Invasive weeds - Invasive weeds management and weed removal UK

We offer commercial weed removal of invasive weeds across UK

The Oxford dictionary defines a weed as:

A wild plant growing where it is not wanted and in competition with cultivated plants”


The Nature Conservation Minister has announced initiatives to crackdown on the illegal introduction of alien plants into this country - but is this too little too late?

Many voracious plants are already here and causing major problems. Their control and eradication needs to be carefully planned, monitored and managed to ensure the existing situation of their overpowering invasion is met full on and stemmed.

Many of these plants were introduced in Victorian times with no idea that these foreign plants might escape over the garden wall. Japanese Knotweed is proving to be one of the most pernicious, non-native species, with an estimated clean-up bill in excess of £1.56 billion; with all these other weeds increasing exponentially, the clean-up bill for problem weeds in total is likely to be significantly higher.

This website deals with both invasive and injurious weeds in the UK.

Invasive Weeds

Non-native invasive species are organisms that have been introduced by humans either purposely or by accident and that have become serious environmental pests. One reason for their success as pests is that they are typically introduced without the array of associated natural controls (herbivores, parasites, pathogens, predators) that occur in their native range. In addition to the great loss of biodiversity, habitat degradation and other ecological consequences, invasive species cause huge economic damages valued in millions of pounds annually and some pose a human health threat.

Invasive alien plants threaten native species and habitats by competing for critical and often limited resources like sunlight, water, nutrients, soil and space. They succeed through vigorous growth, prolific reproductive capabilities and by causing changes that favour their growth and spread. Invasive plant species displace alternative plant communities, impede forest regeneration and natural succession, change
soil chemistry, alter hydrologic conditions, cause genetic changes in native plant relatives through hybridization and some serve as agents for the transmission of harmful plant pathogens.

It is illegal to plant Japanese Knotweed and Giant Hogweed which strangle and suffocate other plants, but a ban on many others is also needed - plants such as:

  • Himalayan Balsam
  • Floating Pennywort
  • Crassula helmsii
  • Azolla filiculoides and
  • Rhododendron ponticum


Injurious Weeds

The weeds act 1959 consolidates earlier legislation concerned with commercial food production and applies throughout Great Britain. The Act empowers the respective Agriculture Ministers to serve notice requiring an occupier of land on which certain specified weeds are growing to take action to prevent the weeds from spreading. 

The Act applies to five injurious weeds, which are considered to be a potentially serious threat to agricultural production. These are:

    • Spear thistle (Cirsium vulgare)
    • Creeping or field thistle (Cirsium arvense)
    • Curled dock (Rumex crispus)
    • Broad-leaved dock (Rumex obtusifolius)
    • Common ragwort (Senecio jacobaea)
