*The Environmental Protection Act 1990 states that Japanese knotweed is classed as “controlled waste” and as such, must be removed by licenced organisations and disposed of safely at a licensed landfill site that can accept knotweed according to the Environmental Protection Act (Duty of Care) Regulations 1991.

Dispose knotweed waste in accordance to the law

As Japanese knotweed is an aggressive and invasive species of plant, it is important to dispose of the knotweed waste correctly and in accordance to the law. If you fail to do so, you can be fined or imprisoned for up to 2 years.

All knotweed waste is classified as “controlled waste”

Treating Japanese knotweed with chemicals is unlikely to eradicate it as it has deep roots and rhizomes which can remain viable in the soil for a long time. It can remain dormant, but will eventually re-grow and for this reason, the Environmental Agency (EA) state that any ground or soil containing knotweed stems, roots and rhizomes (dead or alive) should be classified as controlled waste if removed from the site.

Transfer knotweed waste to a licenced facility for disposal

Knotweed waste must be handled in accordance to the code of practice for the management of Japanese knotweed published by the EA. This means removal of knotweed stems and knotweed contaminated soil from your residential or commercial property is difficult, due to legal restrictions.  You must dispose of Japanese knotweed waste off-site by transferring it to a facility that is licenced for the disposal of invasive weeds.

Japanese knotweed advice

  • Do not build on knotweed. If you are adding an extension to your main building, excavate the area and remove the waste correctly.
  • Knotweed roots can exploit existing cracks and gaps in drains and other buried services in their search for water. In some cases, drains become blocked and in worst cases, the drains need to be renewed.  Again, remove the contaminated soil and dispose of correctly.
  • Japanese knotweed can grow between patio paving slabs, expansion joints of concrete drives and disrupt brick paving. Do not undertake hard landscaping without removing the contaminated soil.
  • Closely packed Japanese knotweed stems can undermine garden walls with shallow foundations to such an extent that the stems can push the retaining wall over. Do not build your walls on knotweed without eradicating and disposing of it correctly.
  • Vigorous Japanese knotweed stems can even affect outbuildings, which result in lightweight, insubstantial and poorly founded outbuildings (garden sheds, green houses and even poorly-built garages) being overwhelmed.
  • Greater importance is usually attributed to conservatories by owners, valuers and surveyors, although the effects will be similar to those described for outbuildings.
  • Even well-loved gardens can be ruined by Japanese knotweed due to the invasive nature of the plant.

Wherever you might have found Japanese knotweed growing, the solution is to excavate and dispose of the waste correctly.
