We carry out three treatments a year to treat weeds that grow up in small gaps on the highway/ pavements. These are carried out on a borough wide basis usually in Spring Summer and early Autumn.
We schedule the spray treatments taking into account the weather conditions as the effectiveness of the spray is affected by rainfall which can dilute it.
Each boroughwide spray takes about four to five weeks to complete and once sprayed ‘dieback’ of the weeds should occur within seven to ten days under normal conditions.
Residue from the weeds is removed through routine scheduled street cleaning.
Particularly resilient weeds may require special attention which will be assessed on a case by case basis.
Japanese knotweed is a highly invasive weed. It and can grow through walls tarmac and concrete damaging buildings and roads.
We cannot help if knotweed is growing on private land, more information and advice on managing and disposing of Japanese Knotweed and other invasive weeds is available on the GOV.UK website.
