Families loading up tupperware boxes to pick wild blackberries have been warned that the summer tradition can end in a fine of up to £300 if done irresponsibly.
August, September and early October are usually the best months to pick the fruit, but this year's constant heatwaves have caused blackberries to fruit weeks earlier than normal, with foragers already heading out to roadsides, fields and forests.
What do the rules say?
Arbtech, an ecology consultancy, warns that while picking wild blackberries is generally permitted under the Theft Act 1968, there are restrictions that could land pickers with a fixed penalty.
"Under the Theft Act 1968, picking wild flowers, fruit, fungi, and foliage - known as the 'Four F's' - is generally permitted, but with some restrictions," Arbtech explains.
"People are allowed to forage blackberries for personal use, provided they don't uproot the plant. That means gathering blackberries from hedgerows and commons is generally legal, as long as they're not sold for profit."
When can picking lead to a fine?
Picking on private land without the owner's consent could be classed as trespassing, and many protected areas such as nature reserves, Sites of Special Scientific Interest (SSSIs) and some Royal Parks have bylaws banning foraging altogether.
"If you get caught picking blackberries where you're not allowed, it doesn't matter how little you took, you could still face a fixed penalty which in some cases can range from around £100 to £300."
Stripping bushes completely bare or trampling surrounding vegetation can cause long-term harm to local ecosystems and can be a criminal offence if done irresponsibly, Arbtech warns.
How to forage sustainably
The experts say sustainable foraging is essential to protect wildlife and plant health. Berries should be picked sparingly, with plenty left behind for birds and other animals, and care must be taken not to damage surrounding habitats.
A spokesperson for Arbtech said: "Blackberry picking is a brilliant way to enjoy the outdoors and connect with nature, but it's important to remember that we're not the only ones who rely on them.
"Think of hedgerows like wildlife supermarkets – birds, mammals and insects all depend on those berries for food.
"So if we take too much or damage the plants, we're removing a vital resource.
"The golden rule is to pick lightly, leave plenty behind, and always check whether you're allowed to forage in that spot because in some places it's not just bad etiquette, it's against the law!"
