Just what is Knotweed?

Knotweed is called Fallopia Japonica, it is an invasive weed which is a plant from the dock family and it ordinarily has sheaths where the leaves join the stems.

Japanese Knotweed is known as a highly intrusive plant that can mature rapidly, overtaking other plants and flowers close to if it is left to its own devices. Knotweed is challenging to remove and its existence on or near to a property could have an effect on home sales, purchases and bring about unanticipated expenses.

Knotweed features a really wide and incredibly strong root system. The roots can develop 3 metres down in the earth and 7 metres wide and upwards. It grows quickly, at a rate of greater than a metre a week. The roots can impact existing structures and make it difficult to build foundations and incorporate drain systems into the ground however it doesn’t grow through solid concrete.

It is very difficult to remove 100 % of the roots effectively and in case a tiny piece of its grass root is not entirely eradicated, it’s going to rapidly recover and spread.

Knotweed is known to target weak points, such as cracks in masonry, and can be persistent in growing through them if not extracted.

Exactly Where did Japanese Knotweed originate?

A Dutch doctor called Phillipe von Siebold came to the British Isles in the late 1840’s and began to market Japanese Knotweed to botanical gardens as well as society people.

The Brief History of Knotweed

By 1869 it became readily available for general sale in the united kingdom and farmers began to use it as feed for their animals. By the late 19th century home gardeners urged people to buy and plant knotweed in their home gardens to create a little greenery. Little did they know the disastrous effects knotweed may have from their rapid growth and plant’s roots.

The consequence of it being widely brought to a home or open public gardens resulted in it spreading quickly and growing in the wild. By the 1930’s the consequences and impact of knotweed began to be realised and its reputation for being a wonderful evergreen plant swiftly waned. Its invasive nature, roots and ability to propagate and establish easily were starting to show.

During Winter knotweed dies back to ground level but in early summertime, the bamboo-like stems emerge from rhizomes deep underground to shoot to more than 7ft high, whilst suppressing all the other plant development under and also over the ground.

The Wildlife and Country Act made it an offence to introduce Japanese Knotweed into wild areas three decades ago and by 1998 a survey revealed that the weed-covered an enormous area of 99 hectares within the Swansea region alone.

In 2011 aphids were introduced in Swansea to try and eliminate the widespread knotweed however it was without the result that was needed. An aphid is a small insect which feeds by sucking sap from vegetation; a blackfly or greenfly. Aphids multiply speedily, at times producing live young without mating, and large numbers can cause extensive problems for everyday homegrown and wild plant life.

Since this time, the government continues to be at a loss for a way to correctly control knotweed in the UK, so there are now companies which specialise in removing knotweed.

Are there any benefits of Knotweed?

Some people believe there are a few health benefits from Japanese knotweed, which includes; its capacity to prevent and treat cognitive disorders, increase heart overall health, lessen your probability of many forms of cancer, reduce digestive problems, lower blood pressure levels, sustain proper insulin levels, and more.

Can you get a mortgage on a property or home with Knotweed?

It’s not necessarily impossible to get a mortgage for a house with knotweed, having said that, banks are invariably very cautious because of its capacity to disperse rapidly. Additionally, buyers and banks are clearly careful when considering purchasing a home or land in which knotweed is found.

Home Owners Insurance and Cross-Boundary Complications

Insurance for a home with knotweed can be extremely difficult.

Most buildings insurance policies do not cover you for problems attributable to knotweed. If your neighbour has knotweed and your home is impacted by it, most insurance firms may very well go after others for the cost of damages caused to your house.

The hapless circumstances of homeowners suffering from problems in advertising their house, as a result of knotweed infestation on nearby territory have become progressively frequent in recent times and it normally comes within the realms of risk category 3 to 4. It can turn into an uncomfortable situation and it has been the fundamental cause of acrimonious and extended neighbourhood quarrels.

Whilst there’s legislation which may be pursued to encourage the landowner where the contamination lies, into arranging remedial work, in truth the regulations is quite weak and certainly wasn’t introduced by the United Kingdom government with the matter of Japanese Knotweed at the forefront.

To sum it up, we advise you to be very cautious if you’re planning on buying property or land where knotweed is discovered. Costs to eliminate knotweed can escalate and the whole removal is not always guaranteed due to its ability to propagate from one very small root and its fast growth.

Knotweed Myths, Misconceptions and Facts

There are numerous common myths about tips on how to eliminate Japanese Knotweed along with what the best course of action to take is. Putting sea salt, diesel, caustic soda, turpentine, fairy liquid on the plant or into the soil are just some of the most popular myths which seem to have gathered momentum in recent times.

  • The subsequent statements are NOT legitimate:
  • It’ll grow through solid cement
  • It can destabilise foundations
  • It has the potential to result in structural damage
  • Knotweed may damage structures particularly if left to cultivate unhindered for many years
  • This invasive plant can have such a remarkable effect on buildings, foundations & cement

Basically, if groundwork and building work has been performed to a good standard in the past, then knotweed won’t grow ‘through solid concrete’, it does not destabilise sound foundations, it doesn’t lead to architectural damage, it will not ‘damage buildings’ and it won’t have a dramatic impact on any ‘solid structure’. These claims are mistaken and in many cases, bogus.

The real truth about knotweed is that is a wild plant and it will grow and spreads quickly overtaking other plant life close to it.
