5 Things You Didn’t Know About Japanese Knotweed

Japanese Knotweed removal in New Mills is one of our key services at Bark and Branch Tree Care. However, many of our clients know very little about this invasive and much-feared plant. While we spend a lot of our time removing it during our vegetation clearance in New Mills, we also appreciate the fortitude of Japanese Knotweed. If you’re curious about some lesser-known facts about this plant, continue to read on.


Japanese Knotweed


1. It can contaminate compost piles.

Don’t assume that you can toss leftover Japanese Knotweed in a typical garden compost pile. In fact, you shouldn’t even consider taking it to recycling centres. Why? Because it can easily and quickly contaminate nearby vegetation. While it might sound like a good idea to add it to your compost pile, it can prove to be an expensive decision that you don’t live down anytime soon. You can, however, compost it separately via plastic sheeting to prevent it from taking roots in your ground.


2. Chipping it causes it to spread.

When removing Japanese Knotweed, it might be tempting to use mechanical chippers to get through it more quickly. The trouble with that is that it will cause the chipped parts of the plant to take root in your ground in other places, and doesn’t actually kill the plant at all. You’ll have to uproot it all together to completely remove it.


3. You can be fined for disposing of it improperly.

Japanese knotweed removal in New Mills is one of our more popular services because you can be fined if you do it improperly. Causing the plant to spread elsewhere makes you guilty of violating the Wildlife and Countryside Act, 1981. Don’t make any mistakes. Use our services to keep things on the up and up.


4. You need approval before using a herbicide on Japanese Knotweed.

Before you remove your Japanese Knotweed, get the approval of the Environment Agency. This is particularly true if you are using a herbicide near water. Contact the agency to get the approval required.


5. Japanese Knotweed is not invasive in its native Japan.

Japanese Knotweed is native to Japan, China, and Taiwan, and there it doesn’t cause any problems. This is primarily due to the fact that it has natural predators such as native insects, fungi, and pathogens.
