Rhododendron ponticum Control in Scotland

How the works run

1. 1Photo surveyFree initial assessment from your photos, usually within 24 hours.
2. 2On-site surveyA surveyor attends from £250 to map stand density, terrain and proximity to ramorum-susceptible species.
3. 3Method planA written plan setting out cut-and-stump-treat, stem injection or foliar spray by area, with a phased multi-year price for large stands.
4. 4Clearance & treatmentManual and mechanised clearance followed by herbicide treatment to prevent regrowth from cut stumps.
5. 5Follow-up monitoringReturn visits to treat regrowth and seedlings, since rhododendron seed banks can persist for years.

Why rhododendron matters to Scotland's rainforest

Scotland's Atlantic oakwoods, a fragment of the internationally rare temperate rainforest habitat found along the west coast from Argyll to Wester Ross, are being progressively shaded out by Rhododendron ponticum, introduced as an ornamental and game cover plant in the eighteenth and nineteenth centuries. Left uncontrolled it forms a dense evergreen canopy that blocks light to the mosses, lichens and liverworts that make these woodlands internationally important, and prevents oak and hazel seedlings establishing.

The Phytophthora ramorum connection

Rhododendron ponticum is a highly effective host for Phytophthora ramorum, the pathogen responsible for widespread larch disease and felling across Scotland and Wales. Because infected rhododendron can carry high spore loads without showing obvious symptoms, clearing it near larch stands and other susceptible species is now a recognised part of biosecurity management, and we follow boot and tool washdown protocols between sites to avoid spreading the pathogen ourselves.
