Applied weed control services 

Through a carefully planned herbicide application strategy, Twig’s weed control service allows for an optimised ground care solution to be delivered, in consideration of the effects of climate change. As part of a grounds maintenance contract, Twig’s weed control services ensure that our client’s grounds are well presented and reduce the risk associated with a diminished property value caused by invasive non-nature weeds.

Twig can control the growth of algae, lichens, liverworts and moss will all grow on hard surfaces however, contrary to popular belief, they do not damage what they are growing on but can cause these surfaces (patios, drives, paths and steps) to become slippery, presenting a potential hazard to health.

Comprehensive weed control solution for invasive weeds

Invasive weeds are destructive and need professional attention quickly. Twig’s ground maintenance teams are fully equipped and trained in managing and eradicating dangerous invasive weeds. Invasive weed species include:

  • Japanese Knotweed
    Originally introduced as an ornamental plant, this highly invasive weed species has proved to be a costly menace. Spreading with relative ease it prevents native vegetation from growing and can even push its way through foundations, concrete and tarmac.
  • Himalayan Balsam 
    Introduced to the UK in 1839, Himalayan balsam (Impatiens glandulifera), a relative of the busy Lizzie,  has now become a naturalised plant. It reaches well over head height, growing 2 to 3 metres in height, and is a major weed problem, especially on riverbanks and wasteland.
  • Giant Hogweed
    Giant hogweed (Heracleum mantegazzianum) is a close relative of cow parsley and originates from Southern Russia and Georgia. It can reach over 3m (10ft) in height and although it is an impressive sight when fully grown, giant hogweed is invasive and potentially harmful due to chemicals in the sap which can cause photodermatitis or photosensitivity.
  • Rhodendron Ponticum
    Rhododendron ponticum (L.) is a non-indigenous evergreen shrub belonging to the Ericaceae family and was introduced to the UK in 1763.  Although it possesses attractive flowers, the Rhododendron can have quite a negative impact on an invaded site. According to Forest Research, “it has been shown to reduce the numbers of earthworms, birds and plants and regenerative capacity of a site, leading to a reduction in the biodiversity of the area”.
