Japanese knotweed, although not an altogether unpleasant plant to look at, is an invasive species of plant that is gradually choking the natural flora and fauna of the UK, including large swathes of Lincolnshire.
It is a plant that requires particular treatment as, by its very nature, some of the things we do in an attempt to be rid of it, could actually be helping it to spread.
What is Japanese Knotweed?
It is a plant introduced into the UK some years ago and it gradually invading river banks and waste land. It is a perennial plant, meaning it endures or lasts for many, many years, and is a tall plant, growing up to 3 metres in some cases.
Its stems are bamboo like, with the leaves dying away in autumn, leaving think woody stems over winter. Although it flowers, horticulturalists suggest that these flowers do not seed but rather new growth spring forth from rhizomes – a type of root system – within the soil.
Not only is it vigorous in its growing habits, it is also a plant that knows no bounds when it comes to stone and concrete; a real issue with this plant is that it can easily break through pavements and unused roads, dislodging stones and concrete.
Eradicating Japanese Knotweed in Lincolnshire
Like many other areas of the UK, Lincolnshire is affected by large amounts of this plant. As a county, there is also a plant to eradicate this plant; it takes a mixture of both chemicals and determination to be rid of this invasive and unwanted weed!
There is proving to be only two real methods of eradicating this plant…
- Chemical control – a combination of chemicals is proving effective at quickly reducing the ability of this plant to spring forth from the soil every spring. However, the correct strength and mix needs to be used and not all of these chemicals, in the desired strength are available for the public to buy. They can be used in their correct mix and strength by qualified pest controllers, which is proving to be invaluable in getting rid of this plant.
- Burning – tests have shown that even when it was thought the plant was dead, a rotting stem can cause a new stem or plant to grow in the spring; heavy ploughing and dredging has also proved to be ineffective and has, in some areas, contributed to the spread of the plant. The rhizomes have been known to also lay dormant in the soil for many years, before suddenly springing back to life. In some areas, the stems and rhizomes are collected and then burnt as an effective method of control. However, this is not recommended for customers to try; pest controllers can help in the control and eradication of Japanese Knotweed in Lincolnshire.
