What is Japanese Knotweed?

Japanese Knotweed (Fallopia japonica) is a highly invasive plant which was introduced to this country as a quick-growing ornamental plant. It has now become a well documented problem.

Our main course of action for the eradication and removal of Japanese Knotweed is the stem injection method, where a measured dose of glyphosate is injected directly into the plant. There are several advantages to this technique:

  • Target specific;
  • No herbicide damage to the surrounding area;
  • Very effective;
  • No spray drift;
  • Also effective against Giant Hogweed.

This year we are undertaking a Knotweed eradication and disposal project on behalf of the Norfolk Broads Authority.
