What Are The Main Issues With Japanese Knotweed?

A pesky plant with extensive roots, the Japanese knotweed could damage the ecosystem in your garden and even destroy valuable structures in your property. Any homeowner who has the misfortune of identifying this species in their garden won’t need an explanation about how terrible it is. But if you are lucky enough not to hear or see it in the neighbourhood, it is still necessary to get informed about this invasive and destructive species to take preventive measures. With that in mind, here are some common problems that Japanese knotweed might cause to your house. So, what are some issues with Japanese knotweed?

  1. Affect your recreation:
    In most cases, the Japanese knotweed might be a bane and a blight to allotment holders and gardeners alike, but this species might also have a negative impact on anglers. Due to its quick growth, the plant can shade lakes and rivers, obstruct access, and cause damage to the streams or banks. Other people such as canoeists, rowers, and sailors might consider its dense stand as an annoying barrier that can block their views and prevent their entry to the waterways, with the Japanese knotweed UK impacts increasingly harmful.
  1. Cause neighbour disputes:
    It seems ridiculous, but the growth of Japanese knotweed in neighbourhoods might cause a dispute between neighbours. Who will take responsibility for the invasive plants? Did it spread from your neighbour’s house to your garden? If you can’t reach an agreement and divide expenses for control, it might end up in the courts.
  1. Destroy the native ecosystem:
    Japanese knotweed has a negative impact on the ecosystem in your garden by crowding out and dominating over native vegetation, thus limiting the diversity of animal and plant species. Many studies even show the release of substances that would suppress the development of other plants.
  1. Damage buildings and structures:
    As said earlier, Japanese knotweed can proliferate at nearly a yard each week. Thus its underground stems and roots are notorious for penetrating through building foundations, asphalt, concrete walls, or even drains, thus causing severe damage. This might add considerable expense to regeneration and development schemes.
  1. Lower water quality:
    Many aquatic species can’t process the leaves of Japanese knotweed compared to other native vegetation that it replaces. As a result, it changes the whole food chain. Dense foliage in the summer leads to heavy shading of streams, thus reducing the number of aquatic plants. Also, profuse Japanese knotweed canes might lower the capacity of surrounding river channels for carrying floodwater. This will bring severe issues in rainy seasons.
  1. Cost lots of money:
    The damage caused by Japanese knotweed’s stems and roots might cost the UK’s economy millions of pounds each year in property devaluation, infrastructure damage, and weed control. Most control methods mainly rely on toxic chemicals, which can be unsustainable and have long-term effects on the environment and ecosystem.
  1. Devalue your property:
    The presence of Japanese knotweed around your garden might have a significant impact on the value of your property. In some cases, a mortgage provider can refuse your application if they notice knotweed at the house.
