Over the past few years, Japanese knotweed has been getting a lot of negative media coverage. This is because many consider it to be the most destructive, invasive and aggressive plant they have ever come across. The plant has such a negative environmental and economic impact that it has affected the sales of residential properties.
Potential buyers of property have even in some cases been denied a mortgage on properties affected by knotweed. Complete eradication of this noxious weed requires determination since it is very hard to remove by hand or eliminate using chemicals. Here are some methods on how to get rid of japanese knotweed.
Use of chemicals
It is important to eradicate the spread of Japanese knotweed immediately it has been identified. This is to ensure that its roots do not move any further on your land. A number of glyphosate-based herbicides can be used to eliminate the weed. When making your solution, ensure that you follow the manufactures guidelines to the letter. Since this plant is very resilient, one application may not kill it, it may only weaken it. You will need to apply the herbicide repeatedly until it can no longer regrow.
Removal by excavation
This is definitely one of the most effective ways of getting rid of the weed if time is your priority. The excavation process involves removal of the weed including the rhizome-network it has formed around the marked area of infestation. Any rhizomes left in the ground after excavation could lead to the regrowth of the plant.
The material that has been excavated can either be taken to a licensed facility, be placed in a waste-management area or placed in a burial pit. To avoid cross-contamination it is advisable to seek the help of an expert when using this method to eliminate the weed. Only an expert will be able to determine how to get rid of Japanese knotweed in your own case.
This is an environmental-friendly and innovative method of getting rid of the Japanese knotweed. Using this method, a mesh layer is employed to turn the growth of the weed against itself. The method forces the weed to detach its stem, exposing it to rot and frost. The plant eventually dies off once it has weakened. One of the major advantages of this method is that there is very little disturbance to the surrounding environment.
To ensure that the plant never regrows, you can combine a couple of methods. If you have decided to use the herbicide, you can mow the weeds before the application of your solution. You can then burn the waste once it is completely dry.
