What we do
A practical way forward.
Understand what is growing, discuss the options and agree the treatment before work begins.
Targeted stem injection
Herbicide delivered directly into suitable knotweed canes. Precise application without airborne spray drift.
Assessment & advice
A review of the visible growth, site conditions and treatment options, with practical advice and a quotation for each treatment.
A more targeted approach
Treat the plant.
Respect the surroundings.
- No spray drift. Injection applies herbicide inside suitable canes.
- Less unintended contact. Targeted delivery reduces direct exposure of surrounding plants, soil and water.
- Selected for the site. Cane size, growth and access inform the method. Foliar treatment is considered where appropriate.
How it works
Clear steps. An agreed price.
Start with your site
Send your location, photographs and an approximate affected area. We can then discuss a site assessment.
Agree the approach
Receive treatment plan advice and a quotation for the proposed treatment, based on the area, access and method.
Carry out the work
Treatment is carried out within the agreed area when plant and site conditions are suitable.
Each treatment is quoted separately. Further treatment may be needed; eradication is not guaranteed.

Think you have found knotweed?
Start with a closer look.
Japanese knotweed commonly has:
- Jointed, bamboo-like stems, often with purple flecks.
- Broad, pointed leaves with a flattened base, arranged alternately along the stem.
- Small creamy-white flower clusters in late summer.
Giant knotweed and hybrids can look different. Send a photograph of the whole plant, a leaf and the stem for an initial discussion.

Useful to know
A few answers.
When can knotweed be treated?
Late summer and autumn are commonly used for herbicide treatment, after flowering begins and before dieback. Suitability depends on the plant’s condition, treatment method and weather. Send recent photographs to discuss your site.
How much does treatment cost?
Each treatment is quoted separately according to the affected area, access and method. The proposed scope and price are agreed before work starts.
Will one treatment be enough?
Further treatment may be needed and would be quoted separately. Reduced or stunted growth does not necessarily mean that the underground rhizomes have died.
What happens to the treated canes?
Treated canes remain in the treatment area and are allowed to naturally decompose on site. Removal of plant material or soil is not part of this service.
Where can I read more about knotweed?
RHS knotweed guidance and the Scottish Invasive Species Initiative explain identification, spread and control.
