The roots, or rhizomes are thick and can penetrate up to 3 metres deep and in a 7 metre radius from each stem. They're orange-yellow in colour.

You may notice tall brown canes from dead plants - the plant dies back during the winter but the rhizomes ensure renewed growth each year.

Herbicide

The herbicides used are designed to damage and control the knotweed without causing damage to your property or land.

Although Dig and Dump is the quickest method for removal of Knotweed it is environmentally unfriendly and expensive.

Dig and Dump

Site Capping is a fast way to eradicate Japanese Knotweed while keeping volumes of waste to a minimum.

Our Treatment Services

Dig and Cell Burial

Dig and Cell Burial is ideal if you have enough space on your land for the knotweed waste to be relocated.

Residential Excavation

This would depend upon access to the infected area and boundary fences. Quicker than herbicide but is not always possible.
