Japanese knotweed

“There are no gardening mistakes, only experiments”

 

This famous quote suggest that a plant is survived by the company it keeps. In Japan, the environment in which the Japanese knotweed grows helps to keep it under control, both with volcanic rock and insect predators. But if the plant is raised in UK, it will not face the same natural enemies. The reason behind this is that in UK there are not the same insects who attack the plant and stop the growth of the plant.

 

The native species did not exactly welcome the Japanese knotweed with open arms, but they couldn’t do much to stop it. With this in mind, to control and protect the plant would lead to an estimated £1.56 billion needing to be spent across UK. Such controls are necessary, because to retain the plant certain chemicals and cost-effective solutions are required.

 

So, is the UK’s Japanese knotweed problem getting worse?

 

The Japanese knotweed is the most impulsive and aggressive weed. If left untreated, it can spread and create problems. In UK it is a criminal offense to leave the weed growing from your land to your neighbouring property.

 

The problem with Japanese knotweed is that it grows up to 3m high, which can go through your plumbing, foundation, and even driveways. Another problem is that the plant can cause serious long-term flooding issues. The repair work that you need after the damage caused by Japanese knotweed will not be small, it can raise up to thousands of pounds.

 

In fact, the plant can even affect the price of your house and the mortgage value. If you look on the legal perspective, Japanese knotweed should be disclosed to the banks, your neighbour, and buyers of your house. When buying the house, most of the bankers will be reluctant to approve house mortgages that have Japanese knotweed in their properties. Or even if there is a slight history of the plant on the home.

 

Also, is it true that Japanese knotweed is poisonous for dogs & cats?

 

Unlike human’s dogs and cats have different digestive systems. It is reported that homes where Japanese knotweed is placed the animals face a lot of problems with their digestive systems. The plant constantly harms the health of the pets. It is also advised that not to bring any pets like cats or dogs near the plant as it may harm the pets and their health will be seriously affected.

 

The reason why Japanese knotweed survive is that the plant is made robust by harsh conditions in Japan. Where volcanos are ordinary and natural disasters are common.
