Thoughts and news about invasive weeds and The Knotweed Company

Japanese knotweed – do you have a problem selling your house? or getting a mortgage? Wednesday 30th August 2017

Japanese knotweed continues to spread and continues to make the news. It is in many respects a slow burning issue, typically starting as a small shoot, perhaps spread into your garden by soil disturbance. Over years it grows into a large bushy plant and then, you find out that you have a mature knotweed plant, often when you come to sell your house…

If you’re at this stage, don’t panic! We at The Knotweed Company have a team of qualified Japanese knotweed surveyors, and we are quite used to dealing with property sales and Japanese knotweed. We have a very good record of producing survey reports and solutions tailored to the property, which usually allow the sale to proceed without too much delay. Our success in this area is over 90%, although this may involve selecting a larger mortgage company, as opposed to the smaller lenders, who may have more restrictive criteria for lending on properties with a knotweed problem.

We are able to offer appropriate solutions for each property that has a problem with Japanese knotweed, and (naturally) can usually offer an insurance backed guarantee (if required).

The time to start treating your Japanese knotweed is now, so call the professionals.

We cover all of England and Wales and have surveyors & technicians in a number of locations, which include Hampshire, London, Sussex, Essex, and Northamptonshire. We also are regularly working in areas such as Yorkshire, Durham, Tyneside, Manchester and Merseyside. We have large number of contracts in Merthyr Tydfil, Newport and Cardiff and also travel into the more rural parts of Wales.

Japanese knotweed – Pay as you go. Wednesday 26th July 2017

Japanese knotweed control and eradication requires many visits over a few years before certification of eradication can be issued, needless to say all this costs money! Some of our competitors require that you pay all the costs of this programme either up front or in 2-3 payments in the first year – this can be difficult for people to fund…

We at The Knotweed Company offer a much more realistic approach to our ongoing contracts. We can (if for instance a mortgage company requires it), take the monies in one or two payments, or we can simply invoice as the works progress according to an agreed schedule. The ‘pay as you go’ approach has several advantages for our clients including budgeting of costs and keeping control of their money.

We aim to work with our clients and seek to offer a fair way of payment for services that may last a number of years. I always ask people a simple question, if you were arranging vehicle servicing for a five or six year period, would you pay the garage up front? Why should Japanese knotweed be any different?

We aim to work with our clients, we don’t have a one size fits all policy.

Giant hogweed… the killer weed Wednesday 12th July 2017

As regular readers will know, I try and avoid using scary language in these blogs. There are plenty of other websites out there that try to scare you. So why the scary heading? Well Giant hogweed is a scary weed.

Giant hogweed originates from the Western Caucasus in Southwest Russia. It is a short lived perennial typically taking 3-5 years to grow from a seed, flowering in its last year and then dying. Each plant typically produces 20,000 seeds in its final year – although it can produce much higher numbers of seeds in favourable circumstances.

Doesn’t sound scary? Well consider this: the sap from this plant is a known biohazard. If the sap (especially from a flowering plant) gets onto your skin, the sap removes your natural skin protection from normal sunlight and your skin burns and blisters when exposed to sunlight. If you get sap into your eyes you can be temporarily or permanently blinded. If you get sap around your mouth you can choke and die. Fortunately the worst cases of human health issues are rarely seen in this country, however the blistering and burning are quite common and symptoms may persist for years.

Still not scary enough? Giant hogweed sap is a known mutagen and may cause mutations in foetuses so should be of particular concern to pregnant women and other mammals.

We frequently treat Giant hogweed and use special extending lances to apply herbicide (and so avoid contact with the plant). We have been appalled by seeing some people recently who on finding out that they have Giant hogweed then decide to chop it down! This is not a good idea… even if you take a lot of precautions you are still exposing yourself to a lot of biohazardous sap and this should only be done by specialists in extreme circumstances; for instance in areas where you cannot fence the area off and/or use signage to exclude people from the area while treatment is taking place.

Japanese knotweed – It’s here, growing somewhere near you. Wednesday 31st May 2017

I like to avoid dramatic headlines, when writing this blog. However there is a time and a place, when I think you can be excused for using one. Are we winning the war against Japanese knotweed? The short answer is ‘No’. We can and do win individual battles, and nothing gives me greater satisfaction than being able to certify that a site’s knotweed has indeed been eradicated. However knotweed is still being spread faster than it is being controlled and many infestations are either not being controlled at all (let alone eradicated) or are being inappropriately treated.

Inappropriate treatment is a source of concern to me. I came across one instance the other week, where ‘Professional’ Knotweed contractors were giving some very poor advice to a client – one that could have had some serious consequences for them (heavy fines and/or prosecution) as well as environmental issues. Fortunately the client realised that this proposal was inappropriate and called us in. We rapidly devised a simple and cost effective means of enabling the client’s works to proceed and completed the works yesterday.

I started in the Japanese knotweed industry many years ago and went full time in the industry from early in 2005. Other people in the company have similar or earlier start dates, as such we can call upon a wealth of experience in finding an appropriate solution for your knotweed problem.

Japanese knotweed – Student of the Year 2017. Friday 5th May 2017

Last night, Jim Glaister and I were present at the Property Care Association’s annual Awards Dinner. I was under the impression that I was there to lead the applause for the winning candidates and to network generally.

It was a great evening, and was made all the better for me, when to my surprise, I found myself being awarded Student of the Year for the Certificated Surveyor in Japanese knotweed. I sat the exam last spring at a difficult time and had been glad to pass it, so I was truly shocked to learn that I had been awarded this prize.

Jim (who won the same award in 2015) had been in on the secret and he and Sue Uttridge had planned the surprise very well. Well done to you both!

I think this is a unique situation for any Japanese knotweed Company having two people within it, who have now received this coveted award. I feel both proud and humbled by this.
