FAQ

There is Japanese Knotweed growing on my property, Is it going to cause any damage?

Japanese Knotweed grows quickly but will usually take the path of least resistance – the easiest path to allow for maximum growth. Research shows that Japanese Knotweed can and will damage property, walls, fencing and drainage by exploiting any existing weakness in the structure. The plant is capable of making a small weakness far worse as it grows and expands so what was a small crack becomes larger and more problematic.

Japanese Knotweed can cause damage, but the risk is real so it is always better to act quickly and remove the risk before these problems occur.

Can I cut it back or dig it up myself?

Cutting back Japanese Knotweed will only solve your problem for a short while, it will grow back. If you are looking to remediate the problem then let your Japanese Knotweed grow so that we can offer a full range of Japanese Knotweed remediation solutions to you. There are a range of tailor made options available for the remediation; these vary from site to site, as no two sites are the same. We will help you to choose the right Management/Treatment plan for your own individual set of circumstances. Removal of Japanese Knotweed by digging it up is an option but can be very expensive as it must be taken to a specialist licenced tip by a licenced waste carrier for Japanese Knotweed, this would be impractical for most residential properties. Japanese Knotweed rhizome (foraging stem) below the ground can grow to 3m deep and 7m wide so it requires a significant dig to extract the plant in this way. In most residential cases the most appropriate method for removal of Japanese Knotweed is by using a 5-10 yr. herbicide Management/Treatment plan.

The adjacent land owner has Japanese Knotweed within 7m of my boundary, how does this affect me?

It is not an offence for a neighbour to have Japanese Knotweed on their land/garden as long as it is more than 7m away from your boundary, however Japanese knotweed spreads quickly and easily, so it is worth discussing the Japanese Knotweed potential problem with your neighbour and asking for reassurances that they are taking appropriate steps to ensure that it does not cross the boundary into your land/garden. Lenders, banks and building societies surveyors will be checking for Japanese Knotweed within 7m of your property boundary when surveying for lending purposes, (this includes re-mortgages). So, it’s also worth considering distances and once again asking your neighbour for reassurance that the plant is being treated by a suitably qualified company that is a member of the Property Care Association (PCA) nearly all lenders require this. If treatment isn’t already in place, we suggest sharing our contact details with them and we can discuss treatment options.

The sooner you discuss it with your neighbours, the sooner they can look to put a solution in place. Pass them our details today.

How long does it take to remediate Japanese Knotweed from my property?

Depending on the condition of the Japanese Knotweed when treatment starts it can take up to 3 years to remediate a Knotweed infestation. After 3 years of treatment, we look to monitor the site for at least a further 2 years to ensure that there is no regrowth. These visits take place at the end of the growing season from September onwards to ensure that the Knotweed has had every opportunity to show itself. Following 2 full years of no regrowth, a certificate of remediation is issued and our guarantee begins.

Are your treatment procedures environmentally friendly?

Whilst we use chemicals in most cases to treat and remove the Japanese Knotweed we follow strict industry guidelines set out by the HSE. Chemicals used do not persist in the soil for prolonged periods of time.

We do not spray unless the weather conditions are appropriate so chemical use is kept to a minimum and wash off into the soil and watercourses minimised wherever possible.

In most residential cases the cost of non-chemical treatment is NOT cost effective and would also lead to prolonged use of machinery and the removal of waste to landfill. We make every effort to choose the most appropriate treatment methods that would have the least impact on the environment.
