Site Assessment and Survey
We will visit and walk over the entire site, checking boundaries and if possible adjacent properties. We will visit all types of sites including; private property, brown field, commercial and industrial. To give an accurate quote for the eradication of Japanese knotweed or any invasive weed a site assessment and survey is required.
As part of the survey we will include:
- A site plan and photos – identifying where the Japanese knotweed or other invasive weed is situated.
- Inspection of the surrounding area.
- History of past treatments and current maintenance schedules.
- How development plans would affect the treatment.
- Risk assessments including biological, health & safety and financial.

Invasive plant management plan
After a discussion with you the client we will design a plan for the management or eradication of the Japanese knotweed.
It will contain:
- The objectives of the management.
- An evaluation of control options (if applicable and will be influenced by proposed use of land).
- A detailed description of the control actions to be taken.
- An assessment of the risks associated with any control actions.
- A description of how the success of the control action will be evaluated.
- Advice on how to prevent additional Japanese knotweed arriving on site.
- A treatment schedule.
- A full breakdown of costs associated with the control action.

Treatment
There are usually four main treatment methods of dealing with the Japanese knotweed:
Herbicide Treatment
This is our preferred method of dealing with the invasive weed. The best time for Japanese knotweed to be sprayed is late summer from flowering onwards.
