Japanese Knotweed: Why Professional Removal Matters

Japanese Knotweed (Fallopia japonica) is one of the UK’s most invasive plants. Known for its rapid growth and aggressive root system, it can damage structures, overwhelm native habitats, and reduce property values. Once established, it can be extremely difficult to remove without specialist help.

How Japanese Knotweed Reached the UK

Originally introduced to Britain in the 19th century as an ornamental plant and for stabilising railway embankments, Japanese Knotweed was admired for its bamboo-like stems and heart-shaped leaves.

However, its fast-growing underground rhizomes quickly made it a problem. These roots can spread several metres and even push through tarmac, paving, and building foundations. Today, Knotweed is found across the UK and is listed under Schedule 9 of the Wildlife and Countryside Act 1981, making it illegal to plant or cause it to spread in the wild.

 

Why It’s a Problem in North Devon and West Somerset

Japanese Knotweed poses serious risks for homeowners and the environment:

  • Structural damage – Rhizomes can break through paving, walls, and drains.
  • Legal and financial issues – Its presence must be declared when selling a property and can lower value.
  • Rapid spread – Even a small fragment of rhizome can regrow into a new plant.
  • Environmental harm – Knotweed outcompetes native plants, reducing biodiversity along riversides, woodlands, and gardens.


How to Remove Japanese Knotweed

Removing Japanese Knotweed is complex and best left to professionals. Common control methods include:

1. Herbicide Treatment
A glyphosate-based herbicide, applied by trained professionals, can gradually control and kill Knotweed. Treatment usually requires multiple applications over several growing seasons.

2. Excavation and Disposal
For faster results, mechanical excavation may be used. Knotweed waste is classed as controlled waste and must be taken to a licensed facility; it can never be disposed of in standard green waste.

3. Root Barriers and Containment
On development sites, root barriers can be installed to prevent rhizome spread. Ongoing monitoring is essential to ensure success.

American Skunk Cabbage in North Devon and West Somerset

American Skunk Cabbage (Lysichiton americanus) was introduced to the UK in the early 20th century as a decorative water garden plant. Unfortunately, it escaped cultivation and spread through rivers and wetlands, where it now competes with native flora.

Why It’s a Problem

  • Outcompetes native species – Large leaves block sunlight from marsh marigolds and sedges.
  • Disrupts ecosystems – It alters wetland habitats, threatening rare plants.
  • Spreads rapidly – Each plant produces thousands of seeds, and rhizomes enable regrowth even after cutting.
  • Difficult to remove – Once established, it’s extremely persistent.

The species is listed under Schedule 9 of the Wildlife and Countryside Act, meaning it’s illegal to plant or cause its spread in the wild.

How to Remove American Skunk Cabbage

1. Manual Removal
Suitable for small patches. Plants must be dug up completely, including the rhizomes, and disposed of via licensed waste facilities.

2. Repeated Cutting
Regular cutting weakens plants but won’t kill roots—this method requires consistency.

3. Professional Herbicide Application
In sensitive or large areas, glyphosate may be applied under licence by qualified specialists.

4. Long-Term Monitoring
Even after removal, seeds may germinate years later. Ongoing checks are essential.
