Control Methods

Can’t I just zap it with a bit of weed killer?

Japanese Knotweed in Northern Ireland doesn’t react like normal weeds to herbicide treatment. It needs to be hit with specific herbicides, using particular application techniques and adhering to the correct season for the most effective results.

The techniques we most commonly use to include

  • Foliar herbicide application using a range of approved chemicals
  • Stem injection
  • Root Barrier installation. Especially useful along boundaries, using patented Japanese Knotweed Root * Barrier.
  • Deep cell burial and bund formation.
  • Incineration

Control in sensitive areas

Japanese Knotweed grows very well in river and shore side locations.

Legislation controlling the use of herbicides states that application of herbicide commercially requires operator training and independent certification through the NPTC system (National Proficiency Test Council) to attain your PA1 foundation module and PA6A your application module.

The application of herbicide in areas adjacent to water requires a specialist certification “bolted on” to your standard NPTC certificate, which is the PA6AW.

Types of location

Hill sides, river embankments, waste ground, landfill sites, areas of special scientific interest(SSI), RSBP bird sanctuary and protected areas, development ground, private gardens, hospitals, universities, housing folds, schools, port side docks, lough shore estuary, cemetery’s, nature areas, council housing sites, and so on…………

Japanese Knotweed isn’t fussy where it grows and we’re not fussy where we treat it. Our task is to track and treat it wherever it is!

Continual development

One of our aims is to ensure we use and promote the most effective systems for the treatment of Japanese Knotweed in Northern Ireland. For the past 3 years we have been monitoring our chemical formulations and concentrations of chemicals. This year we have been trialing different types of Stem Injection equipment as it hits the UK market.

Our business is the control of Japanese Knotweed, an integral part of our business is to monitor, explore and develop our control techniques. It is not simply enough to follow; we have spent years working with herbicides, equipment and sites and watched how different treatment systems work. It is a continual and ongoing part of our business. We are always adding to our collection of publications, books and research papers on JK treatment. We attend conferences, seminars and talks and meet with others who are happy to share their knowledge as we are with them.

Isn’t it better to know you’ve got the most effective and efficient treatment technique – we think so!

Training and Awareness

Landscaper Holywood

We also deliver training and awareness courses on Japanese Knotweed. They run on demand and are popular with project managers, surveyors, estate managers, architects, specifiers and anyone in general who may come into contact with Japanese Knotweed and needs to be aware of the problems it may bring to a project or site. They run in small groups and are what we would term “hands on”. - Part classroom based; part site based.

We expect candidates to leave the course knowing what the offending plants looks like it all its guises and at different times of the year. Control methods, treatment equipment and management planning can all be covered. We hold demo models of all the various stem injection equipment currently available in the UK. Candidates can familiarise themselves with it during the practical session.

General Advice

This is often the first stage that many of our clients engage with us on.

They've come across a plant that looks suspiciously like knotweed but they're not sure. Or someone has mentioned there is advancing weed in a neighbouring plot and they're not sure what it is but someone has mentioned knotweed to them.

We get calls like this all the time. We can have a preliminary chat on the phone, sometimes backed up by a photo sent to us to get an idea what they are talking about. These types of calls commonly progress to the next stage.

Management Plan

This is the document most often sought by lenders, solicitors and the Environment Agency. Also when a site is part of a planning application various stakeholders normally want to see a Management Plan in place.

This document includes a full survey of the site, quantifies the areas where knotweed has been sighted, details locations, growth stages and maturity of the infestation, details control and eradication strategies along with costings for those options. This is a comprehension document, specific to the site and forms the basis for dealing with the knotweed on that location. It should be updated on a yearly basis and should be made available prior to anyone carrying out groundwork on the site.

Our main surveyor as well as being a graduate Horticulturist of 30 years is also a qualified Property Care Association (PCA), Certificated.

Mortgage Reports

When a client is purchasing a piece of ground with knotweed present or on an adjacent site that may impact on the primary site, lenders often require a mortgage report to assess the severity of the infestation.

They want to know what the cost of control or potential treatment costs are going to be over a period of time.

A lender wants to know the cost implications if they have to take control of a property again and that it is not significantly compromised by knotweed.

Surveys

This involves a site visit by a surveyor.

They have a chat with the client, gauge the extent of the site and then get to mapping and surveying the site for knotweed, plotting locations and quantities as they cover the ground.

These surveys can also be to confirm whether or not there is knotweed visible on a particular piece of ground.

Privacy Policy

About

Unlike the privacy policy on most websites, this one isn't copied from a generic template; it's been written from scratch by humans who have considered what modern websites do, how most people interact with them and what most people are bothered about when it comes to online personal data.

We've avoided legal jargon and covering every minute detail down to the nth degree. Instead, we've focused on what we consider to be the essential stuff and answering some of the real world questions you might have.

Overview

We respect your right to privacy and will always do our absolute best to ensure we conform to not just the laws at the time, but also our moral obligation to you. That's why we will never knowingly allow anyone to use any data about you that we hold unless legally required to do so, and we will always keep it secure and (where possible) will remove all trace of it at your request.

We usually only hold names and email addresses you provide us, but at times we may hold other identifiable data about you, gathered with your consent, to carry out our day to day business with you. For instance, you might supply us with data as part of an enquiry, or as part of a purchase, or a booking process for a service, etc. In all instances, this data is destroyed once it is no longer relevant or required or held securely if it forms part of a service agreement with you or there is a legal requirement for us to retain. In which case we can hold data for up to seven years. Like most websites, this site uses cookies (read more about them below) and also like most websites this site may share your IP address (read more about them below) with some online services. By continuing to use the site, you agree to this. We don't do either of these things because we're evil, it's just for a modern website to work the way most people want them to work, you have to! DON'T PANIC though, for the majority of users you're not directly identifiable by these actions. Big Brother isn't watching!

Cookies

They are used mostly for good: To improve your experience, sometimes for bad: Search engines, Social sites etc. may use them to track what a computer (the computer, not the person) is looking at. Many like Google will use them to target you with adverts and for analytics, which results in them being able to build a profile of what you do online. You will get these cookies added to your computer when you land on certain websites, like Google, Youtube, Facebook etc. This site makes use of Cookies, mainly so we can be sure to only show you certain content once, for example, popups or reminders.

Cookies can sound a bit Orwellian and "Big Brother", but mostly they're pretty harmless and unless you land on a website that requests your data and you offer it, the data they hold is mostly anonymous, they don't have your name and email address etc. You can clear out your cookies by clearing your browser history. However, as we said this site from time to time will use cookies (never for data gathering or advertising). It is generally good practice to install a cookie manager so that you can see what websites install what cookies, as most have them but few admit to it.

Cookies generally fall into three categories: Session, 1st Party Persistent & 3rd Party. A fuller explanation of these is at the bottom of this privacy policy.

IP Address

An IP address is a unique number that identifies your computer on the internet; it is in the form of 111.222.333.444. Lots of services, like YouTube, Facebook etc., requires that websites send them your IP address before they allow sites to display things like embedded video, or Facebook elements, and so on. In reality, your IP address isn't personal data, as 99% of the time, you can't be identified by it. Regardless, some consider do consider it as such, so to keep ourselves in the clear we've added this bit to our privacy policy: On occasion, your IP address may be shared with some service providers. Emails Emails are typically kept until our inbox is full and we have a clear out and delete or archive all the old ones. We never use addresses obtained from emails for anything other than responding to the emails you send us. We don't harvest these emails for other purposes. Once we clear out our inbox and delete old emails from you, your details are gone.

It includes a clear indication from you that you wish to be added to our newsletter list. There is no ambiguity in our signup process; you can’t sign up by mistake nor can anyone signup with your email address due to the double opt-in/2 step verification. We record the location, time and place that you signed up.

We don't share our newsletter lists with anyone else, other than the service we employ to send out our newsletters.
