Why Lay a Hedge at All?

A well-laid hedge is one of the great quiet achievements of rural Britain. It is a boundary, a windbreak, a stockproof fence and a wildlife corridor all in one, and it will outlast most things you could build out of timber or wire. Left alone, a hawthorn hedge will eventually grow into a line of spindly trees with a bare, gappy base. Lay it properly and you reset the clock: the stems are cut and bent over while still attached to the roots, so they carry on growing, thicken up, and send fresh shoots from the base.

The first laying you do on an overgrown boundary will feel like hard labour. The second will feel like craft. By the third, you will start to see the hedge as a living thing with opinions.

Timing, Species and a Word on the Law

Traditional laying runs from roughly the end of October through to the end of February, while the sap is down and the hedge is dormant. That window matters for a practical reason as much as a biological one: cut wood is far more pliable in winter, and you will snap fewer stems. In England and Wales, the nesting season effectively closes the season on 1 March, so plan your work to finish before then. Never lay during a hard frost — frozen stems shatter instead of bending.

Take a walk along the hedge before you start and note what is in it:

• Hawthorn and blackthorn — the classic spine of most British hedges, wonderfully tough and forgiving.
• Field maple, hazel and ash — useful for taller, stiffer stems and often good for binders.
• Elm and elder — brittle, best left standing or removed; they rarely pleach cleanly.
• Oak, ash and mature crab apple — leave these as standards at intervals to grow up above the laid hedge.

Clear the base of brambles, nettles and dead growth first with a brushcutter or a sharp slasher. Good light at ground level is the whole point of the exercise, and you cannot cut what you cannot reach.

The Basic Cuts

The technique that defines hedgelaying is called pleaching. You cut part-way through each stem near ground level and bend it over horizontally, letting it continue to grow from a sliver of connecting wood known as the hinge.

For a stem of, say, 50mm to 100mm across, work with a sharp billhook or a small axe rather than a chainsaw — you need control, not speed. Make a sloping upward cut on the side you are laying towards, ideally at a shallow angle of around 30 degrees, and aim to leave roughly a quarter to a third of the stem intact as the hinge. Too thick and it will snap; too thin and the stem dies. On the opposite side, make a small nick to relieve the pressure where the stem beds down against the ground, but never cut all the way through.

Bend the stem gently over towards you. If it resists, don't force it — deepen the cut slightly or start again. A stem that cracks audibly has told you the truth: it will not survive, so trim it short and let the base regrow.

Lay the pleachers at 30 to 40 degrees from horizontal, leaning consistently in one direction along the hedge line, with each stem overlapping the one before it. Position the cuts so the stubs sit neatly on the ground, or on the bank in the Devon and Cornish styles.

Styles Worth Knowing

Regional styles evolved around soils, livestock and local timber, and each has its own logic.

• Midland Bullock — the most widespread. A single-row hedge laid at a shallow angle with a brashy face on both sides; the stems are trimmed so the hedge tapers to a broad base.
• Devon and Cornish — laid into an earth bank, with the hedgers digging turf and soil to hold the stems.
• Welsh Border — intended to be stockproof, with a dense, tight top and heavy binding.
• Lancashire and Westmorland — a narrower, sharper-cut style with crooks and straight stakes.

Choose the style that suits your site, your livestock and the stems you actually have. There is no prize for purity; a tidy hedge that works is worth more than a fashionable one.

Stakes, Binders and the Finishing Ties

Once the stems are down, you need to hold them there. Drive stakes at roughly 45cm to 60cm intervals, following the line of the hedge and angling them slightly away from the face. Use hazel, ash or sweet chestnut, about 40mm to 60mm thick, and set them deep enough to be genuinely firm — aim for at least 30cm into the ground.

Binders are the woven rods that run along the top, holding down the pleachers. Cut them about a month in advance and soak them, or cut them fresh from hazel, willow or sweet chestnut while they are still green. Twist two or three rods together, wind them tightly around the tops of the stakes, and draw each one through with a twister or lever stick. Done properly, the knots hold without any need for string or nails, and will still be there in ten years.

Trim the finished job with a billhook, cutting straggling top growth back to a clean, unfussy line. Leave the brash in a low pile nearby rather than burning it: it is cover for small mammals and foraging ground for birds.

Aftercare and Wildlife

A laid hedge is not finished — it is started. Keep livestock out for the first two growing seasons, or the new growth will be grazed off before it can establish. Inspect after spring growth and again the following autumn, trimming the sides lightly to encourage a dense face while keeping a bushy top. A hedge should be wider at the base than the top, like an A; that shape sheds light and stops the base going bare.

Lay no more than a third of a long hedge in any one year, and rotate over a decade or so. Leave one or two standards every 20 metres or so, leave the occasional gappy section untouched, and keep a few dead stems standing. Yellowhammers, whitethroats, bullfinches and song thrushes all benefit from that patchwork of ages, and dormice in the western counties rely on those taller, older stretches. A well-managed hedge boundary will reward you with nesting birds, autumn hips and sloes, wildflowers in the ditch, and the particular satisfaction of a fence you grew yourself.
