Noxious and Invasive weed control

The Weeds Act specifies five injurious weeds: Common Ragwort, Spear Thistle, Creeping or Field Thistle, Broad Leaved Dock and Curled Dock. Under the Weeds Act 1959 the Secretary of State may serve an enforcement notice on the occupier of land on which injurious weeds are growing, requiring the occupier to take action to prevent their spread. Enforcement of the Weeds Act is carried out by Natural England on Defra’s behalf. Contact us for more help in dealing with these weeds for you


The 5 weeds under this act are explained in more detail here:

  • common ragwort
  • spear thistle
  • creeping or field thistle
  • curled dock
  • broad-leaved dock


Reporting harmful weeds

It isn’t an offence to have harmful weeds growing on your land. However, they mustn’t be allowed to spread to agricultural land, particularly land used for grazing horses and other livestock, or land used to produce animal feed. Natural England may issue enforcement notices to prevent the spread of harmful weeds to these types of land.

If you suspect harmful weeds are on land near you, you should try to contact the landowner to tell them the problem. If this doesn’t work, contact:

  • Natural England, if the weeds are threatening land used for livestock or agriculture (you will need to fill in a complaint form)
  • the Highways Agency for verges of large main roads (trunk roads) or motorways
  • your local council for all other roadside grass verges or council owned land
  • Network Rail for railway land or embankments

Japanese Knotweed

Japanese Knotweed seems to be one of the most problematic invasive species at present. We have dealt with hundreds of cases of knotweed in as many diferent scenarios.  The main problem is it seems to grow through anything, it will certainly push up through tarmac and hardcore, and probably through thin layers of poor or cracked concrete, however it will not grow through a properley constructed slab of concrete. it may grow through the joins of slabs or from around the edges but not through it. Knotweed outgrows our native species thus creating large clumps which will grow larger and spread further the longer you leave it.


One thing we will not do is guarantee eradication, and my advice is to be sceptical of companies offering such guarantees, unless they are completeley removing it off site by digging a hole up to 5 metres deep and upto 8 metres from the crown, then knotweed is nigh on impossible to eradicate in the short term.


Patience, timing and application techniques are key to managing knotweed, there is no quick fix, unless you excavate as described above.


Contact us first for all knotweed problems, we will visit your site and talk you through the eradication procedures we have developed over a number of years.



Giant Hogweed


Scientific name: Heracleum mantegazzianum


Native to:Caucasus mountains in south west Russia and Georgia


Habitat:Widespread, most common on river banks


Easy to identify when fully grown by height, size of leaves and size of flowers. Can be confused with native hogweed when not fully grown or when growth is stunted (e.g. regrowth after cutting).

 Introduced as an ornamental. First recorded wild in the UK in the late 19th century. Spreads solely by seeds, mainly through deliberate planting, wind dispersal and in water courses. Now common across much of the UK. Contact with any part of this plant must be avoided as even minute amounts of sap can cause blistering of the skin following exposure to sunlight. Other negative impacts include out-competing native flora, river bank erosion and increase in flood risk. Can cause delays/ additional costs on development sites where the plant must be removed as controlled waste in order to comply with legislation.


Giant hogweed is listed under Schedule 9 to the Wildlife and Countryside Act 1981 with respect to England, Wales and Scotland. As such it is an offence to plant or otherwise cause this species to grow in the wild.

 Under the Environmental Protection Act 1990, giant hogweed is also classified as controlled waste.

Himalayan Balsam

Himalayan balsam grows fast and can reach two to three metres in height. It rapidly spreads on the banks of slow-moving watercourses and becomes dominant, stopping other plants growing. This plant is becoming more of a problem as it also out grows our native species. A planned approach to eradication can easily deal with this problem weed.  Please contact us for more information or a site visit.
