Japanese knotweed is a highly invasive plant with the potential to cause a lot of property damage due to structural damage as well as affecting the value. It is why you should have the necessary buildings insurance and home insurance to help protect you financially against the devastating effects of this weed.

Here are some do’s and don’ts to always bear in mind when dealing with Japanese knotweed.

Dos

Always try to isolate any outbreak of Japanese knotweed to help avoid the risk of actually spreading it further.

Get in touch with the environment agencies and local councils for additional advice on how the weed can be effectively killed off along with how to properly dispose of the materials.

Make use of the appropriately licensed chemicals and herbicides to help you get rid of Japanese knotweed safely and efficiently. When you handle chemicals or herbicides, don’t forget to always wear protective clothing.

Get in touch with the relevant authorities to ensure that the weed is thoroughly eradicated. There are many invasive plant specialists with the relevant experience and equipment to deal with the threat that Japanese knotweed poses.

Treat knotweed outbreaks the moment you are aware of them, since the more the plant establishes itself, the greater the damage it is likely to cause to its surroundings and the harder it will be to remove.

Don’t forget to recheck any previously contaminated areas for up to 2 to 3 years after removal to ensure that no re-growth has occurred.

Make sure that any shoes and clothes that have come into contact with the weed are thoroughly checked and washed to make sure that the contamination is not spread further.

Dispose of Japanese knotweed at the right facilities and ensure that the contents are properly secured to avoid spillage of the contaminated materials.

Don’ts

Do not pull the weed out of the ground since this may expose part of the infectious crowns thus stimulating growth.

Do not integrate any part of the weed into compost since this may trigger another outbreak because of the knotweed’s resilient nature.

Do not try to dig out the weed since this may potentially stimulate rapid growth of the weed thus taking over an area faster.

Do not spread any soil contaminated with the Japanese knotweed rhizome since the root system is incredibly resilient and regenerative. Take note that anything within about 20 feet of an infected site may contain the plant’s root system.

Do not dispose of the weed in garden waste pick-ups since this may transport it to other locations. Instead, dispose of it on site by first letting it dry out then burning the remains. You can also make use of facilities that dispose of the weed professionally.

Do not use unlicensed chemicals and herbicides close to any wildlife, plants, or watercourse since you risk damaging the environment.

Do not use a hedge trimmer or lawnmower to cut down the knotweed since this may infect the surrounding areas thus making the weed harder to destroy.

Do not do anything illegal. Spreading Japanese knotweed is breaking the Wildlife and Countryside Act 1981. So, take care and deal with this invasive plant properly.
