Factors That Make Japanese Knotweed Removal So Difficult

While there are always different industries where people are quick to say that you need to call a professional, it seems like Japanese Knotweed removal is somewhat over hyped. It can’t be that hard to remove a plant and ensure that it doesn’t come back, can it? Actually it can, and most people who try to remove the plant themselves find that they have actually caused a bigger problem than they initially had. There are a number of factors that play into this issue, but most of them have to do with the nature of the plant itself.

The Japanese Knotweed is an extremely aggressive plant, known for taking over large ares of land at a speed of 4cm a day or more. This means that in just a few weeks it can cover several feet of land per plant and the plants tend to create a number of seedlings each time that they expand as well. These plants are able to grow alongside each other, choking out all other plants in the area and ensuring that they completely cover everything that they come into contact with. This often becomes a problem when the knotweed is found in private gardens and places like public parks.

This plant also becomes more hearty as it grows, creating extensive root systems but also becoming more resistant to poisons and anything else that might affect the lifespan of the plant. This means that it is extremely important to tackle it early on. However, most people aren’t going to see the plant before it becomes a problem, instead thinking that they are dealing with a smaller type of plant, ignoring the very real problem that they are facing. People who are able to identify it early on and who work towards removal in a timely fashion will find that they have much better results.

The plant is also able to grow from the smallest bits of itself, even after it appears that it has all been cleared away. This problem can be seen in gardens where care was taken to pull out all of the roots, the plant was taken and burned, and the ground was even raked to remove bits. However, unless all of the land was fully treated, it is likely that a stray piece of a root or something similar will still be in the soil, allowing the plant to grow back.

Finally, the plant is able to lay dormant for a long period of time, making it even harder to kill than most people would think. If it is killed off near the top, it will grow deeper roots before it reaches the surface again, making it nearly impossible to remove.

Understanding the different factors that make Japanese Knotweed removal so difficult is one of the first steps towards making a decision about the removal process. Understanding that you need to take a large amount of care with this particular plant will help ensure that your garden is free from this invader in a reasonable amount of time.
