Hi there, I have a mature planted bank at the front, but have a few persistant dock leaves and briars and grass that keep growing through, how can I treat these successfully without killing the shrubs. Don’t know the name of the shrub, evergreen with purple berries. Thank you.
There are two weedkillers that may be used. Roundup will kill any green vegetation, in the correct dose, but you must nbot allow it onto the shrubs, or Casoron can be used in mid-winter only.
