Bristol and the wider Somerset area are among the worst-affected regions for Japanese knotweed in the UK. The River Avon and its network of streams, railway embankments, and Victorian housing stock have given the plant decades to spread. If you have spotted suspicious red-tinged shoots or dense bamboo-like canes on your property, Conservation Land Services can help you deal with it quickly, discreetly and in a way that satisfies mortgage lenders.
Local Japanese knotweed specialists you can trust
We are a nationwide invasive weed control company with deep roots in the South West. Our work is led by Robert Mitchell, a Property Care Association (PCA) Certificated Surveyor in Japanese Knotweed (CSJK), Chair of the PCA Invasive Weeds Group and an examiner for the CSJK qualification. When you work with us you are dealing with one of the people who helps set the standard for the industry, not a call centre.
Why Bristol gardens are so badly affected
Japanese knotweed thrives along watercourses and disturbed ground, and Bristol has plenty of both. Fragments of rhizome as small as a fingernail can regrow, so it spreads easily through fly-tipped soil, shared garden boundaries and riverbanks. Left untreated it can affect drains, hard surfaces and boundary walls, and, crucially, it can stop a house sale in its tracks. You can read more in our case study on knotweed taking over Bristol gardens.
Our service in Bristol & Somerset
We offer a complete, joined-up service:
- Free photo identification, send a clear close-up using our invasive weed checker and we will tell you whether it is knotweed or a harmless lookalike.
- Site survey and report, an on-site inspection (in an unmarked van, so neighbours need not know), followed by a clear written report and management plan.
- Treatment and removal, herbicide treatment programmes or full excavation, depending on what your situation and timescale require.
- 10-year insurance-backed guarantee, the documentation mortgage providers need to lend on an affected property.
Buying or selling a property in Bristol?
Most of our residential enquiries are tied to a property transaction. If knotweed has been flagged in a survey, a recognised management plan with an insurance-backed guarantee usually allows the sale and mortgage to proceed. Learn more about our residential services, or if you manage commercial land or a development site, see our commercial services.
