Japanese knotweed can grow up to three meters tall, and its roots can extend up to seven meters underground. The plant is most commonly found near watercourses, in roadside verges, and in waste ground.
If you think you may have found Japanese knotweed on your property, it’s important to get a professional opinion before taking any action. An experienced ecologist or surveyor will be able to confirm whether you have Japanese knotweed or not.
Japanese knotweed can be difficult to get rid of because of its deep roots. The plant can regrow from small fragments of stem or root, so it’s important to make sure you remove all of the plant material.

Japanese knotweed is an invasive species in North America. It was first introduced to the United States as an ornamental plant in the late 1800s and has since spread to every state except Alaska. In Canada, it is found in all provinces except Nunavut and Prince Edward Island.
Knotweed can grow in a variety of habitats, including forests, fields, roadsides, and even cracks in concrete. It is most commonly found along rivers and streams, where it can form dense mats that crowd out native plants and alter the ecosystem.
Japanese knotweed is particularly difficult to control because it can reproduce vegetatively from just a small piece of stem or root. This means that even if you get rid of all the visible plants, the roots can still regrow and the infestation will continue.
Knotweed Dormancy – there’s More to it than Meets the Eye
Early autumn is the time of year when most plants start to die back, preparing for winter dormancy. But knotweed doesn’t play by the same rules. This tough plant can carry on growing right up until the first frosts, meaning that it can be a real problem for gardeners trying to get rid of it.
But there is a silver lining to this dark cloud – once the plant has gone into dormancy, it becomes much easier to kill.

How to remove Japanese knotweed
Organic methods of removing Japanese knotweed
Organic methods include solarization, smothering, and using herbicides. Solarization is a process of using the sun’s heat to kill the plant. Smothering is a process of covering the plant with an impermeable material, such as black plastic, to prevent it from getting sunlight. Using herbicides is a method of killing the plant with chemicals.
The best time to remove Japanese knotweed is in the fall or spring. This is because the plant is less active and has fewer leaves during these times of year.
To remove Japanese knotweed, you will need:
- a shovel
- a spade
- a hoe
- black plastic sheeting (optional)
Step One: Dig up the plant.
Start by digging around the plant with a shovel to loosen the soil. Then, use a spade to dig up the roots of the plant. Be sure to get as much of the root system as possible. If you can’t remove all of the roots, don’t worry – Japanese knotweed is very resilient and will likely regrow from even a small piece of root left in the ground.
Step Two: Remove any remaining roots.
Use a hoe to dig around in the soil and remove any remaining pieces of Japanese knotweed root. Again, be sure to get as much of the root system as possible to prevent regrowth.
Step Three: Cover the area with black plastic (optional).
If you want to make sure that Japanese knotweed does not regrow in the future, you can cover the area with black plastic sheeting. This will prevent sunlight from reaching any remaining roots and will eventually kill them.
Chemical controls of removing Japanese knotweed
You can use herbicides to control and remove Japanese knotweed. Glyphosate is the most effective chemical for this purpose. You can either purchase it from your local gardening store or online.Another option is to hire a professional company that specializes in Japanese knotweed removal. This may be the best option if you have a large infestation of Japanese knotweed.
If you’re looking for a more natural way to remove Japanese knotweed, then consider using boiling water. Boiling water will kill the plant’s roots, so it’s an effective method for removing small patches of Japanese knotweed. However, this method is not recommended for large infestations, as it can be time-consuming.
Whatever method you choose, make sure to dispose of the Japanese knotweed properly. You don’t want to spread the plant to other areas of your garden or yard. The best way to dispose of Japanese knotweed is to dig it up and put it in a bag. Then, take it to your local landfill or incinerator.
Disposing of Japanese Knotweed
The best way to dispose of Japanese knotweed is to dig it up and send it to a landfill. You can also burn it, but make sure you do so in a controlled environment. Do not compost Japanese knotweed, as this will only spread the plant further. If you have Japanese knotweed on your property, it’s important to take action and get rid of it as soon as possible. Taking care of the problem early will make it easier to control and prevent the plant from spreading.
As with any plant removal project, there are some safety concerns to keep in mind when getting rid of Japanese knotweed. First and foremost, always wear gloves when handling the plant, as its sap can cause skin irritation. Secondly, avoid letting the plant come into contact with your eyes or mouth, as it can also cause irritation if it comes into contact with mucous membranes. Finally, be sure to dispose of any removed plants properly so that they don’t spread to other areas.
With those safety considerations in mind, let’s take a look at some of the most effective methods for getting rid of Japanese knotweed.
