Leylandii removal in Deal and Walmer: four methods compared, with what to plant next.
Leylandii is the one hedge plant that cannot be renovated from old brown wood. Once it outgrows its space there is no hard-cut solution: it has to come out. This guide compares the four main removal routes for Deal, Walmer and Kingsdown properties, from full DIY to contractor-and-grind, with honest cost ranges for the CT14 area and a species comparison for whatever goes in next.
I get calls about leylandii removal more often than any other single job. Usually it is one of three situations: a hedge that was planted for privacy in the 1990s and is now six metres tall and blocking a neighbour's light, a boundary screen that the previous owner put in on the wrong side of a Deal conservation area, or a windbreak on a Walmer seafront plot that has simply got too wide. In all three cases the answer is the same. The plant cannot be cut back to old wood and recover. It has to come out.
The good news is that leylandii roots, unlike those of privet or laurel, are relatively shallow and not especially invasive. On CT14's fast-draining coastal alluvium and shingle soil, even a large run of leylandii can often be ground out and the ground prepared for replanting within a single working day. What determines the cost and the disruption is access, height and what you want to do with the space afterwards.
| Method | Estimated cost, 10 m run | Who does the work | Stump outcome | Best for |
|---|---|---|---|---|
| DIY felling, stumps left to rot | Skip hire only: £150–400 | You | Stumps rot slowly: 10–20 years | Hedge under 3 m, no replanting planned, access tight |
| DIY felling, hired stump grinder | £60–120/day grinder hire, plus skip | You (felling) + hired machine | Ground cleared to 100–150 mm depth | Confident DIYer, flat ground, clear access for the machine |
| Contractor felling and stump grinding | £300–700 typical CT14 quote | Professional | Stumps ground out, spoil removed or spread | Most Deal and Walmer gardens: clean finish, ready to replant |
| Contractor full clearance with waste and planting prep | £700–1,500+ for tall or wide runs | Professional | Ground levelled, soil conditioned, ready for immediate planting | Tall hedges over 5 m, or where new hedge goes straight in |
Before you start: safety notes for leylandii work
Even a modest leylandii at 3–4 m is a significant felling job. Wear eye protection, ear defenders if using a chainsaw or petrol trimmer, and thick leather gloves. Never work alone when felling: a second person to watch for swing and direct the fall is essential. If the hedge is over 3 m, hire a contractor rather than using a ladder. On Walmer seafront plots and Upper Deal gardens with limited access, a long-reach pole saw is not enough for the main stems: the job needs a chainsaw and a qualified operator. Check for wasp nests before starting any removal work between April and September.
DIY or contractor: what actually determines the decision in Deal.
On paper, DIY felling is cheaper. In practice, three things make it the wrong call more often than people expect on CT14 properties.
First, access. Many Deal and Walmer gardens have a hedge that runs along the boundary of a Victorian or Edwardian terrace, with a narrow side gate as the only route for machinery. A professional stump grinder is typically 900 mm wide in hire form and 1,200–1,500 mm for a commercial machine. If your side gate is under a metre wide, a hire grinder may not get in. A contractor who has worked the CT14 patch knows which machines fit which jobs, and is not hiring by the day at the same rate you would be.
Second, height. Leylandii on a Walmer seafront boundary that has not been cut in five years is often taller than it looks from inside the garden. Once the tops come off there is a surprising volume of material. A 10 m run at 4 m tall generates a skip-load of arisings or more: around 4–6 cubic metres of loose chipped or cut material. DDC's garden waste bin takes none of it at that volume. The Whitfield HWRC at Honeywood Road takes green waste from Dover council-tax payers free of charge, but requires a booking and has a 2 m height barrier on the access road, so a trailer loaded high will not get in. A skip is usually the practical answer, and skip hire in the CT14 area runs from around £180 to £350 depending on size and duration.
Third, the stumps. This is where DIY leylandii removal most often stalls. The stems come down quickly enough. The stumps are another matter. Leylandii roots do not re-sprout, which is the one thing in your favour, but the root plate is wide and fibrous. On CT14 shingle and alluvium soil the lateral roots can run two to three metres from the main stem. Leaving them in place is fine if you are putting in a fence or a new fence post line behind the old hedge, but if you want to replant a new hedge in the same run, the old root mass will compete with new planting for the first two to three years. Grinding the stumps is almost always worth doing when replanting is the plan.
Conservation area check: do this before any work starts.
In Deal, Walmer and Kingsdown, seven conservation areas administered by Dover District Council (DDC) cover much of the town. The section-211 notice requirement under the Town and Country Planning Act 1990 applies to individual trees with a stem diameter over 75 mm at 1.5 m from the ground. Leylandii grown as a hedge, and cut in its hedge role, falls outside the notice requirement in most cases. But a long-established leylandii run where individual stems have grown past 75 mm is a different matter. Each stem is measured separately.
If your property sits inside one of the seven CAs (Middle Street, Upper Walmer, Kingsdown, South Barracks, Nelson Street, Upper Deal or the seafront CA), check the stem diameters before booking any removal work. The full section-211 guidance is in my conservation areas and hedge rules guide. I check this as part of my quoting process for every CT14 removal job at no charge.
Nesting season: the timing constraint you cannot ignore.
Wildlife and Countryside Act 1981, section 1
It is an offence to intentionally take, damage or destroy an active wild bird's nest. Nesting season in the UK runs from 1 March to 31 August. Fines run to £5,000 per nest, with up to six months in prison. The safe removal window is September to the end of February. For any leylandii removal job planned during the March-to-August window, a survey walk of the hedge line is required before the first cut. Leylandii runs in CT14, particularly along Kingsdown lanes and Sholden field boundaries, hold sparrowhawk, dunnock, blackbird and collared dove nests regularly in season. Do not assume a dense dark hedge is empty because it looks impenetrable from outside.
Video reference: leylandii removal in a UK garden.
Anthony at TRC Garden, a UK-based gardening channel, produced a practical walkthrough of removing a leylandi hedge including felling technique, root management and ground preparation. The video is hosted on the TRC Garden YouTube channel and is a useful companion to this guide for the physical felling steps. I have not embedded it here as his channel covers a range of garden situations: search "Removing a Leylandi Hedge TRC Garden" to find it. Anthony works from a northeast England garden, so his soil conditions differ from CT14 coastal alluvium, but the felling sequence and stump approach translate directly.
What to plant in place of leylandii.
The ground after a leylandii run is not as depleted as people expect. Leylandii does not produce the allelopathic soil inhibitors that some conifers do. The main issue is the old root mass: fine fibrous root material will take two to three growing seasons to break down in CT14's free-draining soil. For immediate replanting, grinding the stumps and tilling through the top 300 mm with a soil conditioner (garden compost or processed green compost from the Whitfield tip) gives new planting the best start.
| Species | Salt tolerance on CT14 coast | Years to a closed hedge at 1.5 m | Bare-root cost per metre run | Notes for Deal and Walmer |
|---|---|---|---|---|
| Privet (Ligustrum ovalifolium) | Good | 2–3 | £3–5 | Fast establishment in post-leylandii ground, tolerates competition from remaining roots. Three cuts a year needed once established. |
| Portuguese laurel (Prunus lusitanica) | Very good | 3–4 | £8–15 | Slower but very reliable on CT14 alluvium. Handles a Walmer seafront site better than cherry laurel. |
| Griselinia (Griselinia littoralis) | Excellent | 3–4 | £8–15 | The obvious choice for a seafront replacement. Pot-grown rather than bare-root for year-round planting. |
| Thuja plicata 'Brabant' | Moderate | 3–5 | £5–10 | The sensible conifer replacement: handles CT14 coastal alluvium, can be cut back hard into green wood unlike leylandii. Not for the most exposed seafront positions. |
| Mixed native (hawthorn-led) | Good | 4–5 | £1–3 | Cheapest option, best wildlife value. Suits Sholden lanes, Kingsdown approach roads and the rural edges of Mill Hill where a formal hedge is not needed. |
Leylandii's main appeal was screening speed. The replacements above are slower to close, but all of them can be cut back hard if they outgrow their space. That is the trade leylandii could never offer. On a Walmer seafront plot where you are replacing a 5 m leylandii run with griselinia, expect three to four years before the new hedge is at 1.5 m. A semi-mature griselinia at 1.2–1.5 m, planted directly from a 10-litre pot, will close the visual gap faster: costlier at £20–40 per plant, but the right answer when privacy matters in year one.
The stump grinding question in more detail.
A hire stump grinder from a CT14-area plant hire firm typically costs £60–120 for a day, plus delivery. The standard hire machine is a walk-behind unit that grinds to around 150 mm below ground level. That is enough for a fence post line or a lawn, but not quite enough for replanting a new hedge in the same run: new roots from hedge plants at 1.5–2 m spacing need at least 300 mm of unobstructed soil to establish. For a post-leylandii replant, I normally advise either grinding to full depth with a commercial machine (which a contractor will bring, and which costs more) or offsetting the new planting line by 300–400 mm from the centre of the old stumps. On a narrow Deal garden boundary that second option is often not practical.
A professional contractor with a commercial grinder will typically grind to 250–300 mm. The grinding spoil (a mix of wood chips and soil) can be left in situ as an organic mulch layer, taken away in a skip, or spread across a border. It is not suitable as a topsoil layer for immediate turf: the carbon-rich wood chips will lock up nitrogen for one to two years as they decompose. Either spread it thin as a mulch, or take it away and top-dress with compost before seeding.
How I approach a leylandii removal quote in Deal.
When I quote a leylandii removal in Deal, Walmer or Kingsdown, I look at five things before I give a number.
- Height and stem diameter. Height determines how the tree comes down (top sections first for tall specimens, flush cut for shorter ones). Stem diameter at the base determines grinder size and time on the stump.
- Access for machinery. Gate width, road parking restrictions (relevant on Middle Street and the seafront terraces), and the clearance between the hedge and the house or fence.
- Conservation area. I check the DDC mapping layer. If any stems are over 75 mm at chest height and the property is inside a CA, a section-211 notice is required before the work starts. I file it.
- Waste route. Whether the arisings go by skip (my preference for volume), chip-in-situ, or DDC garden-waste bin for smaller jobs. For a 10 m run of mature leylandii, a skip is almost always needed.
- What goes in next. If the client wants a new hedge, I allow for stump grinding to full depth and soil preparation in the quote. If it is a fence or a lawn, I allow for grinding to 150–200 mm and spreading the spoil.
For most Deal and Walmer leylandii removal jobs I see, a contractor quote in the £400–700 range for a 10–12 m run including grinding and waste removal is a reasonable expectation. Tall runs over 5 m, or jobs with poor access, go higher.
