What this job actually involves

Knotweed on building plots — how it works here

Knotweed on building plots in Runcorn

On cleared industrial land, canalside plots and redeveloped sites, a stand found after groundworks begin is an expensive surprise. A survey before the dig lets treatment, excavation or on-site burial be built into the programme, with a method statement for the contractor.

Questions about knotweed on building plots

Will planners ask about knotweed?
Some applications require invasive plants to be identified, and a survey report covers that.
How do I know if it is Japanese knotweed?
Look at the stem first: hollow like bamboo, speckled with purple, and zig-zagging with a node at each bend. Leaves are broad with a flat base. Small cream flowers appear in late summer and the dead canes stay brown through winter. A photo sent to us is quicker than guessing.
Is it illegal to have knotweed in my garden?
Having it is not an offence. Letting it spread into the wild is, and any cut material counts as controlled waste. If it crosses onto a neighbour's land you could face a claim.
Will knotweed stop me getting a mortgage?
Not on its own. Most lenders will lend against a professional survey, a treatment plan and a guarantee that transfers to the buyer.
How long does treatment take?
Spraying usually runs over three to five growing seasons followed by monitoring. Excavation takes days but costs more.
Can I just dig it out myself?
We advise against it. Tiny pieces of rhizome regrow, and the soil cannot go in a skip or the garden waste bin without proper handling.
