Weed control

About the weed treatment programme for 2017 and how weeds alongside roads are treated and managed in your area.

Weed growth can affect the safety of road users by damaging surfaces of roads and pavements and reducing available road and pavement widths.

They can disrupt drainage, obstruct pedestrians and appear unsightly.

The following table sets out our standards for treating weeds:


Generally twice a year, carried out in the spring and late summer using a systemic weed killer, but with an additional mid-season treatment when growth conditions require.

Noxious Weeds

Where a problem is identified a one-off treatment, or series of treatments, will be arranged.

Injurious Weeds

The Weeds Act 1959 applies to the following injurious weeds:

  • broad leaf dock
  • common ragwort
  • creeping or field thistle
  • curled dock
  • spear thistle

Where harmful weeds have been identified, Notice may be served upon the occupier of the land requiring them to take action to prevent these weeds from spreading.

For more information on preventing the spread of ragwort to land used for grazing horses or livestock, land used for forage production and other agricultural activities, please read the Defra Code of Practice.

The Wildlife and Countryside Act 1981 states that it is an offence to "plant or otherwise cause to grow in the wild" any plant listed in Schedule 9, Part 2 of the Act, which includes giant hog weed and Japanese knot weed.

DEFRA provides guidance that if you have invasive plants or injurious weeds on your premises, you have a responsibility to prevent them spreading into the wild or causing a nuisance.  

Read about Invasive Plants and Injurious Weeds on DEFRA website.


Please note that the below programmes are for guidance only and are subject to change. The programmes show a comparison of the planned weed treatment dates and the actual dates that the works took place. The dates on the actual programme will be plotted following completion.

Suffolk Highways will begin the 2017 weed treatment programme in April 2017 and will continue for six months.  

Except for roads in Ipswich. Contact Ipswich Borough Council about their weed treatment programme.
