Description for Japanese Knotweed
People who fail to control the spread of invasive non-native plants such as Japanese Knotweed could be fined or receive anti-social behaviour orders the government says.
Japanese Knotweed is a very invasive weed, originally brought in from Japan.
Introduced in the nineteenth century as an ornamental plant, it escaped into the wild and is now a costly problem, not just for gardeners. Left unchecked, it will invade large areas of land, takeout native plants, break up concrete, block paving ruin clay ponds and canals, and damage buildings.
If you have Japanese knotweed growing in your garden.
Japanese Knotweed growing in your garden, can potentially cause major problems, not only to your own garden and property, but to neighbours gardens and properties. I have listed a few tips and actions you should take to control the spread of Japanese knotweed.
The Wildlife and Countryside Act 1981 says, it is an offence to plant or grow Japanese knotweed where there is any risk of causing the plant to spread into the wild or neighbouring properties.
It also states that it is up to you the householder to control the plants from spreading. It is also illegal to dispose of Japanese Knotweed incorrectly, causing further spreading. I have included safe and legal ways of disposal on this page.
If you see Japanese knotweed growing in neighbouring gardens or on council property, try explaining to your neighbour, the potential damage to the countryside and property this will cause if left untreated. If reason fails or you spot Japanese Knotweed growing wild. The police have a wildlife liaison officer who can be contacted.
When I'm treating a large area of Japanese Knotweed, I use this concentrated 360g/l weedkiller, rather than the branded sprays, it is a lot cheaper and a lot more effective. More information on my page
First contact your local council, they may offer a collection service or have a list of sites that accept Japanese knotweed waste. If you are going to dispose of the Knotweed yourself, its irresponsible to dump it anywhere, it could regrow, its also illegal!! Any plant or soil material to be disposed of off site should be securely bagged to prevent spillage. When you leave the area of your garden contaminated with Japanese knotweed, check clothes and shoes, making sure no plant or soil material is present. It is easily spread to other parts of yours and neighbours gardens.
Finally a few precautions when dealing with an infestation of Japanese Knotweed.
People who fail to control the spread of invasive non-native plants such as Japanese Knotweed could be fined or receive anti-social behaviour orders (Asbos), the government says.
The weed is one of the most destructive plants in the UK.
The new rules mean people can now be fined up to £2,500 for failing to control it.
And companies who fall foul of the law can be fined up to £20,000.
The Home Office says these plants threaten the UK's biodiversity by crowding out native species and destabilising riverbanks. They can also do immense harm to forestry, farms, roads and buildings.
Japanese knotweed can grow through tarmac and cause structural damage to properties,
Japanese knotweed is particularly difficult to eradicate. It is very resilient and regrows vigorously after being cut down.
The most effective method of eradicating it is by using herbicides in the late summer or autumn, when it is close to its flowering sta
