A hedgerow is the single most generous thing you can plant in a British garden, smallholding or field boundary. Within a few years it will be a larder, a windbreak, a nesting site and a corridor all at once. Get the mix of species right and it will also give you material for the workshop — bean poles, pea sticks, spars and hurdles — for decades to come.

Why a Mixed Hedge Beats a Single-Species Fence

A row of one species tends to flower and fruit all at the same time, then offer nothing for the rest of the year. A mixed hedge staggers its offering: blossom in spring, berries and nuts from late summer through to February, and leaf litter underneath for beetles and hedgehogs. It also insulates you against disease. If one species suffers a bad year, the others carry the load.

Density matters as much as diversity. Birds such as dunnock, wren and robin need a hedge that is thick at the base and slightly domed on top — a shape that sheds rain, keeps the centre dry, and puts a thorny wall between a nest and a passing cat or magpie. A thin, leggy hedge offers shelter for nothing.

The Four Workhorses

Hawthorn, blackthorn, hazel and field maple cover nearly every job a boundary hedge needs doing.

• Hawthorn (Crataegus monogyna) — the backbone. Quick to establish, fiercely thorny, and its May blossom feeds early bees and hoverflies. Autumn haws keep redwings and fieldfares going well into winter.
• Blackthorn (Prunus spinosa) — flowers on bare wood in March, the earliest nectar of the year, followed by sloes for gin and for the thrushes. It suckers freely, so give it room or plant it at the end where spreading is welcome.
• Hazel (Corylus avellana) — the craftsman's species. Catkins in February, nuts in September for dormice, jays and squirrels, and straight coppice rods every seven to ten years. Hazel tolerates shade better than the others.
• Field maple (Acer campestre) — the quiet one. Golden autumn colour, good for moths and aphids, and it grows well on heavy clay where hawthorn sulks.

If you have space, slip in a few guelder rose, dog rose, spindle or crab apple for extra flowers and winter colour. Keep these to roughly one in ten plants so the structure stays thorny.

Ground Preparation and Spacing

Order bare-root whips, 60–90cm tall, for planting between November and March whenever the ground is not frozen or waterlogged. Bare roots are cheaper, establish faster and come without plastic.

Clear a strip at least a metre wide on each side. Grass and nettles will out-compete young whips ruthlessly in the first two summers, so this is the step people skip and later regret. Fork over the strip, remove perennial weed roots, and add well-rotted manure if the soil is poor.

Plant in a double, staggered row at 30–40cm spacing — roughly five to seven plants per metre. Offset the two rows so the hedge fills in from the middle outwards. On a windy, exposed site dig a shallow trench rather than individual holes; it is quicker and keeps the roots moist while you work.

Planting and the First Three Years

Firm the soil around each whip with your heel, then cut the top growth back by about half. It feels brutal, but it forces the plant to throw side shoots from the base and gives you a bushy hedge rather than a row of beanpoles.

• Fit spiral guards against rabbits and voles; stake only if the site is very exposed.
• Mulch with bark chip or straw to suppress weeds, keeping it clear of the stems.
• Water well through the first two summers if rainfall is short. One good soak beats five light sprinkles.
• Trim the sides lightly each winter, aiming for a slight batter — wider at the base than the top.
• Leave the top alone for the first three years and let it gain height.

Never cut between March and the end of August. Nesting birds, and in some cases the law, depend on it.

Laying, Coppicing and the Craft Tradition

Once the hedge reaches two metres or so, it can be laid. Part-cut the stems near the base and bend them over at an angle, weaving them between upright stakes and binding the top with hazel or willow. Laid hedges live far longer than flailed ones, thicken at ground level, and produce the dense, weatherproof barrier that traditional boundaries were built on. Regional styles differ — the Midland bullock hedge, the Devon bank with its earth and stone base, the Welsh stake-and-binder.

Hazel is your raw material. Coppice a stool on a seven-year rotation and you get rods for hurdle hurdles, thatching spars, tool handles and garden obelisks. Straight lengths become bean poles and pea sticks; brash goes to the woodpile or a dead hedge for wrens. Hawthorn trimmings make excellent Kindling and, laid in a pile, a home for stag beetles.

Making the Hedge Work All Year

Cut on rotation rather than all at once. Trim one third of the length each winter so there is always older, berry-bearing wood standing while the rest regenerates. Leave the occasional standard — a hawthorn or field maple grown up on a clear stem — for blossom, song posts and shade. Let a patch of nettles and cow parsley run at the base; they feed the caterpillars and hoverflies that in turn feed the chicks in the hedge above.

Plant it well, protect it for two summers, and a mixed hedgerow will repay you with birdsong, sloes, hazel rods and a boundary that keeps its own weather. It is one of the best long-term investments a British garden or smallholding can make.
