Short answer
Most broadleaf hedges (beech, hornbeam, privet, laurel, hawthorn) can be hard pruned in late winter and will regrow. Most conifers cannot, except yew. For a big reduction, spread the work over two years, and always check for nests first.
The RHS says most hedges can be cut back substantially and regrow from old wood, but most conifers will not; it advises replacing an overgrown conifer hedge rather than renovating it.
Plan the work
| Stage | What to do |
|---|---|
| Year 1, late winter | Cut one side back hard, and reduce the top height if needed |
| Year 1, summer | Trim new growth lightly |
| Year 2, late winter | Cut the other side hard |
| Year 2 onwards | Maintain with regular trims |
Tools
Thick stems may be beyond a standard hedge trimmer. Use loppers or a pruning saw for stems above the trimmer’s capacity, or choose a trimmer designed for thicker branches. See trimmers for thick branches and cutting capacity explained.
Safety
- Wear eye protection, gloves and sturdy footwear.
- Use stable steps or a platform, not a leaning ladder.
- Clear a safe area for falling branches.
