Why a living hedge beats a fence

A solid fence or wall looks like the obvious answer to a windy plot, but it often makes things worse. Wind hits an impermeable barrier, is forced up and over, then tumbles down on the sheltered side in damaging eddies. A mixed hedge does something far more useful: it filters the wind, slowing it down and letting a gentle trickle through. Shelter of this kind extends roughly ten to fifteen times the height of the hedge downwind, so even a modest two-metre hedge protects a surprising amount of ground.

That shelter pays you back in several ways. Soil warms sooner in spring. Blossom stays on fruit trees long enough for pollinators to work it. Tall crops such as beans and sprouts stop rocking and snapping. Leaf wetness dries faster, which means less botrytis and less blight pressure. And a mixed hedge is a larder and a nesting site for the birds, bees and predatory insects that keep a garden in balance.

Choosing species for shelter and harvest

The trick is to mix native, tough and useful. A three-species hedge gives you structure in depth, and if one species struggles in your soil the others carry on.

• Hazel (Corylus avellana) — quick, bushy and happy on most soils, including heavy clay. Nuts ripen from late August; beat the squirrels to them. Coppiced stems make superb pea sticks and bean poles.
• Blackthorn (Prunus spinosa) — the toughest of the three, thriving on poor, wet or exposed ground. Snowy blossom in March, dense thorny cover for nesting birds, and sloes from October for gin and cordial.
• Field maple (Acer campestre) — a steady, compact grower with butter-yellow autumn colour and good tolerance of wind and chalk. It knits the hedge together at the base.

If you have room for a fourth or fifth, add hawthorn for a dense thorny frame, guelder rose for berries and autumn colour, or dog rose for hips and a little informal charm. Keep the mix in clumps of three to five of each species rather than alternating one by one, so the hedge looks natural and each plant has neighbours of its own kind.

Buying bare-root whips

Bare-root plants are lifted from the field while dormant and sold with no soil around the roots. They are far cheaper than container-grown stock, establish faster, and can be planted any time from November to early March, provided the ground is not frozen or sodden. Order in autumn for the widest choice.

Look for native provenance stock, which suits British conditions and supports local wildlife. A good whip is 60–90cm tall with a sturdy, straight stem and a healthy fibrous root system showing plenty of fine roots. Reject anything dry, mouldy or with roots that have been crammed into a bag for weeks.

If your plants arrive before you are ready, heel them in. Dig a shallow trench in a spare corner, lay the whips in at an angle, cover the roots with soil and firm it. They will sit happily there for weeks.

Planting day, step by step

Prepare the ground a fortnight ahead if you can, clearing perennial weeds such as couch grass and nettle along a strip at least a metre wide. A hedge competes badly with weeds in its first two seasons.

• Mark out a double staggered row: plants 40cm apart within the row, with 45cm between the rows. This gives a dense, stock-proof base far faster than a single line.
• Dig a hole wide enough to take the roots spread out, but no deeper than the soil mark on the stem. Planting too deep is the commonest mistake.
• Firm the soil in two stages, add a little more, and tread again so the plant cannot be lifted by a gentle tug.
• Cut each whip back by about a third after planting. It feels brutal, but it forces bushy growth from the base instead of one spindly stem.
• Mulch with well-rotted manure or bark, keeping it clear of the stems, and fit spiral guards against rabbits and hares.

Allow at least a metre between the hedge and your nearest bed or row of vegetables. Roots will travel, and the hedge will cast some shade — plan it on the windward side, ideally west or north, never where it will put your plot in shadow.

Aftercare and the first few years

Water thoroughly in the first two summers if the weather turns dry, a full watering can per plant each week. Keep the strip weeded. Beyond that, a mixed native hedge asks very little of you.

Trim lightly in winter for the first two years, just tipping back the strongest shoots to encourage branching. From year three, cut in rotation rather than all at once — trim one side or one section each year so there is always blossom, berries and cover somewhere along the line. Let the hedge reach 1.5–2 metres for real shelter, then hold it there. On an allotment, check your tenancy agreement before planting anything woody on a boundary, and keep it well within your own plot.

Harvesting from the hedge

Sloes are ready from October, once the first frosts have softened them; pick after a cold snap if you can, or freeze them overnight at home. Hazelnuts are ready when the husks turn yellow and the nuts rattle inside — usually late August into September, and you will need to beat the squirrels and jays to them. Field maple gives you nothing for the table, but its wood makes fine kindling and its leaves feed a whole colony of insects.

Harvest lightly and leave plenty behind. The hedge is doing two jobs at once, and the berries you do not pick are next spring's birdsong.
