What this job actually involves

Knotweed from next door — how it works here

Knotweed from next door in Bolton

Knotweed coming from a void house, a rental, a cleared mill site or a canal bank is one of the commonest reasons Bolton households get in touch. The survey notes the stand, the place it crosses the boundary and the likely route. You can take that evidence to the owner, and a barrier can protect your side meanwhile.

When knotweed arrives from over the fence

Begin with dated photographs and a survey. Between them they show where the stand starts, how far it has crossed and when you first reported it. Keep every message with the neighbour or landlord. If things ever become formal, a clear run of dates counts for more than recollections.

Many owners have no idea the plant is there. A polite letter with a copy of the survey often does the job. For empty houses and cleared sites, a Land Registry search can help find the owner, and the council may be able to step in where a property has been abandoned.

While the source is being sorted, treating your own patch and fitting a barrier along the boundary can stop things getting worse. A barrier does not kill the plant, but it keeps your garden usable and shows you took sensible steps.

Questions about knotweed from next door

What if the owner will not do anything?
Allowing knotweed to spread onto someone else's land can amount to a nuisance. Keep the report and get legal advice if talking fails.
How do I know if it is Japanese knotweed?
Start with the stem: hollow like bamboo, flecked purple and bending in a zig-zag at every joint. The leaves are shield-shaped with a flat edge where the stalk joins, and in late summer it throws up sprays of cream flowers. Old brown canes can stand through the whole winter. Sending us a photo is quicker than comparing pictures on your phone.
Is it illegal to have knotweed in my garden?
No, owning land with knotweed on it is not an offence. The law is broken if you let it spread into the wild, and soil or cuttings count as controlled waste. If it moves into a neighbour's garden, they may be entitled to bring a claim against you.
Will knotweed stop me getting a mortgage?
It does not rule one out. Plenty of lenders will go ahead if there is a professional survey, a treatment plan and an insurance-backed guarantee that can pass to the buyer.
How long does treatment take?
Most spraying programmes run for three to five growing seasons, with monitoring afterwards. Digging it out takes days rather than years, but the bill is a good deal higher.
Can I just dig it out myself?
We would not. Small fragments of rhizome regrow, and the soil cannot go in your wheelie bin or be taken to the household waste site.
