Damage & Protection
The damage that Knotweed can do belies the fact that it was originally introduced to the UK as an ornamental plant, but it soon became a menace with a reputation for damage and destruction including:
- Weakening of house and building foundations
- Integral damage of roads, pathways, and paved areas
- Damage to free stanading structures such as walls & pillars
- Destruction of native wild-life habitats
- Unseen damage to underground pipes, drains, and ducting
Japanese Knotweed Control
One of the main reasons for failure in controlling Japanese Knotweed lies in it’s root systems (rhizomes). These systems are incredibly extensive and deep rooted often extending some 3 metres into the ground and 6 metres outwards. If you kill just the visible part of the plant you can guarantee it won’t be the last you see of your Knotweed problem

Our professionally administered treatments ensure that the right combination of herbicides is applied in the right place, at the right time, and such is our success at removing Knotweed that we guarantee you won’t see it again.

Japanese Knotweed Identification
Knotweed has a hollow stem with a bamboo like appearance. The plant can grow to heights of 5-6 metres. The leaves are spade shaped and produces chains of white flowers/seeds.
Originally native to Korea, China and Japan once introduced into Europe Japanese Knotweed has been very “successful” and spread quickly to cover large areas particularly canal, railway sidings and levees. Stems emerge through concrete and tarmac with apparent ease. The plant is adaptable, tolerating various types of soils and appears to have a high tolerance for acidity alkalinity and salinity. In short it grows just about anywhere. Frost appears to damage the above surface stem and leaves but the rhizome or root system survives.
The plant has thick cuticle like skin on the leaf. The seeds are sterile The plant spreads by developing a large network of rhizome which root as far as 3 metres and can travel underground and spring up distances of up to 6-7 metres away from the parent plant. The plant is classified as invasive in the UK and can cause serious damage to brickwork and concrete of drains and buildings. Land owners have a legal obligation to control Knotweed on their land.
Rhizome Root System
Control has to be focused on the rhizome in order to defeat this plant as it appears resistant to cutting coming back even stronger in some cases. Lawn and Weed Expert and its sister company Taylor Total Weed Control Ltd have a great track record controlling Japanese knotweed. We have killed Japanese knotweed for years and will continue to eradicate it for years to come. It is unnecessary to spend significant amounts of money. Digging out the plant (digging down 3 mtrs) is expensive as is transporting the soil and waste to a licensed site. All of this expensive work can be avoided if a sensible herbicide program is used.
