Pruning cherry laurel: the twice-yearly cut and tools debate for Tenterden gardens.

Cutting technique · 5 October 2026

Cherry laurel arrived in Britain as a garden ornamental in the seventeenth century and has been commercially propagated as a garden hedging plant since the late Victorian period. Tenterden's main planting wave came in the 1970s to 1990s, when housebuilders developing sites off Ashford Road, East Hill and the streets running south from the High Street toward St Michaels specified cherry laurel for new boundary hedges because it established quickly from pot-grown stock, grew dense in its first two seasons, tolerated shade on north-facing boundaries, and produced a year-round evergreen screen without the maintenance demands of beech or yew. The result is that Prunus laurocerasus now defines the visual character of most of Tenterden's twentieth-century residential streets far more than any other hedging plant. Many of those hedges, planted in the late 1980s and 1990s, are now 35-40 years old, 3-5m tall and a metre wide on each face, having received a hedge-trimmer pass once a year or less throughout their lives.

On Wealden clay, cherry laurel is one of the most forgiving hedging plants you can grow. Its root system tolerates waterlogging in wet winters and drought stress in dry summers far better than beech, hornbeam or yew. In a wet Weald summer, an uncut laurel hedge will extend 60-90cm on all faces from May to September. That vigour is also what makes regular cutting essential: left three years without a cut, a garden cherry laurel hedge that was planted 1m from a boundary fence will have grown into and over the fence, into the road or path, and potentially into a neighbouring property.

The tools question: a decision checklist before you pick anything up

The tools debate around cherry laurel is the one practical question that genuinely divides contractors, and the answer depends on where the hedge is and what it is for. The reason the question exists at all is botanical: Prunus laurocerasus leaves are large, leathery and glossy, typically 10-18cm long and 4-8cm wide. When a hedge trimmer blade cuts across the flat face of a leaf at a random angle, it leaves a dead, brown cut edge on every leaf that happened to be in the blade path. Those brown edges are visible on the outer face of the hedge for 4-6 weeks after cutting, until new shoot growth from the cut buds grows out and covers the damaged leaves. On a hedge cut in May or early June, that 4-6 week recovery period falls in June and July, when the hedge is most visible and the damage most obvious.

Before picking up any tool, run through this checklist:

• Is the hedge on a formal frontage visible from the road or a neighbouring property? Use secateurs throughout, or at minimum for the side faces visible at close range. A hedge-trimmer pass on the rear face, which nobody sees from a distance, is more forgivable.
• Is this an informal rear-garden screen or a farm boundary hedge? A hedge trimmer is acceptable. The loss of appearance for four to six weeks is a reasonable trade for the time saved on a hedge running 30m or more along a field boundary.
• Is the cut in May or June? Hedge-trimmer brown tips will be visible for the whole of early summer. If appearance matters, use secateurs for at least one of the two cuts per year, and make it the spring cut.
• Is the cut in August or September? New growth covers the brown tips faster in the warmer late-summer conditions. A hedge trimmer is more defensible for the August cut than for the May cut on the same hedge.
• Are there sections with stems over 12mm that need removing to bring the profile back? Use loppers on those stems individually. A hedge trimmer blade cannot handle stems above roughly 8mm cleanly and will tear rather than cut, leaving exposed split wood that is an entry point for disease.

The practical approach on most Tenterden garden hedges is to use secateurs as the primary tool, with loppers for any stems that will not close under secateur pressure, and to reserve the hedge trimmer for the final light pass on a large rear or side boundary where secateurs alone would take half a day. If the hedge trimmer is used on the outer face of a formal frontage, follow it immediately with a pass of secateurs to remove the worst of the brown half-leaves by cutting the damaged shoots back to a node. That hybrid approach is slower than trimmer-only but considerably faster than secateurs throughout, and leaves the hedge looking controlled from the moment the cut is made.

The spring cut: late May to early June

Cherry laurel makes its main growth flush in April and May. In a typical Weald spring with adequate rainfall, the new extension on each shoot tip is 30-50cm by the end of May, carrying the fresh, lime-green leaves that characterise the species at its best. By the last week of May these shoots have moved from soft and extensible to beginning to harden at the base of the extension, which is the point at which cutting produces the cleanest wound and the most predictable re-shoot pattern.

Cut too early, in April or early May, and the shoots are still actively extending: the cut stimulates a second flush from the buds immediately below the cut, which arrives within two to three weeks and restores the soft, unruly appearance the cut was meant to correct. Cut too late, in July or early August, and the hedge has been left carrying a full spring flush through the warmest and most visible part of the year; the cut also arrives at a point when the plant is already setting buds for the following spring, which reduces the number of shoots produced below the cut and can leave the outer face looking thin for the remainder of the season.

The summer cut: late August to mid-September

The second flush of growth in a good Weald summer comes in July. By late August it has extended 20-40cm and begun to harden. The August to mid-September cut is the one that determines the hedge's winter profile: done well, it leaves the hedge at its intended finished dimensions, with cut stem nodes that will not produce new extension until the following spring. Missed in a given year, the hedge carries an extra 60-80cm on each face into winter and the following spring's flush starts from a significantly enlarged base, compounding the management problem.

The August cut is also the one where a hedge trimmer is most defensible. New growth covers the cut faces quickly in the residual warmth of late summer, and the brown tips are less visible by mid-September than they would be on the same hedge in June. On farm boundary hedges around the Weald villages, where the hedge is running along a field margin and the primary function is a stockproof windbreak rather than a formal garden boundary, the August trimmer pass is standard practice and entirely acceptable.

Step-by-step cutting sequence

1. Inspect the full hedge before starting. Walk the length of the hedge at close range, checking the interior of both faces for nests. In May and June this is a legal obligation under the Wildlife and Countryside Act 1981 s.1, not a courtesy: an active nest with eggs or young means that section must wait. In August and September, most broods are fledged and the inspection is precautionary, but late broods of blackbird and robin do occur in warm Septembers on Tenterden's sheltered ridge-ground gardens.
2. Assess the profile before cutting. Stand at one end of the hedge and sight along the full length. A cherry laurel hedge growing on rich clay can extend very unevenly between cuts, with south-facing or open sections extending more aggressively than shaded or north-facing sections. Identify the high spots before starting so you know where to take more off and where the face is already close to the intended profile.
3. Cut the sides, starting from the base and working upward. This sequence keeps the lower sections, which are already cut to profile, clear of falling clippings and lets you read the line continuously as the cut progresses upward. On a garden hedge at 1.8-2m height, the typical removal per face is 25-45cm of extension. Take heavy sections in two passes: a first pass to remove the outer half of the extension, then a second pass with secateurs to bring the face back to the intended line.
4. Set a line guide for the top cut on runs over 8 metres. The top face of a cherry laurel hedge is difficult to level by eye on long runs because the large, glossy leaves reflect light differently at different angles, making the surface read as uneven when it is actually level. A taut line between canes at the intended finished height is faster and more accurate than repeated sighting. Take the top cut across the full run before doing any detail work at the ends or at gate openings.
5. Cut the top face, then clear clippings and re-check. Cherry laurel clippings are bulky and accumulate on the top surface during cutting, obscuring the guide line over longer runs. Clear the top surface every 5-6 metres. Once the full run is cut, clear all clippings from the top and stand back to sight the horizontal line from each end. Small tufts and high spots that are invisible from above read clearly against the sky from a low angle at distance.
6. Detail work with secateurs at gate openings and visible corners. The corners where the hedge returns into a gate or wall, and any sections of the formal face visible at close range from a path or road, should be finished with secateurs to tighten the corners and remove cut-face brown tips produced by any trimmer pass. This is the step that distinguishes a contractor who uses cherry laurel's vigour to deliver a clean, precise finish from one who simply cuts to a rough profile and leaves it.
7. Clear all clippings and bag for green waste. Cherry laurel clippings are not suitable for the compost heap in quantity because the leaves break down slowly and produce hydrogen cyanide gas as they decay (the same cyanogenic glycoside chemistry that gives the crushed leaves their bitter-almond smell). Council green waste collection or a licensed green waste composting contractor is the correct disposal route. For farm boundary hedges where sheep or cattle are present, keep clippings well clear of the field: the cyanogenic compounds in fresh laurel clippings are toxic to ruminants, and wilted clippings are more dangerous than fresh ones because wilting increases the concentration of free hydrocyanic acid.

Renovation: what to do with a cherry laurel hedge that has been left for years

Cherry laurel regenerates vigorously from old wood. Hard cuts back to bare brown stem, even stems 50-80mm in diameter, will produce new shoots from dormant buds within four to six weeks in the growing season. This regenerative capacity is one of the species' main practical advantages over Leylandii: a Leylandii cut back to brown wood dies from that point, while a cherry laurel cut back to a 50mm stump will produce a full flush of new shoots from along the length of the remaining stem. This means that renovation work which would be permanent and irreversible on a Leylandii screen is routine and recoverable on a cherry laurel.

For a hedge left two or three years without cutting, broadened but not fully lost, a single-season renovation is possible. In late February or March, before the spring flush, cut all three faces (both sides and the top) back to 20cm inside the intended finished profile. Follow up with the normal twice-yearly trimming in May-June and August-September. The hard-cut stems will have produced sufficient new shoot growth by the first maintenance trim to form a reasonable outer layer, and by the August trim the hedge should be broadly back to a managed profile. The hard cut should be done in late winter to give the cut stems the spring and summer growing season to regenerate before winter: a hard renovation cut in autumn leaves exposed old wood facing winter without the protection of new growth.

For a hedge left five or more years without cutting, broadened to 80cm or more on each face, a two-year phased renovation is safer and more predictable:

1. Late February, year one: cut one side face hard, back to 20cm inside the intended finished profile. Leave the top and the second face at their current dimensions.
2. May-June, year one: inspect the cut face for new shoot development. By this point, cut stems will have produced 20-40cm of new growth. Trim the new shoots lightly to start establishing the finished profile on this face. Carry out the normal maintenance trim on the second face and top.
3. Late August, year one: both faces and the top receive the normal maintenance trim. The hard-cut face will now have a season of growth establishing the new outer layer.
4. Late February, year two: cut the second face hard in the same way. The first face, having had a full growing season of new growth, should be presenting a reasonable green outer layer.
5. Year two onwards: both faces at or near the intended finished profile. Resume the twice-yearly maintenance schedule.

The two-year phased approach on old, established cherry laurel is more cautious than a simultaneous whole-hedge renovation, but it produces better results on hedges that have been carrying structural irregularity in the main stems for years. An old cherry laurel hedge that has been allowed to develop into an unmanaged thicket, 5-6m tall and 2m wide, may have sections where the main stems are hollow or carrying fungal decay from storm damage. Taking the renovation in two phases allows you to assess the condition of the remaining framework after the first phase before committing to the second.

Pricing

A twice-yearly maintenance trim on a typical Tenterden garden cherry laurel hedge of 10-15m at 1.8-2m height, including full clipping clearance and disposal, is priced on the length, height, species and access of the hedge; the general range for routine cuts is on the hedge cutting page. The higher end of any quote reflects hedges requiring secateurs throughout on a formal frontage with restricted vehicle access for clipping disposal. Renovation work on a hedge that has significantly broadened is quoted separately after a site visit, as the volume of removal and the complexity of restoring an even profile vary considerably between hedges of the same nominal length. I quote fixed price on every job, with no charge for a site visit to quote.
