It is not a secret that Japanese Knotweed can cause untold amounts of damage to your home, your garden and even your relationship with your neighbours. Although the weed itself is fairly easy to spot in terms of its appearance; at what point does it become so destructive? When should you be calling us, as Japanese Knotweed Specialists in to eradicate it, or is it something that you can keep on top of yourself as long as you catch it early?

The long and short of it is, no.
Whilst it is much better to catch this weed early, it should always be removed by professionals, as opposed to tackling it yourself. Do not underestimate this weed. It will continue to grow at an extortionate rate, even if you think you have destroyed it. The team at Japanese Knotweed Specialists have many years of experience in the industry and are experts in controlling and removing the troublesome weed.

To minimise the damage, it is important to recognise the times of the year that the plant is at its most destructive. During the summer the weed is at its most recognisable with thick bamboo like stems, with large leaves and creamy-white flowers hanging from the stems. The weed can grow up to ten centimetres a day during the summer, so it is easy to see how it becomes so destructive. The winter months are when the canes turn into woody stalks and start to decompose, however this does not mean they will not return. Come spring, you will start to notice the early signs of growth again.

So how did it become so destructive?

Believe it or not, the plant was introduced to Europe in the nineteenth century as an ornamental plant, due to its attractive appearance. However, at this time; unaware of the damage it could cause, it was dug up and replanted, allowing it to spread. When the popularity of the plant began to decrease, it was simply dug up and discarded in disused quarries and waterways – anywhere out of site. This allowed it to spread like wild fire, infecting land that would later be used to build houses on. It is only in recent decades that the true extent of this has come to light and it would appear that Japanese Knotweed just refuses to die.

It cannot be stressed enough that early eradication by professionals is essential to stop this weed causing damage. There is nowhere that this weed cannot affect, including underground damage, for example sewers and drains; hard surface damage, such as your driveway and building and cavity wall damage, which can include your home. Obviously, this is an extreme case, but Japanese Knotweed has been known to actually force walls apart.
