The first thing to understand about foraging in British woodlands is that nothing happens on a date. A warm spring on a south-facing slope in Devon can push elderflowers out a fortnight before a cold wood in the Pennines has even finished leafing. Frost, altitude and aspect all shift the calendar. What barely changes is the order of things. Learn the sequence — ramsons, elderflower, bilberries, green hazelnuts, brambles, sloes, chestnuts, then the hips and haws of winter — and you will arrive at the right places at roughly the right time, rather than reading about a crop a month after it has gone.
Spring: the lean months, and the best time to learn
March to May is less a harvest than homework. There is food, but it is mostly leaf and flower: wild garlic in damp ash and alder woodland, three-cornered leek along shaded lanes, young nettles, wood sorrel in the moss under oaks. Elderflower arrives at the end of May in the south, and often not until mid-June further north.
Use the quiet weeks to read the wood. Hazel is easy to spot in April, its leaves soft and round-tipped. Sweet chestnut shows long, glossy, serrated leaves. Blackthorn — the sloe tree — is the one that flowered white on bare black twigs back in March, before the leaves came. Mark where these trees are now and September becomes a great deal easier.
Early summer: small fruit, big flavour
June and July bring the first things worth carrying a container for. Wild strawberries grow on sunny rides and old banks, the size of a fingernail and worth every minute of the picking. On acid soils — the oak and birch woods of the Pennines, the Welsh hills, the Highlands, the New Forest — bilberries ripen in July. They go by a dozen local names: whinberry, blaeberry, wimberry, hurtleberry. The bushes are low and the berries are small, and your back will ache; take a friend, because the picking is faster with conversation.
Wild raspberries arrive at about the same time, in clearings and along the fence lines where the wood meets open ground. Elderflowers are over by early July, so cordial is a late May and June job.
Late summer: green hazelnuts
Hazelnuts become worth having in the second half of August. A green nut — pale shell, husk still soft and lime-coloured — is milky and sweet, and nothing like the dry kernel you buy in December. It will not keep, so eat it on the walk.
For storing, wait until the husk yellows and begins to open and the nut rattles inside when you shake it. That is late August into September, and it is also when the squirrels declare open season. You can judge a crop by the woodland floor: gnawed shells on stumps and roots mean there is something worth hunting for. Expect to share. A hazel stool gives up a handful, not a sackful, and that is how it should be.
Autumn: the main harvest
September and October are why most people start foraging. Brambles first: the best blackberries come early, before rain swells and sours them and grey mould sets in. Then the hedges empty themselves in a rush — rowan berries, haws, rosehips, crab apples, bullace, damsons.
Sloes
Sloes ripen from September. Raw, they are aggressively astringent, and eating one and concluding the crop is useless is the classic mistake. The old advice is to wait for the first frost. Frost softens the skin, but a night in the freezer does the same job. Either way, they are for gin, jelly and liqueur rather than eating out of hand, so prick or freeze them first to split the skins.
Sweet chestnuts
Sweet chestnuts fall from October, sometimes into November. The husks are dense and covered in fine spines like a sea urchin — wear gloves, or learn to roll them open underfoot. The nut should be brown and firm, with a pale, slightly pointed base. A glossy round nut with a flat white scar is a conker, which is not edible: horse chestnut husks are lumpy and sparse rather than densely spiny, and horse chestnut leaves are palmate, five or seven leaflets from one stalk, against the long, toothed, deeply veined leaves of sweet chestnut.
Gather after a windy night, when the husks have split and dropped. Cut a small cross in the flat side before roasting, and discard any nut that feels light or rattles in the shell.
Winter: hips, haws and what the squirrels missed
By November the wood is mostly done, but not empty. Rosehips hang on into the new year and soften after a frost. Haws and the last rowans make good jelly, with crab apples added for pectin. Late sloes are still on the blackthorn if the birds have not finished them, and under the leaf litter beneath a good hazel you can find the odd nut the squirrels overlooked.
Winter is also the best scouting season. With the leaves down you can see the shape of a wood: which oaks are heavy with acorns, where beech mast lies thick, which hazel stools were cut recently. The foragers who do well in September are the ones who marked their trees in February.
The year at a glance
- March–April: wild garlic, nettles, wood sorrel. Scout hazel, blackthorn and chestnut.
- May–June: elderflower from late May onwards.
- June–July: wild strawberries, wild raspberries.
- July–August: bilberries on acid soils; green hazelnuts from mid-August.
- August–September: blackberries, ripe hazelnuts, rowan, haws, rosehips.
- September–October: sloes, crab apples, bullace, damsons.
- October–November: sweet chestnuts, beech mast, walnuts.
- November–February: rosehips, late haws, overlooked nuts, and the best scouting conditions of the year.
Before you go: kit, habits and ground rules
Take less than you want. A basket or canvas bag lets soft fruit breathe; plastic bags sweat and turn blackberries to pulp. Gloves save your hands on brambles and chestnut husks, secateurs help with hips and sloes, and a stick is useful for parting nettles and testing the ground. Wash everything before you eat it — woodland fruit comes with dust, bird droppings and the occasional earwig.
Three rules cover most of it. Identify with certainty; if there is any doubt at all, leave it. Yew berries and their seeds are seriously toxic, and spurge laurel and mezereon, both found in or near woods, are dangerous too, so do not taste-test your way to confidence. Take only what you will use, and never strip a bush or a tree — the crop feeds dormice, birds and insects long before it feeds you. And know where you are: many reserves, SSSIs and private woods have their own rules about picking, while uprooting plants is another matter entirely, so ask the landowner or site manager if you are unsure.
Cook sloes, rowan and crab apples rather than eating them raw, and check with a pharmacist or doctor if you have allergies or a medical condition and are unsure about a particular fruit. Foraging is a long apprenticeship, and the pleasure is in the looking. A February walk that ends with nothing but a note of where the hazels are is still a good day's work.
