Japanese Knotweed is probably the most commonly well known invasive plant species in the UK. The very thought of it near a home owners property will strike fear into people due to the fact it is very hard to eradicate
Giant Knotweed is an invasive, non-native plant. Very similar in appearance Japanese Knotweed. However, as the name 'Giant' suggests, this version of knotweed grows much taller, 4-5 metres in the right growing conditions and it has much larger, elongated leaves.
Bohemian Knotweed is a close relative of the Japanese Knotweed plant, that is probably the most commonly well known invasive plant species in the UK
Himalayan Knotweed is a close relative of Japanese Knotweed that is very similar. appearance. However the leaves are much larger in appearance (very narrow and long).
Despite a display of rather pretty pink flowers, Himalayan Balsam can be extremely difficult to get rid of if it takes hold in your garden.
Although Rhododendron Ponticum produces the most gorgeous mauve flowers, it does have an extremely negative impact on both wildlife and the ecology of the site which it inhabits.

What will Jamie’s Garden Services do for you?
Once we have received contact from you the following will happen:
• Jamie will contact you to discuss the problem.
• A site visit will be arranged.
•On looking at the infestation we can talk about:
a) Identify what species of knotweed it is.
b) What the infestation is doing.
c) How it will affect your property.
d) Look at identifying where it can from.
e) What effects an infestation can physically and financially have on your property.
f) Talk about how we can move forward with dealing with the infestation.
g) Produce a Treatment Plan to deal with the Infestation.
What will a ‘Treatment Plan’ contain?
The ‘Treatment Plan’ is a document that will:
• Document the scale of the infestation.
• Contain Photographs of the current Infestation.
• Explain how the species you have spreads and what happens when it does.
• Explains how an infestation can have an effect on your property.
• Document the source of the problem (if possible).
• Outline what treatment will be best to eradicate the problem.
• Give a programme of how the problem will be treated.
• Documented a timescale of how the treatment will be implemented.
• How treatments will be followed up.
• How the infestation will be monitored during the treatment programme.
• What needs to be done once the it appears the problem has been resolved.
• What ongoing monitoring will be required.
• What future reports will be done and how they will assist you.
• An outline of what costs will be involved with treating the infestation.
• Terms and Conditions.
At this point it moves on to treating the Knotweed infestation.
Why do I need to document this treatment process?
* Should you wish to sell your property/land.
• Develop on the land.
• Comply with declarations to mortgage lenders or home insurance companies
• Comply with the LAW, (Country Side and Wild Life Act in preventing its spread).
You will need documented proof that you have undertaken all the correct actions to controls and prevent the spread of an invasive plant species.
That a Qualified and Competent person has overtaken the work.
A documented treatment plan, Treatment Process, Monitoring of the infestation will be your your proof that the problem has been dealt with, or is being dealt with.
I should point out that dealing with an invasive species infestation is not a quick fix. It does take time and you will need to be patient.
Many people have asked me if it is expensive to deal with a Japanese Knotweed infestations?
I always answer it. In the following way... I have seen some shocking figures bounded about on the internet for what people have been charged and for was was undertaken.
For conventional treatment processes and if customer has not interfered and made the task harder, then no it is not expensive. There is a cost and I would say that it is a moderate cost.
But you should be aware that it will take a few years for treatment and monitoring. I invoice for work undertaken as and when it is done on set fees that will be outlined in the treatment plan and discussed on the first site inspection.
If you want a very quick fix then yes it will be very expensive. This is because all the solid containing it will need to be excavated, Securely transported in sealed containers, and processed. (This service I don’t offer.)

• Don’t cut it down / flail down Japanese as this could cause it to spread especially when the stem is growing as it can stimulate the root system to grow instead.
• Don’t try to dig up Japanese Knotweed as this will lead to a significant increase in stem density. Even a tiny fragment of the cut rhizome is capable of regeneration and when you are digging it up you run the risk of creating multiple new plants that will reappear with vengeance.
• Any soil that is obtained from ground within 7 m horizontally and 3 m deep of a Japanese knotweed plant could contain rhizome. Don’t spread soil contaminated with Japanese knotweed rhizome in as this will create a whole new problem.
• The rhizome is highly regenerative and will readily grow into new plants.
• Don’t machine Chip/Shred Japanese Knotweed material. Mechanical chippers will not kill Japanese Knotweed. If you spread the chipped material on soil, it is highly likely that Japanese knotweed could regrow.
• It is important that you don’t dump garden waste contaminated with Japanese knotweed in the countryside – you will be breaking the law under The Wildlife and Countryside Act 1981 (as amended).
• It is important that you don’t take Japanese knotweed to recycling centres that receive garden waste as it will contaminate the compost. Don’t break the law. Remember, if you cause Japanese knotweed to spread, you are guilty of an offence under the Wildlife and Countryside Act (1981)
• Japanese knotweed, it is best to dispose of it on site by burning it. - Don’t cause the spread of Japanese knotweed stem and crowns. If you cut down Japanese knotweed, it is best to dispose of it on site.
Important Note: Don’t add Japanese Knotweed to compost. You will need to compost it separately (preferably on plastic sheeting to prevent rooting) so that you can be sure it is dead.

Under UK Law, Japanese knotweed (Plus Giant, Bohemian and Himalayan Knotweed) is legally classed as a controlled plant under the Wildlife and Countryside Act 1981 section 114 (2) (WCA 1981). It is not illegal for you to have Japanese knotweed on your property, but it is against UK law to cause or allow the plant to spread in the wild.
Under the Countryside Act 1981 it is illegal to allow to cause or allow the non-native invasive plant Species to spread in to the wild. This include neighbouring private properties where large civil claims can be made against you.
Japanese knotweed and other family members like Giant, Bohemian and Himalayan knotweed can cause a lot of damage to buildings, footings, garden landscape features (hard standings, drive ways, patios, bases, other areas of vegetation).
Its extensive and invasive root system spreads rapidly and and can break through much harder structures
It can be very hard to buy or sell a property with Japanese, Giant, Bohemian and Himalayan Knotweed.
Banks and other mortgage companies often won't lend money to your prospective buyer if there is on of these invasive plant species present on the property. Surveyors will often point this out when to any lender when you have a survey done.
I have also known Surveyors to also miss-identify other safe screening plants as an invasive plant species and refer to them as Japanese Knotweed.
This also causes great problems for the seller and it can often make a buyer pull out of a purchase.
No you should not panic at all.
You need professional advice straight away from someone who is qualified to help prevent the problem from getting worse and costing you more money to resolve.
If the invasive plant species is close to the property DON"T delay in getting advice as it could be causing damage.
DON'T CUT IT DOWN
Sadly there is no quick fix for dealing with a Japanese, Giant, Bohemian, Himalayan Knotweed or Himalayan Balsam infestations.
It will require a treatment plan that will take a number of years to ensure it is eradicated.
The secret is to get the treatment plan in place with someone who is City & Guilds NCPT Qualified straight away.
This can also be of a great help when buying and selling a property as they will be better paced to offer better advice on an infestation issue.
There are a number of plants that have similarities and in some cases subtle differences, that are most often mistaken for Japanese Knotweed:
• Woody Shrubs & Trees - Like 'Dogwood'
• Ornamental Bistorts
• Lesser Knotweed
• Himalayan Balsam
• Broadleaved Dock
• Himalayan Honeysuckle
• Russian Vine
I should mention that these plants are also very invasive.
Remember choosing to delay or doing nothing will only make the problem worse and can cost you more money in the end.
