Late Summer Is Blackberry Time

By the middle of August the hedgerows are sagging under their own weight. What began in July as tight knots of green and pink has ripened into the deep, dusty black of a proper British blackberry, and for a few precious weeks the countryside offers one of the great free harvests of the year.

Brambles grow almost everywhere here: along field boundaries, in the sunny gaps of woodland rides, on scrubby waste ground, and in the tangled hedges that line our footpaths. Picking a punnet of your own is a small, satisfying act of attention to the season. It is also something worth doing properly, both for your own safety and for the wildlife that depends on the same fruit.

Ask First: Permission and the Law

The first rule of foraging is simple: only pick where you are allowed to pick. In England and Wales, the Theft Act 1968 makes clear that picking wild fruit growing on another person's land for your own consumption is not theft, but that does not give you the right to wander anywhere you like. A public footpath gives you the right to walk along it, not to leave it, and not to help yourself from the fields on either side. In Scotland, access rights under the Land Reform (Scotland) Act 2003 permit picking wild fruit for personal use, with responsibilities attached.

Byelaws vary. Many nature reserves, Sites of Special Scientific Interest, country parks and trust-owned estates restrict or prohibit foraging. If a hedge belongs to a farm, a golf course or a private garden, ask. Most landowners are perfectly happy for you to take a modest amount from a roadside verge for your own tea, and a two-second conversation avoids a great deal of awkwardness.

Choose Your Spot Carefully

Not every heavy bush is a good one. Some places to walk past:

• Hedgerows beside busy roads, where exhaust particulates and tyre dust settle on the fruit. Walk at least 50 metres from a main road before you start picking.
• Sprayed field margins. If the grass beneath the hedge is suspiciously uniform and weed-free, move on.
• Bushes at dog height. Anything between ankle and knee level is fair game for passing dogs, and best left alone.
• Field edges where livestock graze, unless you know the farmer's spraying and worming regime.
• Old industrial land, railway sidings and anywhere the soil may be contaminated.

Pick at waist height or above where you can. Brambles are thorny, so wear long sleeves, thick trousers and gloves, and check yourself for ticks afterwards, as late summer is peak tick season in rough grass and scrub.

Picking Well and Leaving Plenty

A ripe blackberry comes away with the gentlest roll of the thumb; if it needs a tug, it is not ready. Red berries are hard and sour, green ones are pointless. Take a shallow container rather than a deep bag, so the fruit does not crush under its own weight.

Work gently. Do not drag branches down or snap them off; brambles are slow to regrow, and the tangled structure is what makes a hedge good for everything else. Look before you reach, as late-nesting pigeons and the occasional thrush still use the cover in August.

Above all, leave plenty behind. Blackberries are a critical late-summer larder for blackbirds, song thrushes and the first arriving redwings and fieldfares, as well as for dormice, badgers, foxes, wood mice and bats. Take from the middle of a bush, leave the highest and lowest fruit, and never strip a hedge bare. A decent guide is to take no more than a third of what you find, and to move on rather than returning to the same bush day after day.

From Hedge to Kitchen

Wash everything before it goes near your mouth. Plunge the berries into cold water, lift them out, and repeat once or twice; a little salt or a splash of vinegar in the first soak encourages any small residents to leave. Drain on a tea towel and use within a day or two.

If you are picking in quantity, freeze the berries spread out on a tray first, then bag them once solid. They keep for a year and drop straight into crumbles and jam. Cooked blackberries are the safer option if you are at all unsure about the source. Discard any fruit with grey mould or an off smell, and never eat a hedgerow berry you cannot identify with certainty.

Bramble Lore and Countryside Heritage

Brambles have been part of the British landscape for a very long time. They were managed in medieval hedges, woven into field boundaries during the eighteenth- and nineteenth-century Enclosures, and used for dyeing wool, flavouring country wine and marking the turn of the year. In many parts of the country, old tradition holds that blackberries should not be picked after Michaelmas on 29 September; the practical reason is simply that late berries are watery and mouldy.

However you treat the folklore, foraging is a way of reading the countryside rather than merely walking through it. Pick with permission, pick with care, leave the hedge richer than you found it, and the season's small dark reward will taste all the better for it.
