Act quickly. Japanese knotweed spreads rapidly and can grow from a fragment of root as small as 0.7g. Early treatment is significantly cheaper than treating an established infestation. If you suspect knotweed, contact us for a free identification visit.
How to Identify Japanese Knotweed
Japanese knotweed (Reynoutria japonica) is one of the UK's most invasive plants. It was introduced as an ornamental plant in the 19th century and has no natural predators in the UK. It spreads through its underground rhizome network, which can extend 7 metres horizontally and 3 metres deep.
- Bamboo-like hollow stems with purple/red speckles
- Shovel-shaped leaves up to 120mm wide in a zig-zag pattern
- Dense stands growing 2–3 metres tall by midsummer
- Creamy-white flowers in late summer (August–September)
- Dead brown canes persisting through winter
- Rapid regrowth from tiny root fragments in spring

Why You Must Act
Property Damage
Rhizomes penetrate foundations, drains, tarmac, and block paving. Can cause structural damage to buildings and hard landscaping.
Mortgage Issues
Most UK mortgage lenders require a professional management plan before approving a mortgage on a property with knotweed within 7 metres of a structure.
Legal Liability
Allowing knotweed to spread onto neighbouring land is a civil offence. You can be prosecuted under the Wildlife & Countryside Act 1981 if it spreads to the wild.
Property Value
Untreated knotweed can reduce property value by 5–15% and make a property difficult or impossible to sell.
Waste Regulations
Japanese knotweed is classified as controlled waste under the Environmental Protection Act 1990. It must be disposed of at a licensed facility — you cannot compost it or take it to a household tip.
Treatment Options
We assess each infestation individually and recommend the most appropriate treatment. In many cases, a combination of methods is the most effective approach.
Herbicide Treatment Programme
The most common and cost-effective approach. Professional-grade herbicide (glyphosate-based) is applied to the foliage in late summer when the plant is translocating nutrients to the roots. Typically requires 3–4 treatments over 2–3 seasons for full eradication. We provide a management plan accepted by most mortgage lenders.
Excavation & Removal
Physical excavation of the rhizome mass and contaminated soil. All material is classified as controlled waste and must be taken to a licensed landfill. Effective but expensive for large infestations. Often combined with herbicide treatment for residual rhizomes.
Root Barrier Installation
High-density polyethylene root barriers installed to contain the spread of rhizomes. Used where excavation is not practical (e.g. adjacent to buildings or boundaries). Typically combined with herbicide treatment.
Dig & Bury (On-Site)
Excavation and burial of contaminated soil on-site at a depth of 5 metres or more. Requires specialist equipment and a site waste management plan. Suitable for large sites where removal is not practical.
Mortgage-Lender-Accepted Management Plans
If you are buying or selling a property with Japanese knotweed, your mortgage lender will almost certainly require a professional management plan from a qualified contractor. We provide management plans in a format accepted by most major UK lenders, including Nationwide, Halifax, Barclays, HSBC, and Lloyds.
Our plans include a site survey report, photographic evidence, a treatment schedule, and a completion certificate on eradication. We also provide insurance-backed guarantees where required.
