Weed control

Weed treatment programme 2017

Treatment involves the application of glysophate to the weeds present on roads, pavements, and tree pits (young staked trees are maintained separately).

Generally, noticeable dieback of weeds happen within 14 days of the treatment taking place. 

The latest weed treatment programme (PDF) is for June 2017 but may alter due to  weather conditions.

Weed control on streets

The council's Street Cleansing team is responsible for the control of weeds on streets including around established trees, this is done by an external contractor, but is managed and coordinated by the Street Cleansing team. 

Weeds are treated between two and three times per year (spring, summer and late autumn) depending on growing conditions.

Weed control around street trees

The control and management of weeds around established trees is carried out at the same time as the treatment of weeds on streets.

Weeds in young tree pits are cleared by hand only, no chemicals are used for our young trees and mulch is applied to the bed.  Newly planted trees are watered for the first 2 years and weeds are removed on first and last watering visit each year.

Young trees are determined as trees that are still staked and guarded. Once this is removed, the trees are then classed as established trees.

Invasive plant control

The Council has a legal responsibility to control invasive plant species on its land such as Japanese Knotweed, Giant Hogweed and Himalayan Balsam. Glyphosate is the only proven and effective control mechanism for Japanese Knotweed and Giant Hogweed.

The treatment of these species is targeted and must be completed on a cyclical basis in order to manage the spread of these invasive species.

Weed control of shrub beds on streets, housing estates, parks, open spaces (including sports courts)

The control of weeds in shrub beds and sports court hard surfaces is limited to targeted control in order to ensure the use of chemicals is kept to a minimum.  A maximum of two applications are undertaken in spring and then mid to late summer.

Pesticides and herbicides

We and our nominated contractors use glyphosate primarily to control weeds on pavements, paths, kerb edges, sports courts, and shrub beds on streets, housing estates and in parks and open spaces. 

These chemicals are fully compliant with legislative requirements and a full COSHH (Control Of Substance Hazardous to Health) assessment is undertaken by the service prior to any use.

The EU Commission adopted an 18 month extension of the current approval of glyphosate on 21 June 2016 until the European Chemical Agency (ECHA) has concluded its review.

We're always seeking to minimise the use of pesticides and herbicides and is investigating alternative solutions for the management and control of weeds with neighbouring local authorities and the wider industry.  However at this time trials have not proven to deliver the same output on the ground within the same resource constraints.
