Still not sure what’s growing?

We also treat other invasive species and nuisance weeds. There are a large number of native and non-native plants in the UK that are known to be invasive. Other invasive weeds can cause environmental damage and tend to be one of the biggest threats to native plants and animals.

Here’s some information on some of the invasive species that we can help with. If you have an overgrown garden area or green space surrounding your property, get in touch!

Himalayan Balsam

At around 2 metres tall, this plant is normally found along watercourses, grows in dense patches, and outgrows other vegetation. Left untreated, it can take over large areas of ground within a few years.


A large evergreen shrub with a large pink flower. They severely impact the biodiversity of an area by reducing worms, birds, and other plants. They also impact the regenerative ability of a site.

Horse Tail

Also known as Cwt-y-Cadno, this annual plant grows up to 1.5 metres. Native to the British Isles, it’s becoming more of a nuisance due to the damage it causes to concrete or asphalt.


Seen on most waste patches of land. The easily-spread seeds cause large-scale populations, and the shrub out-competes the native vegetation. The plant can damage walls as the wind-blown seeds germinate in mortar.

Japanese Knotweed

Japanese Knotweed spreads quickly when disturbed and is difficult to eradicate when poorly treated. This has dense clumps, zig-zag purple speckled stems, and is striking green.

Giant Hogweed

With the potential to grow up to 5 metres tall, these are identifiable due to their sheer size.  You will commonly spot giant hogweeds in hedgerows. If found, take care as contact with the sap can severely blister skin.
