I set my mind to write and finish this article today, but now I see that I’m actually lacking words and don’t know how to start the introduction part. I guess, I’m going to become a random writer for once and just start the article with the most cliche words, such as: Hello there people, and welcome to my page!
That sounded cheesy, I have to admit! So, instead of being a random writer, I prefer to skip the introduction part and proceed straight to the topic of this article!
In this article you will read all about how to kill knotweed and what harm can knotweed cause if it’s not eliminated on time. Let’s go!
Knotweed – What Does It Represent?
Eastern Asian native Japanese knotweed was brought to England in the middle of the 1800s for decorative purposes. It was highly regarded and included in numerous renowned gardens.
It was introduced to the United States in the late 1800s and used to establish gardens, control erosion along roads, and build embankments. Early in the 20th century, Japanese knotweed was acknowledged as a hazard after escaping cultivation, replacing valuable plants.
There are known clones of a single female plant that produce Japanese knotweed in Europe and North America. The species known as bohemian knotweed is created when gigantic and Japanese knotweeds mate.
Japanese knotweed is typically found in the sun in landscapes that have been purposefully planted, along highways, and in riparian regions like stream banks. While knotweeds can flourish in a variety of soil types and lighting circumstances, they won’t be as hardy if they are growing in shade.
Both vegetatively and by seed, Japanese knotweed can propagate. New colonies can develop from extremely minute stem or rhizome fragments, and rhizomes enable knotweed to grow fast and aggressively.
Natural means, including streams, can be used to transport plant parts, but humans also frequently move soil that has been polluted with rhizome fragments or knotweed plant parts to other areas.
Only female flowers are produced by Japanese knotweed plants in North America, which prevents them from setting seed unless surrounding gigantic or bohemian knotweeds serve as a supply of pollen. After taking hold, Japanese knotweed is quite persistent.
It has been identified in 43 states and is very common in the eastern US. Infestations are common in Minnesota and can be found in both natural environments and landscaping. Many plants identified in Minnesota as Japanese knotweed turned out to be Bohemian knotweed.
How To Kill Knotweed?
Japanese knotweed is easy to control in small clusters, which can be dug up or treated with weedkiller by the home gardener. However, to handle huge clumps, we advise using a skilled, experienced service.
Using specialists has the advantage that they can create risk assessments and treatment plans with a guarantee on its complete eradication, which is typically recognized by mortgage lenders.
Due to the plant’s propensity to regenerate from small pieces of root and the complications associated with its disposal, removing it from the ground may end up causing more issues in the long term.
By eliminating all of the leaves as soon as they emerge, which prevents the plant from photosynthesising, it is possible to gradually weaken the plant. This strategy, though, can take years to work because you have to check on the plant at least once a week and cut off new leaf buds as you notice them.
The best option here is a glyphosate-based weedkiller, but keep in mind that it may require numerous applications spread out over up to four seasons to completely eliminate Japanese knotweed.
It works best when sprayed to freshly cut canes so the weedkiller can reach the plant’s roots completely. On how to control Japanese knotweed, several brands provide detailed guidelines.
To provide the best possible control while reducing dangers to you, your pets, and animals, make sure you adhere to the recommendations.
Knotweed that has been exposed to glyphosate will frequently grow again the following spring, but considerably more slowly. It’s crucial to apply a second application to this expansion.
How does Japanese knotweed cause problems?
Japanese knotweed occasionally sprouts from seeds as well. As a result, if Japanese knotweed is present in a nearby garden, it is very likely to spread to your garden through seed or its spreading roots. In order to promptly eliminate Japanese knotweed and prevent new outbreaks, keep an eye out for early symptoms of growth.
Due to its invasiveness and propensity to outcompete any vegetation around, Japanese knotweed is an issue in gardens. But it’s also an issue in the wild. It is regrettable that Japanese knotweed has escaped or been abandoned in the wild, where it quickly multiplies and poses a hazard to ecosystems.
Along railroad banks, near train stations, and on canal towpaths, it is a typical sight. It is believed that the wind created by moving traffic aids in the spread of Japanese knotweed seed.
Small root fragments of Japanese knotweed can sprout. Due to its tremendous vitality, it can grow swiftly throughout your garden and into adjacent gardens.
Its roots are known to take advantage of pipe and masonry cracks, and they have even been reported to harm highways. Japanese knotweed should be removed as soon as you notice it growing close to your home because it may weaken the home’s foundation, thus it is important to manage to kill it on time.
