Find out how to get rid of Japanese Knotweed permanently.

Trust us

The only real way to get rid of Japanese knotweed permanently is to put in place an eradication management plan. UK wide coverage. Location - No extra cost.

Knotweed-free means no stress, no damages, and no repair costs.

Cutting back, and digging up the plant that you see above ground is not an effective method of dealing with it at all. A Knotweed plant can have roots that go up to four metres under ground, so just "killing" the top bit will simply provide a temporary visible belief that you have solved your knotweed problem, but the underground root system (rhizome) is still alive and kicking, and will return in a short space of time. The only way to get rid of it permanently is to attack the root system, something that we have been experts in for almost 40 years.

How Do We Remove Your Japanese Knotweed?

Timescale: 3 - 4 growing seasons

This is the most widely used solution for the eradication of Japanese Knotweed. We use a sprayer with herbicides applied to the surface of the leaf. This method is best used during the summer months when we have maximum plant growth, the more leaf growth we have the better and more effective the treatment. We visit your property and spray the knotweed twice in the first two growing seasons.

Timescale: 3 - 4 growing seasons

This method involves injecting the herbicide directly into the stem of the plant. It is primarily used outside of the main summer growing season when we have no leaf area to spray.

Stem injection is a system used when the area of knotweed growth is in smaller concentration around your property.

Timescale: On-site work, depends on the size of the infested area, normally 1-2 weeks, followed by a monitoring plan.

This method involves excavating the Knotweed soil area and either removing off-site to a dedicated landfill, or burying on site in a cell. Primarily this is a method utilized for major development and building work, but it can be used on private property, although the cost is higher than the other two methods above.

This is a quick method to remove and eradicate the infected area, and allow the use of the previously affected area without restrictions.

Once our team has moved off site, we will continue to monitor it for the full term of the 10 year insurance backed guarantee period.
