In light, workable soils, cut back the scrambling stems to around 30cm (1ft) from ground level. Strimmers will deal effectively with large areas of woody weeds.
Dig out the bramble stump, taking the roots away at the same time. It is important to remove as much of the below-ground parts as possible, as brambles have the ability to regenerate from well below soil level. Seedlings should be weeded out by hand.
Cut back all long, trailing stems to within 20-30cm (8in-1ft) of soil level, then take them away to a suitable place and burn them. Immediately afterwards, apply a suitable weedkiller such as triclopyr (SBK Brushwood Killer) or glyphosate (William Sinclair Bramble Killer Ultra or other tough formulations of glyphosate such as Scotts Roundup Ultra 3000, Scotts Tumbleweed, Bayer Tough Rootkill or Doff Maxi Strength Glyphosate Weedkiller) to the freshly-cut ends of the stems, thoroughly wetting them to ground level, following the manufacturer's instructions.
- SBK Brushwood Killer contains a selective or growth-regulating weedkiller (triclopyr) which breaks down in the soil within about six weeks. It controls most broad-leaved weeds and young woody saplings. It does not kill grass, though some damage to lawns and fine turf may occur. It is effective applied to the foliage of woody plants from spring until autumn
- Glyphate-based products such as William Sinclair Bramble Killer Ultra are non-selective, killing both broad-leaved and grassy plants. Glyphosate breaks down in contact with the soil. It is also effective applied to foliage of woody plants from spring until autumn, but SBK Brushwood killer is usually more effective
