The main controls by contractors Phlorum were completed in 2018, but they are contracted to come back until Japanese Knotweed has gone from specified Watford BC areas, they said they want to leave bonsai regrowth (which is present at a few points at Knutsford Playing Fields) till it comes back properly, and then they will hit it again.
