A full guide to blackberries: when they are in season, where to find them, how to pick them and what to cook with them

Save

Blackberry season, whether you're an experienced forager, weekend bramble picker, proud grower of cultivated blackberries, or simply someone who enjoys snacking on fresh berries from the shop, is a special time. Blackberries are a quintessential autumn fruit in the UK and no British autumn is complete without them. Understanding blackberry picking season and how to responsibly harvest them can make the growing, picking, cooking and eating of them even more rewarding.

When are blackberries in season?

The season for blackberries in the UK is August, September and early October, depending on the weather. They can be grown in the garden under netting, their canes trained along wires to produce fruit every year. For more details take a look at our How To Grow Blackberries guide.

These cultivated varieties, which also appear in shops in autumn, are large and juicy compared to the wild blackberries found in hedgerows at the same time of year. Wild blackberries, or brambles as they are sometimes known, are smaller and often tarter, but have the advantage of being free and requiring no tending or garden space.

According to ancient folklore, blackberries picked after Michaelmas Day (29th September) are cursed and have been, amongst other things, spat on by witches and/or Lucifer depending on which tale you read. Whilst the precise nature of the curse is open to interpretation, this date does roughly mark the point at which wild blackberries turn soft and mushy and are best left to the birds, so get out bramble picking before then!

Can you eat wild blackberries?

Yes, wild blackberries are perfectly safe to eat, provided you follow the guidelines set out below.

How to identify wild blackberries

Blackberries are relatively easy to recognise making them a great crop for beginner foragers. They have arching, thorny brambles that can reach up to 3 metres high, pale pink and white flowers that look like tiny wild roses (they are part of the same family) and clusters of juicy, dark berries. The leaves are dark green, serrated and oval and tend to cluster in groups of 3 or 5 around a short stem. However, always be sure you're harvesting from a blackberry bush and not other common hedgerow berries which may be poisonous. If in doubt, consult a local foraging guide or expert.

While you can buy large, juicy blackberries from the shops, there's nothing like getting sticky, juice-stained fingers and picking wild blackberries yourself from the hedgerows. Follow these tips for a fruitful harvesting experience:

1. Where to find wild blackberries

Blackberry brambles are very common and grow wild across Britain. They love to ramble undisturbed in the sunshine over tall structures
They can be found growing up trees and bushes in hedgerows, forests and the edges of woodlands
But they also grow in more urban spaces like the edges of playing fields, park hedges or along canal sides

2. How to choose the right location

Avoid blackberries growing near busy roads as the pollution may contaminate the berries
Only pick berries above dog height – no one wants blackberries that have been used as a toilet
Blackberries thrive in sunny spots. Look for brambles in open fields or near the edges of forests that face south or have a good amount of sunlight

3. When to pick blackberries

When is blackberry season in the UK? The season can begin as early as July if the weather is warm and sunny and can run until October if it remains dry but not so dry that the berries shrivel
How to spot a ripe blackberry: the berries transition from firm and red to plump, deep purple or black when they’re ready to be picked. Blackberries don’t ripen after picking so look for berries that are uniformly black, glossy, and slightly soft when gently squeezed. Avoid any that are red or pale purple, as they’ll be too tart. Ripe berries will pull away from the bramble easily. If you have to tug, it's not ready yet
The best time to pick blackberries: on a sunny morning as this ensures cooler temperatures and fresher, juicer and sweeter berries, but without them being parched by the midday sun

4. Dress appropriately

Wear long sleeves and trousers: blackberry bushes are notorious for their thorns, which can cause nasty scratches. Sturdy clothing protects you from prickles, potential insect bites and nettle rash
Sturdy shoes: since blackberries often grow in uneven terrain, wear walking shoes with good grip
Gloves: thin gardening gloves will protect your fingers from thorns and nettles and prevent them staining

5. Harvesting technique

Pick with hands only: do not cut brambles as this can harm wildlife habitat and may cause disease or damage the plant
Pull gently: ripe blackberries should come off the stem with minimal effort
Handle with care: blackberries are delicate and bruise easily
What to carry blackberries in: use a wide, shallow container to prevent berries at the bottom from being crushed whilst you forage. Something with a handle is especially convenient for carrying through fields

6. Storing them at home

Check for stowaways: leave blackberries spread out on kitchen paper in the garden for an hour so any bugs can crawl away
Should you wash blackberries? Submerging gently in cold water is best. Soaking the delicate berries or agitating them in water will bruise or burst them
Use immediately: wild blackberries are best eaten the day they are picked. Stew them with a little sugar and freeze until needed or make one of the recipes suggested below

Responsible foraging

Foraging is a fantastic way to connect with nature, but it comes with responsibilities to ensure the sustainability of wild spaces and respect for other foragers:

1. Ask permission

Some regions have specific rules about foraging on public or private lands. Always check if you need a permit or permission to forage, especially in parks or nature reserves
Always ask permission of the landowner before foraging, even if it's just a bramble on someone's garden wall

2. Leave no trace

Avoid trampling plants or disturbing surrounding vegetation
Take any rubbish with you, and avoid using plastic bags that can blow away in the wind
Don't pull brambles out of trees or damage the plant in any way

3. Harvest mindfully

Only take what you’ll use and leave enough berries for wildlife and other foragers
To prevent over-harvesting, don’t pick from the same patch too frequently
Hedgerows are a food source and habitat for many creatures, so take care not to disturb nests or step on burrows

Ways to cook with blackberries

Apple and blackberry crumble. Good Food

Wild blackberries often have a more robust, tangy flavour than cultivated varieties, making them a favourite for jams, pies, and syrups. Shop bought are good for cakes or just eating with yogurt for breakfast.

Crumbles – the most traditional way to serve blackberries. This easy apple and blackberry crumble recipe from our friends at Good Food is a favourite because the crumble is baked separately making for an extra crunchy topping
Jam – blackberries are rarely sickly sweet so they are perfect to balance a bramble or hedgerow jam. Or put them centre stage as here in this blackberry jam from the Good Food team
With venison – blackberries pair brilliantly with venison. Try pickling them in pickling liquor made from equal amounts of cider vinegar and honey for 10 minutes then serving with rare venison steak, or make this tart and glossy blackberry sauce from the Good Food team
Salad – a few tart blackberries will enliven a wintery salad of chicken and bitter leaves
Cakes – little bursts of juicy blackberries take easy bakes to the next level. The Good Food team suggest this super simple blackberry and apple loaf, blackberry and hazelnut flapjack with extra jammyness, or this showstopping blackberry and orange cake which is ideal for autumn birthdays
