Hedge trimming is one of those tasks that looks simple but has important nuances — trim at the wrong time of year, cut too hard or use the wrong technique and you can damage a hedge significantly. Here is the professional approach for the most common hedge species in Hampshire gardens.
Timing by Hedge Type
The timing of trimming matters enormously, both for the health of the hedge and for legal reasons — nesting birds are protected by law and hedges should not be cut between March and August without first checking for active nests.
- Beech and hornbeam: once in late summer (August)
- Box: twice — late May and September
- Yew: once in late summer, lightly in spring if needed
- Privet: two or three times through the growing season
- Laurel: cut with secateurs, not shears, to avoid browning
- Native mixed hedging: ideally once in late winter
Technique for a Good Finish
Always cut the top of a hedge slightly narrower than the base — this "battered" profile allows light to reach the lower growth and prevents the hedge becoming bare at the bottom over time. Use sharp, clean blades and work from bottom to top.
After Trimming
Feed hedges with a general-purpose fertiliser after trimming to support recovery and new growth. Water in dry spells for the first few weeks after cutting. Clear all clippings to prevent disease.
