Herbicide treatment over several seasons, with return visits.
Free photo ID check · Mon–Fri 8am–6pm, Sat mornings
For most gardens, spraying is the practical answer. It is carried out through the growing season and repeated for three to five years until nothing comes back, followed by monitoring. It is cheaper and less disruptive than digging, unless a sale or building schedule forces the pace.
Treatment follows the plant's growth rather than the calendar. Visits generally begin once the canes carry a full canopy of leaves, because the herbicide travels down into the roots while the plant is feeding them. A second round follows later in the season, and an autumn visit may be used before dieback. In winter the stand looks dead, but the roots are still alive underground, so the programme continues into later years.
Weather matters. Rain soon after spraying can wash the product off, and strong wind risks drift onto plants you want to keep. Dense neighbouring growth can block access to the canes. Where a bank runs beside water or a drain, only suitable products may be used and some sites need permission first, so tell us if your boundary is close to either. Returning visits are logged so progress is clear.
Do not cut, strim, mow or pull the plant, even if it looks dead, because disturbing it can undo months of work. Keep children and pets away from freshly treated stems for as long as the product label says. Photograph the stand each month so progress can be compared. Do not move soil from the area. Keep each treatment record and the final sign-off somewhere safe, as a buyer or lender may ask for them.
