British shoppers may soon see sun-tanned cauliflowers, curly cucumbers, and knobbly potatoes on supermarket shelves as farmers contend with one of the most extreme growing seasons on record. Repeated heatwaves following a warmer-than-usual spring have led to predictions of the worst harvest since records began, according to farmers and industry experts.
The heat is not only reducing yields but also altering the appearance of produce. Retailers typically reject fruits and vegetables that fail to meet strict guidelines on size, shape, and color. However, with supplies under pressure, many are expected to relax these rules to prevent empty shelves.
Emilie Vanpoperingh, co-founder of Oddbox, a company that sells surplus produce rejected by supermarkets, said the discoloration in cauliflowers is "purely a cosmetic defect" and the taste is unaffected. Oddbox recently acquired 6,000 cauliflower heads that were too dark for supermarkets to sell. She noted that growers' water reserves are depleted, slowing growth of brassicas like cauliflower and broccoli, which could lead to shorter supplies.
Cucumbers are also being affected, with some bending into spirals due to stress from overheating in greenhouses. "Even if they get the irrigation then it's just extreme heat, which means the plant is not able to grow anymore," Vanpoperingh explained.
John Harper, a farmer in Worcestershire, has discarded more pak choi than usual this year due to tiny holes caused by flea beetles, which thrive in hot, dry conditions. With restrictions on pesticide use, net covers are his only defense. Supermarkets' strict cosmetic rules mean "one tiny little hole can render the plant useless," he said, though some have temporarily loosened the rules. Harper added that the vast majority of affected pak choi is still edible.
Potato farmer Lucy Munns from Cambridgeshire said the hot weather stunts growth, leading to oddly shaped tubers that supermarkets and chip shops wouldn't normally buy. "Trying to find people that will accept potatoes like that is very difficult. So that ultimately means a lot of wastage for us," she said, calling the waste "criminal." She assured that the potatoes are fine to eat, with the only difficulty being peeling them.
Supermarkets including Sainsbury's, Tesco, Morrisons, and Waitrose already have dedicated lines for wonky vegetables. Calum Kelly, Waitrose's produce technical manager, said in demanding weather conditions "we relax size and shape guidelines for key veg to avoid waste and provide more income to our growers and farmers." He noted that baking potatoes might be smaller than usual this harvest if the drought continues.
Andrew Opie, director of food and sustainability at the British Retail Consortium, said supermarkets are also importing more food from abroad as UK supplies run short. "Retailers face the dilemma of supporting British farmers, but also making sure that we, as customers, have what we expect to buy when we go in the shop," he said. "It's going to be a challenging period right through into the autumn."
As British summers become hotter and drier due to climate change, such seasons may become more frequent. Farmers may need to accept more waste, invest in better irrigation, or find ways to sell more wonky produce. Munns urged consumers to "be a bit less picky" about fresh produce, noting, "We've been too spoilt in the UK."
