WHAT WE DO

At Tree Fella we have developed a number of treatments and techniques to deal with Japanese Knotweed and other invasive plants.

 

We have, developed methods and systems based on attention to detail and a combination of controls available which are proven to work. We also have a total commitment to complete long term eradication on every site. Our highly trained surveyors and operatives are experienced in methods to eradicate these invasive species and will provide an efficient and effective service, in line with Environmental Agency guidelines.

Tree Fella provide solutions to home owners, land owners, property developers, local authorities etc.

We aim to provide our customers with best advice and cost effective solution bespoke to their property or site enabling the  eradication of the Japanese Knotweed (or other invasive species).

We provide the following:

  • Site Surveys

  • Site Assessment Reports

  • Mortgage Reports

  • Invasive Species Management Plans

  • Invasive Species Eradication Programmes

    • Herbicide Spray

    • Excavation & removal

    • Barrier

    • Soil Screening

  • Trained operatives

  • Necessary Equipment

  • Monitoring and maintenance post works, on all projects

 

Herbicide Treatment

The use of herbicide is the most efficient and cost effective option for the treatment of Japanese Knotweed.

Used alone or in conjunction with our other treatments plans, the herbicide reaches both the growth on the tall Japanese Knotweed foliage and the root system that can grow significantly from the crown of the plant.

A herbicide treatment and removal option can take 1 – 4 growing seasons to be 100% effective depending on the Japanese Knotweed issue and herbicide used

Our operatives our qualified in the application of chemicals.

Consideration of Herbicide Treatment- This may not be suitable if near a waterway

 

 

Excavation & Removal

This treatment is ideally suited to new build schemes and construction projects. It can alleviate the time constraints of most building projects by utilising plant machinery to excavate the infected soil and either disposed of on site in a controlled process or complete removal to a licensed landfill site. A surveyor will inspect the site and assess the best course of action.

 

 

Root Barrier

The root barrier consists of a membrane that limits the spread of the plant or can be used to protect the built environment from damage. It can be used to prevent spreading onto neighbouring land and affecting neighbouring property. It is very useful in preventing legal issues and helps stop the spread of the plant. This is purely a control measure but can control the spread whilst herbicide application is used to eradicate the stands. It is often used in conjunction with one of our other treatment options.

 

Soil Screening

Contaminated soils can be dug out and put through a trommel screen, and picking station with large pieces of rhizome thus being removed and taken to a licensed site for disposal, any small pieces of rhizome that are missed will grow but due to the lack of rhizome mass will be easier to kill with a future herbicide application. This option is suitable for sites that may have time limit for eradication purposes i.e construction sites. This is a very good option if The Japanese Knotweed  has infected hardcore heaps spoil heaps, or hardcore yards.

Cell Burial

This option provides a solution appropriate for the timescale of each individual
development. Japanese Knotweed onsite burial is a fast cost effective method of dealing with Japanese Knotweed infestations. The constraints to this methodology are site size, water levels and area of development. Within the cell burial programme a pit is dug and lined with a geotextile membrane. All joints within the cell are welded closed. The Japanese Knotweed is then excavated under the direction of our highly experienced managers.


This is then capped with a cover of geotextile membrane and welded shut, thus creating "The Cell". A cover of soil is then placed on top of the cell to a depth of approximately 2 metres. This solution is perfect for areas of sites that are not to be piled or built on. Historically clients have built car parks on top of the cells.
