Spring Foraging Walks in British Woodlands

Why Spring Is the Forager's Favourite Season

By mid-March the woodland floor is waking up. The sap is rising, the first leaves are unfurling, and the plants you are looking for are at their tenderest and most flavourful. Spring greens are mild rather than bitter, and they arrive before the canopy closes over and shades everything out.

There is a practical advantage too. The serious hazards of foraging — the deadly fungi — belong to autumn. Spring's target species are largely leafy, aromatic and easy to check with your nose. Best of all, spring foraging pairs naturally with a walk. You do not need a rucksack of kit or a secret location. A footpath through an ancient wood, a hedge-lined lane and two spare hours will do nicely.

The Forager's Code: Picking Responsibly in the UK

The rules vary slightly across the four nations, but the principles are the same wherever you are.

• Pick only what you can identify with absolute certainty. If there is any doubt at all, leave it where it grows.
• Never uproot a plant without the landowner's permission. In England, Wales and Northern Ireland, picking leaves, flowers, fruit and fungi for personal use is generally permitted on land you have lawful access to; digging up a plant is not.
• Take a little from many plants rather than everything from one. A handful from each of several patches leaves the population healthy and the wildlife fed.
• Avoid protected sites. Sites of Special Scientific Interest, National Nature Reserves and many woodland trust properties restrict or forbid picking. Read the notices at the car park.
• Stay off private land without permission, and follow the Countryside Code — close gates, keep dogs under control, take your litter home.
• Never pick from busy roadsides, where exhaust fumes and spray drift are a real concern, or from spots popular with dog walkers.

Wash everything thoroughly when you get home, and cook foraged greens for the first few outings until you are confident in your identification.

Starting with the Unmistakables: Wild Garlic and Three-Cornered Leek

Wild garlic, or ramsons, is the gateway plant, and it is hard to miss. From March it carpets damp woodland floors with broad, soft, lance-shaped leaves, followed by starry white flowers from April into June. The giveaway is the smell: crush a leaf between your fingers and it reeks unmistakably of garlic. If it does not, do not pick it.

The lookalikes are genuinely worth knowing. Lily of the valley and lords-and-ladies grow in the same woods and are toxic. Lily of the valley usually carries its leaves in pairs on a single stem, with a faintly floral scent rather than a pungent one. Always do the crush test, and never rely on sight alone.

Three-cornered leek is another useful allium, common in the south-west and along coastal lanes. It has a triangular stem, white bell flowers striped with green, and the same onion-garlic aroma. Use the leaves and flowers raw in salads or blitzed into butter.

Beyond the Garlic Patch: Nettles, Sorrel and Hedgerow Greens

Nettles are the most generous spring ingredient in Britain. Take the top four leaves of young plants before they flower, wearing gloves, and blanch them for a minute to lose the sting. They make a superb soup, a vivid pesto and a decent cup of tea.

Wood sorrel is the forager's little luxury: three heart-shaped leaflets folded like a shamrock, growing in shade on mossy banks and old tree stumps. It tastes sharply of lemon. A few leaves lifted into a salad are enough — it does not need cooking.

Other plants worth learning this season:

• Garlic mustard (jack-by-the-hedge) — heart-shaped leaves with a garlic-mustard bite, tiny white flowers from April.
• Hawthorn — young leaves in April, nutty and mild, traditionally eaten as "bread and cheese".
• Chickweed — soft, bland and endlessly useful in sandwiches and salads, found at woodland edges and disturbed ground.
• Ground elder — a gardener's curse and a cook's friend; pick the youngest, glossiest leaves for soups and omelettes.
• Beech — the copper-tinged leaves of early May are tender, lemony and lovely in a sandwich.

Staying Safe: Lookalikes, Locations and Kit

Several of the most dangerous plants in Britain grow cheek by jowl with the tastiest ones. Hemlock and hemlock water dropwort resemble wild carrot, cow parsley and flat-leaf parsley closely enough to catch out experienced people. Do not pick any member of the carrot family unless somebody experienced has shown you the differences in the field.

A few habits make the difference between a good day out and a bad one:

• Carry a photographic field guide and cross-check every single plant.
• Use your fingers and nose as well as your eyes — crush, sniff, compare.
• Pick on a dry day, in daylight, so leaves are clean and clearly lit.
• Use a basket or paper bags. Plastic sweats and reduces leaves to mush within an hour.
• Cut cleanly with scissors or a small knife rather than tugging at the plant.
• Tell someone your route and carry an OS map — the best patches are often where the footpath meets a stream.

A Simple Spring Walk to Try This Weekend

Find a stretch of ancient broadleaved woodland — the Chilterns, the Weald, the Wye Valley, or any oak-and-ash wood near you where bluebells are showing. Walk the main path first without picking anything, just to read the ground and get your eye in.

Then follow a hedged lane alongside the wood. Wild garlic usually lines the damp verge, nettles colonise the sunny side, and sorrel hides on the shaded bank. Half an hour of steady picking will fill a basket with more than enough for supper. Wild garlic pesto, nettle soup and a handful of sorrel folded through scrambled eggs is a fine reward for a morning's work.

Go gently, take only what you need, and leave the wood better than you found it. The plants will be back next spring, and so, with any luck, will you.
