To carry out this Japanese Knotweed eradication in London, we sprayed and injected it with a herbicide. We had to choose a chemical that was not going to harm the tenant’s dog as he was allowed to roam freely in the garden. The chemicals were safe for the tenant’s dog but was lethal for Japanese knotweed in the London garden, as can be seen by the pictures.

The soil that was excavated was carefully checked for rhizomes. In coordination with the chemical treatment less than half of what we expected to be excavated was classed as contaminated soil bringing down the excavation cost hugely. This left a very happy client in London with no Japanese knotweed. He could now also proceed with his double basement extension.
