Why is Knotweed so bad? 

A common Knotweed could grow up to 10cm per day and is an invasive species. Due to this extreme growth from the Japanese Knotweed, it has been known to cause some damage by attacking the weak points of building structures and substructures. Some weak points can be cracks within the masonry, and the Knotweed attempts to grow through these cracks and damaging the structure.

Also, the spread of Japanese Knotweed is rather difficult to control due to its growth speed, so proper maintenance must be kept in check. Among other issues, the Knotweed is often known to damage aquatic life with its roots by creating cracks in the structure of riverbanks, and the leaves are known to damage the native vegetation of other plants.

Is it illegal to have Japanese Knotweed in your garden?  

Having a Japanese Knotweed in your garden is definitely not illegal; however, having one can cause disputes with a neighbour. If you grow the Japanese Knotweed inside your garden, you must ensure that you keep it under control by performing regular maintenance on it. Knotweed does tend to go underground and past the property borders, and you can be liable to removal costs and any damages that the Knotweed has caused. Controlling Japanese Knotweed is very difficult, which is why many do not allow them in their garden.

Under the Wildlife and Countryside Act, it is illegal to allow any Japanese Knotweed to grow wild. So, if the Japanese Knotweed grows beyond your borders and control(such as into common ground owned by the government), you must alert the council or local authority about this issue. 

Steps to take to prevent Japanese Knotweed

To stop the spread of Japanese Knotweed, you can make a few preparations. These include:

Plant Looks: Understanding what the plant looks like is important. Many plants can look the same, and you should not get confused, so understanding what it looks like will help prevent its growth and spread. If the plant is caught early, this might save you some money depending on how far it has spread and what damage has been caused by it. This type of plant dies back its roots and leaves during winter and grows again or creates new shoots in Springtime. 

Treatment: Understanding that the plant is the Japanese Knotweed is important, but the treatments are also important for any affected areas. There are several ways to treat the Knotweed, such as using weed killer chemicals(like glyphosate or herbicides) to cover the plant; however, allowing a specialist to kill the Japanese Knotweed is better for ensuring it is done quickly possible reduce the amount of time wasted. Many professionals often have special chemicals that are stronger than normal weed killers; however, you cannot generally get these. Cutting the plant up or burning will not stop this easily, which is why we usually suggest having specialists help remove the infestation of this weed. The Japanese Knotweed rhizomes or roots can go around 2 metres deep in the ground. 

If you believe that the Japanese roots have grown into someone else's property, the best thing is to approach them and have it checked out. This can also reduce the damage it has done to any structures it has touched. 

What to do if you have Japanese Knotweed

Even though eliminating Japanese Knotweed is possible, it requires high levels of skills and expertise because they have extensive rhizomes that can grow up to 4 cm in a day! Meaning that the weed can become dense in a short period if it not controlled in time.

To make matters worse, Japanese Knotweed can grow in most areas and requires only a small fragment of the rhizome to propagate (the rhizome fragment can be transported via footwear or through soil transportation). Therefore, if you suspect you have a Japanese Knotweed infestation, seeking professional help as soon as possible is highly recommended.

You shouldn't try and get rid of the Japanese Knotweed by yourself, as you will end spending more money in the long run, and calling a professional will avoid the stress and hassle associated with the removal of the weed.

Applying for a Mortgage with a House that has Japanese Knotweed

If you have Japanese Knotweed, applying for a mortgage can prove very difficult, affecting the property structure and has many other disadvantages. These disadvantages may make selling your property hard and may also lower the value of your property.

Japanese Knotweed grows aggressively, and it can affect the structural integrity of a house. This is because the Japanese Knotweed exposes the weaknesses of concrete, brick walls, foundation or tarmac. Some of the problems associated with Japanese Knotweed include the following:

  • Reducing the value of the land
  • Damaging flood defence structures
  • Damaging paving, tarmac areas and retaining wall structures
  • Damaging the foundation of a building
  • Restricting access to a building
  • Aesthetic issues

Japanese Knotweed Identification

Japanese Knotweed flowers later on in the year, between August and October, so this is probably the best time to check if you have it or not. The stems of this invasive plant are bamboo-like, and they have purple spots all over them, so they are pretty easy to spot. The stems themselves can reach heights of up to 2-3 metres and not only affect your garden but also the wildlife.

The flowers on the Japanese Knotweed plant are small and are a creamy colour. They flower in groups and can be found where the leaves meet the unique and recognisable stem.
