Japanese Knot Weed

Japanese knotweed -scientific name: Fallopia Japonica is, without doubt one of our most, feared and vigorously invasive species, it can grow by up to 10cm a day during the summer, forcing itself through walls, tarmac and concrete - hence reducing property values coupled with their inability to attain a mortgage where properties are affected. 

Japanese Knotweed was brought to Britain by the Victorians, who obviously did not realise how destructive it was, when they blithely used it to line our railway tracks and formal gardens.

Unfortunately the treatment to eradicate this noxious plant can take several treatments over a substantial period of time and will require monitoring for regrowth.

We have carried out stem injection treatment for Japanese Knot Weed in conjunction with TFL and have very positive eradication results on this noxious weed.

Ash Dieback

Following the devastation of Elm Disease we now have Ash Disease, commonly known as ash dieback, or Chalara, which is a disease of ash trees caused by a fungus called Hymenoscyphus fraxineus. Chalara causes leaf loss, crown dieback and bark lacerations and once a tree is infected it very often means it will succumb to an unhappy end. Experts believe not all trees will die of the infection - some are likely to have genetic factors which give them tolerance of, or resistance to the disease. Scientists are working hard to learn from existing and emerging research and practical experience in combating the disease.

OPM – Key Facts

Caterpillars of the Oak Processionary Moth are a pest which can be a hazard to the health of oak trees, people and animals. The caterpillars shed their tiny hairs, which can then be blown in the wind causing itchy skin rashes, eye and throat irritations and, sometimes breathing difficulties.

The caterpillars eat the oak leaves and large numbers can defoliate whole trees bare. OPM is a native species of southern Europe which was accidentally introduced to England, leaving our precious oak trees vulnerable.

The greatest risk period is May to July, but nests should always be avoided because they may contain thousands of hairs containing toxins and remaining active for up to 5 years.

We have carried out the removal of OPM in conjunction with Transport for London.
