What this job actually involves

Knotweed root barrier — how it works here

Knotweed root barrier in Salford

A root barrier is a heavy-duty membrane set upright in a trench along a boundary or around a structure. It suits cases where the stand is on the far side of a wall and cannot be treated from your land, or where new work needs protecting. It blocks the rhizome at the line; the stand itself still needs dealing with.

Questions about knotweed root barrier

How deep is it set?
Usually about a metre or deeper, depending on the soil and what is being protected.
How do I know if it is Japanese knotweed?
Look at the stem: it is hollow like bamboo, flecked with purple and grows in a zig-zag, with a node at each bend. Leaves are shield-shaped with a flat base. Late summer brings creamy flower sprays, and in winter you are left with brown, brittle canes. The fastest check is to send us a photo.
Is it illegal to have knotweed in my garden?
No, owning it is not an offence. Letting it spread into the wild is, and the waste has to be handled as controlled waste. If it crosses onto a neighbour's land you could face a claim.
Will knotweed stop me getting a mortgage?
It does not have to. Lenders mostly want to see a survey, a treatment plan and an insurance-backed guarantee that can pass to the next owner.
How long does treatment take?
A spraying programme normally runs three to five growing seasons and is then monitored. Excavation takes days, but costs more.
Can I just dig it out myself?
It is a poor idea. Small fragments of rhizome regrow, and the soil you lift cannot go in a skip or the green bin without proper handling.
