Sometimes, and the answer is decided by one thing you can check yourself in two minutes. This is the article to read before ringing anybody, because it will tell you whether the quotes you are about to collect are for something achievable.
The rule
Yew is the one exception — it is a conifer that does reshoot from old wood, which is why it has been used for formal hedging for centuries and why an overgrown yew hedge can be cut back almost to the frame and recover.
The check
Push a hand into the hedge and find how far in the green goes before it turns brown. Do it in three places: the top, and each face separately. They will give different answers.
| Green depth | What is realistic |
|---|---|
| 12in or more | Substantial reduction available |
| 6–12in | A useful reduction, especially on top |
| 3–6in | A modest trim rather than a reduction |
| Under 3in | Reduction not really available |
The top almost always holds more green than the sides, because it gets more light. So on a neglected hedge you can often take real height off even when the faces have almost nothing to work with.
How it got this way
Worth understanding, because it explains why the clock matters. A conifer hedge only produces foliage where light reaches. Each year it is not cut, the outer shell grows further out and shades the growth behind it, which dies back and turns brown.
So the green shell stays roughly the same thickness while moving steadily outward, and the bare brown interior grows behind it. The distance you can ever cut back to shrinks every single year.
That is the real argument for keeping a conifer hedge on an annual cut. Not tidiness — preserving the option to make it smaller later.
If there is enough green
Then the work is straightforward, and the main practical consideration is the waste. Conifer arisings are dense, heavy and bulky, and a long hedge reduced by a few feet produces far more material than people expect. Chipping on site is usually the sensible answer and worth agreeing before the work starts.
Take a little more than feels necessary. The hedge grows between cuts, and coming back below your target buys a season.
If there is not
Then the honest options narrow, and it is better to hear that plainly than to pay for a cut that leaves the hedge brown.
- Live with it, cut annually within the green. The hedge stays roughly this size but stops getting worse.
- Take the height only. Often achievable even when the faces are not, because the top holds more green.
- Accept a brown face temporarily. Some people do this on a boundary they do not look at, planting something in front of it.
- Remove and replace. The clean answer where the hedge is too big for the garden and cannot be reduced.
If you replace it
| Replacement | Screening restored | Long-term |
|---|---|---|
| Beech or hornbeam | 5–8 years | Far more forgiving — recovers from hard cutting |
| Yew | 8–15 years | The best formal hedge; cuts back hard |
| Laurel | 3–5 years | Fast and forgiving |
| Another conifer | 3–5 years | Same problem again in twenty years |
| Fence | Immediate | Limited to about 2m without permission |
The fence height point is worth checking before deciding. Under permitted development a boundary fence is generally limited to two metres, so it will not replace the screening a four-metre hedge was providing.
A note on the neighbour's side
If the hedge is a neighbour's and you are cutting your side back to the boundary, be careful. Cutting a conifer flush to the line very often means cutting into brown wood, and the permanently bare face is then on your side. It is legal and it is frequently a mistake.
