How we work in Bishopston, Pennard & South Gower villages
- Free initial quote from your photos to help confirm it is montbretia
- Map the stand and its edges before work starts
- Contain roots, seed and soil so it can't spread
- Use the lightest method that works, with precise herbicide only where it is the safer option
- Return visits and written records until regrowth stops
