Most residential roads in Warrington are treated twice a year, once in the spring and once in mid-summer, with a third application later in the year if necessary. 

The treatments are timed to coincide with weed growth for maximum control. However the treatments are weather dependent, and in times of adverse weather, our programme may be delayed. 

Our weeding schedule

This year's schedule:

  • First treatment – started Monday 19 April 2021

  • Second treatment – scheduled for mid-July

  • Third treatment – scheduled for the end of September/beginning of October (provisional)

We'll keep you updated on our treatment progress throughout the year. 

Each treatment takes between two to three weeks to complete and there is a die-off period of up to 21 days after each treatment.

Please note: It's not possible to treat areas where there are no weeds present, as legislation only allows a targeted approach to treat those present at the time of application.
