Hawthorn boundary hedge: lay it or keep flailing it?

A hawthorn field boundary that has been flailed every year for two decades does not look obviously wrong, but it is often slowly failing. The base thins, gaps open at ground level, and what was a stockproof barrier quietly becomes a line of bushes propped up by the fence behind it. The real question for a Goodnestone or Chillenden farmland hedge is not whether to cut it, but whether it has reached the point where mechanical cutting can no longer fix what's wrong with it, and hedgelaying is the only honest answer.

The decision: have it laid or carry on flailing

Pros of hedgelaying

• It addresses the base, which annual flailing cannot. Partially cutting the main stems (the "pleachers") and laying them at a low angle along the hedge line forces vigorous basal shoots that close the gaps mechanical cutting leaves open indefinitely.
• A properly laid hawthorn hedge is genuinely stockproof again within two growing seasons, which matters on the field boundaries around Chillenden and Knowlton where livestock still graze.
• Wildlife value is substantially higher. Research by Habitat Aid and published conservation studies consistently find that laid hedges support greater invertebrate diversity and more bird species than flailed hedges of the same species, for the same length of time after the work.
• The structural fix is long-lasting: a well-laid hedge in good hawthorn or blackthorn should hold its structure for 20-30 years before it needs laying again, at which point it can be repeated.
• Countryside Stewardship capital grants (item HO6 for hedgelaying) are available on farms in Higher Tier agreements in the Dover District area, which can recover a meaningful share of the cost. It is worth checking your agreement before assuming you are paying in full.

Cons of hedgelaying

• The cost is real. Contract hedgelaying costs considerably more per metre than mechanical cutting, depending on stem density and condition, and any clearing work needed before the layer can start adds to it; get quotes from local hedgelayers.
• The hedge looks severe for one full growing season before it re-feathers. If it sits on a road frontage or a garden boundary the owners care about aesthetically, that year matters.
• Finding a skilled layer locally takes planning. The National Hedgelaying Society directory covers the South East, but there are only a handful of experienced layers working the Wingham area and they book up through the winter season, November to March, early.
• Hedgelaying only works on a hedge that still has live, pliable stems to lay. A hedge that has been flailed to dead stumps with nothing viable left upright is past laying: it needs gap-filling and replanting, which is a different and more expensive operation.

Pros of continuing annual mechanical cutting

• The cost is low: annual flailing or mechanical trimming by a contractor is the cheapest way to keep a hedge to a set height and width, and is perfectly adequate for a hedge that is still structurally sound.
• It keeps a predictable shape, which is the right priority for ornamental boundary hedges on village properties or road-facing frontages where appearance matters more than stock-proofing.
• Any competent contractor can do it with standard equipment, with no specialist skills or booking lead time required.
• There is no point laying a hedge that does not need it. If the base is dense and the hedge is doing its job, annual cutting is the correct, lower-cost option.

Cons of continuing annual mechanical cutting

• It cannot close gaps. A hedge with openings at the base, caused by years of top-only flailing and the natural dieback of shaded lower stems, will not recover that structure from continued cutting alone. The gaps simply persist.
• The hedge gradually gets thinner at the base over successive years of flailing with nothing to stimulate downward growth, a slow decline that is invisible season-to-season but obvious at 20 years.
• A hedge that is already compensating with straining posts and wire has already crossed the threshold where mechanical cutting was no longer sufficient. The wire is the symptom.

How to actually decide

Stand back and look at the base of the hedge in winter, when the leaves are off. If the lowest 30-40 centimetres are still dense and twiggy with live growth down to ground level, the hedge is structurally sound and flailing is the right maintenance regime. If the base is open, with clear gaps you could step through, or if you are relying on fence wire to keep animals in, laying is overdue. Applying more frequent flailing to a gapping hedge is not a fix: it will not stimulate the basal regrowth that only laying, or severe coppicing, can produce.

The Countryside Stewardship question is worth checking specifically on the Chillenden and Rowling estate boundaries, where some parcels already sit in agri-environment agreements. If a Stewardship grant covers even part of the laying cost, the economics of the decision change considerably.

What hedgelaying actually involves

The layer works in the dormant season, November through February. Each main stem is partially cut through at the base (but not severed completely) and then bent along the line of the hedge at a low angle, held in place by woven upright stakes. The partially cut stems, still drawing sap from the root system, produce vigorous side shoots the following spring. A trained layer covers 15-25 metres per day, depending on the density and condition of the hedge.

In Kent and the rest of the South East the standard style is the Midland style, with single-sided stakes and a brushwood finish along the top. On farm field boundaries where stockproofing is the goal this is the practical choice. The result looks more open than a maintained hedge for the first year, then quickly closes in as the basal and lateral shoots come away.

Finding a hedgelayer in the Wingham area

The National Hedgelaying Society maintains a regional directory of qualified layers at hedgelaying.org.uk. When contacting anyone for a quote, ask which style they work in (Midland is the standard for this area), whether they clear and remove the arisings as part of the day rate, and what condition they expect the hedge to be in before they start. Some layers will not take on a hedge that has not been cleared of the barbed wire, old posts and bramble growth that accumulates along neglected boundaries, and that pre-clearing work is a separate cost.
