended how to remove it effectively from our border. James then attended on an agreed date and removed the Bamboo. The only way you would know any work was completed in the garden is the Bamboo is not there. James is very professional and we would highly recommend him. Thank you James for your help, it is very much appreciated.

    Responded to my email query within 24 hours. James called to my property and explained clearly what needed to be done. Totally professional and helpful without wanting to charge me for work that didn't need doing. Excellent.

    Excellent service, highly recommend. I had a letter from a neighbour concerned there was a canopy of knotweed on our border coming from my side. I contacted Clearsafe after work looking to book an assessment and James kindly said he’d pop over that evening! James quickly confirmed it was not knotweed, was likely a fruiting vine and sure enough found some small fruits. He kindly went with my neighbour to assess the border from their side also and confirmed there was no knotweed. He explained the differences in the stem and leaves and what to look for. Incredible service, professional and friendly. It was incredibly stressful thinking there was knotweed but James was very kind, knowledgeable and reassuring. Highly recommend.

    We are in the middle of purchasing a property and it was brought up in the survey that JKW was likely to be present. We contacted several JKW specialists in the area. Clearsafe went above and beyond. In a matter of hours they had identified the plant and offered invaluable information, advice and support to help us progress with our sale as well as providing us with excellent quotations. I will not be hesitating to use or recommend this company in the future.

    We’re in the process of putting our house on the market and concerns were raised as to whether some weeds in the garden were knotweed. Contacted James who requested photos. He came back to me within an hour in between other jobs and was able to not only confirm it wasn’t knotweed but tell me exactly what the weeds were. Really appreciated his friendly but professional approach and quick responses. Would highly recommend.

    Had a bamboo patch in the garden out of control. Phoned up, sent a video of the area and within weeks it’s all been sorted. Credit to the lads, they were on time and put a shift in even when the sun was on full beam. Will definitely be recommending you to friends and family. Thanks again
