Council works to remove invasive weed from Watford

Areas in Watford affected by the invasive Japanese knotweed will be fenced off shortly, by Watford Borough Council, so that it can start to remove it from the town.

Japanese knotweed is listed by the World Conservation Union as one of the world's worst invasive species. The invasive root system and strong growth can damage concrete foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites.

A number of areas with Japanese Knotweed have been found on land managed by the council, including public open spaces, rights of way, housing properties and some industrial areas. Some of these areas will be fenced off in the coming weeks ready for treatment works to begin in the spring 2016.

The most cost effective method of treatment is by herbicide application, consisting of several visits through the growing season for two to three seasons. The herbicide will be carefully applied and will not have any adverse effects to local wildlife or the surrounding area.

Elected Mayor, Dorothy Thornhill, said: ‘As all gardeners will recognise, Japanese knotweed is horrible stuff. This treatment programme will ensure we are as weed-free as we can be for the next 10-15 years.’
