Japanese Knotweed Removal Takes A Concerted Effort
Some plants just should have never been created as they are invasive and hard to get rid of, Japanese Knotweed removal is a job that you have to try a few methods to get rid of the plant entirely. They came over to North America from Japan as an ornamental feature in the 19th century and have been a pest ever since.
The knotweed will not grown in forested areas as they tend to be too dark. In the right conditions, however, they will take over. They are so hardy that they will grow through the cracks of a sidewalk or driveway.
One of the first things you can do is to throw a tarp over the plants to prevent sunlight from getting to them. This will smother them and they will not have the nutrients to grow. You must make sure that the tarp is large enough to cover the plants and then some area and that it is weighted down with heavy objects so that no sun can get to the plants.
You could plant on top of the tops if you are raised beds. The knotweed will not break through the tarp. You could put mulch over the top as well and put container plants on top of it. Take care not to allow the knotweed to puncture the tarp, the old cut shoots could do so. Clear them away before laying the tarp down. Another method to use is old carpet. If you see any carpet that someone is getting rid of for free you could use this instead of tarp as it will work in the same way.
Weed killer is another method that works well for killing off knotweed. The active ingredient in the following brands is glyphosate, look for Touchdown, Rodeo, Pondmaster, Landmaster, Ranger or Roundup. As Roundup is the most well know, it works systemically to kill the plant after the leaves have been sprayed. It can also be administered into the roots by injection.
Persistent cutting can be effective but you must make sure to pick up all the cuttings or they will root and cause even more of a problem. Cutting can be done before spraying and covering with a tarp. It is a lot of work to get rid of this plant and you have to be aggressive about it.
You can also dig up the plant eliminating the very invasive root system they have. They spread by sending roots out and this will eliminate much of the problem. You can then spray and cover with a tarp just to be sure you have done all you can for your Japanese Knotweed Removal project.
