A Seasonal Guide to Foraging in British Hedgerows

Reading the Hedgerow Year

A hedgerow is not simply a fence made of leaves. It is a woodland edge in miniature — a narrow, layered strip of hawthorn, blackthorn, hazel, field maple, dog rose, honeysuckle and bramble that has been cut and laid by human hands for centuries. That management is exactly what makes it so generous. Because the hedge is continually trimmed, new growth is soft and reachable, and the fruiting bodies that follow are within arm's reach of anyone walking a footpath.

The trick to good foraging is not enthusiasm but timing. Each hedgerow plant offers its harvest in a narrow window, and picking at the wrong moment means small, sour fruit and unnecessary damage to the bush. Below is a guide to the three great hedgerow harvests of the British year, along with the habits that keep the hedge healthy for everything else that depends on it.

Late Spring: Elderflower, May to Mid-June

Elder is unmistakable once you know it: a shrubby tree with corky, fissured bark, pinnate leaves, and flat-topped frothy heads of tiny cream flowers that smell of muscat and honey. It grows in hedgerows, along lanes and on waste ground, often where the soil is rich in nitrogen.

Pick on a dry, sunny morning when the flower heads are fully open and the pollen is dry. Snap the stalk just below the head rather than pulling at the branches, and never strip a bush bare — leave at least half the heads standing, because those flowers become the elderberries that blackbirds, song thrushes and fieldfares will rely on in October.

• Take only from waist height or above on roadside bushes, away from exhaust fumes and spray drift.
• Never confuse elder with other white umbellifers. Cow parsley and hogweed are harmless, but hemlock water dropwort is not. Elderflower grows on woody, shrubby stems and has a distinctive rank-sweet scent; its flower heads are flat rather than domed.
• Use them quickly. Twenty heads steeped in 1.5 litres of water with 1.5kg of sugar and the juice of two lemons, strained after a day, makes the classic cordial.

High Summer to Early Autumn: Blackberries, August to October

The bramble is the forager's most reliable ally, and the hedgerow's best nesting cover. Wrens, whitethroats and long-tailed tits raise broods deep inside the thorny tangle, so tread carefully and never hack back stems to reach fruit.

Pick only berries that come away with the gentlest pull and are fully black to the tip — a blackberry with red shoulders is sour and will never ripen once picked. Work along the middle of the bush first, leaving the topmost clusters for the birds, which need them far more than we do. A shallow tub or wide basket prevents crushing; freeze the berries on a tray before bagging so they don't clump.

Fruit that has been sprayed, or that hangs low enough for dogs to reach, is best left alone. Pick from knee height upwards, rinse in cold water, and use within a day or two for jam, crumble or vinegar.

Autumn: Hazelnuts, September to October

Wild hazel grows throughout British hedges, recognisable by its round, serrated leaves and dangling catkins in spring. By September the nuts sit in clusters of two or three inside a green, ragged husk. They are ready when the husk turns yellow-brown and the nut rattles faintly inside.

Gather from the bush rather than the ground where you can, since fallen nuts may be old or damp. Squirrels, jays, mice and the protected dormouse all depend on this crop to lay down winter fat, so take a modest share from any one bush and move on. At home, spread the nuts in a single layer in an airy tray for two or three weeks, then store them in their shells in a cool, dry place.

The Forager's Code

A few plain rules keep this pastime legal, sustainable and welcome.

• Ask permission before picking on private land, including farmland and the verges beside it.
• Pick for personal use only. Under the Wildlife and Countryside Act 1981, the flowers, fruit and foliage of common plants may be gathered by hand for personal consumption, but uprooting any wild plant is an offence.
• Leave two-thirds behind on every bush — for birds, insects and next year's crop.
• Take one species at a time and avoid trampling the hedge bottom, where small mammals and invertebrates live.
• Stay out of nature reserves and Sites of Special Scientific Interest unless you have written permission.

Winter Work and the Year Ahead

By November the hedgerow's job changes. Hawthorn and holly berries feed redwings and fieldfares arriving from Scandinavia, while blackthorn sloes hang on for gin-makers and hungry thrushes. This is not a season for harvesting but for repair.

Traditional hedgelaying runs from late autumn to early March, before nesting begins. A hedge that is cut and laid — partially severed near the base and bent over at an angle — regrows thicker and denser, providing better shelter and more flowers the following spring. If you have a hedge of your own, planting bare-root whips of hazel, hawthorn and dog rose between November and March will build the next generation of foraging ground.

Keep a small notebook of what you find and when, year on year. The hedgerow keeps its own calendar, and after a few seasons you will begin to read it as clearly as the sky.
