How to Prevent the Spread of Japanese Knotweed

Weed control is one of our top focuses on Bark and Branch. We know how difficult giant hogweed control can be, but one of the most invasive and difficult is Japanese knotweed control. Because of this difficulty, we thought we would offer a few helpful tips to help you prevent the spread of these invasive plants in your yard.

There are strict consequences for allowing the spread of Japanese knotweed in particular. You can be prosecuted or given a community protection note if it grows onto someone else’s property. Here are a few ways you can prevent that from happening.

 

How to Prevent the Spread of Japanese Knotweed

 

Use chemicals

Find and use approved pesticides on Japanese knotweed. We use a list of highly effective chemicals to prevent and kill off this invasive species, but if you go it alone you should consider this list before you start spraying.

You also want to make sure anyone who does the spraying has a certificate of competence for herbicide use or has a supervisor who does. If your plants are near water, you’ll also want to get approval from the Environment Agency.

 

Burn It

Do you own a business in need of Japanese knotweed control? If so, here’s what you need to do:

• Contact the environmental health officer on your local council
• Let the Environment Agency know one week in advance before you burn it

If you’re burning it on a private property you don’t have to do this, but you should check in with your local council to see if this is allowed. The Japanese knotweed crown and rhizome can survive burning if you dispose of it incorrectly.

 

Bury It

As always, check in with the Environment Agency to make sure burying your Japanese knotweed is allowed. Typically you cannot bury it on any property unless that property is a landfill site that has a permit. Here’s what you have to do if you want to bury it:

• Bury it at least 5 metres below the surface
• Cover it with a material that prevents it from growing through it
• Avoid burying other material with it
