Farmers across the UK are facing one of the driest and hottest growing seasons on record, resulting in predictions of the worst harvest since records began. Retailers may be forced to loosen their strict guidelines on size, shape, and colour due to supply pressure, which could lead to shoppers seeing smaller or wonkier vegetables on store shelves. According to a co-founder of Oddbox, a subscription company that sells surplus produce, the affected cauliflower is "purely a cosmetic defect" and still tastes the same. Growers are reporting depleted water reserves, leading to slower growth in cauliflower and broccoli supplies.

Would you buy a cauliflower that looks like it's been sunburnt or a cucumber that's curled back on itself?
asserted
that → publish → itself
Farmers across the UK are grappling with one of the driest, hottest growing seasons in decades.
asserted
Farmers → grapple → decades
Repeated heatwaves after a warmer than usual spring have led to predictions of the worst harvest since records began.
asserted
records → repeat → harvest
The heat is not only affecting how much produce is grown, but also how it looks.
asserted
it → affect → ?
Retailers usually reject fruit and vegetables that don't meet strict guidelines on size, shape and colour.
asserted
that → reject → size
But with supplies under pressure, many are now expected to loosen those rules rather than risk empty shelves.
asserted
many → expect → shelves
That means shoppers could start seeing smaller, wonkier or oddly coloured veg on the shelves in the coming weeks - and sellers and growers say it's still good to eat.
uncertain
it → mean → weeks
'Sun-tanned' cauliflowers
Cauliflower is one of the most affected vegetables in hot weather because it needs lots of water.
asserted
it → need → water
Its heads are usually shielded from sunlight by the leaves, but in this year more light is reaching them and turning them yellow.
asserted
light → shield → them
Emilie Vanpoperinghe, co-founder of Oddbox, a subscription company that sells surplus produce that supermarkets reject, said it is "purely a cosmetic defect" and the plants taste exactly the same.
asserted
plants → sell → that
She said Oddbox acquired 6,000 cauliflower heads last week that were too dark for supermarkets to sell.
asserted
supermarkets → say → heads
Growers are reporting that their water reserves are depleted, Vanpoperinghe said, which means the cauliflower and broccoli family of brassicas will experience slower growth, leading to shorter supplies.
asserted
family → report → supplies
That short supply means retailers may soon start stocking "sun-tanned" cauliflower because "their biggest nightmare is empty shelves", she said.
uncertain
she → mean → cauliflower
"They want to make sure that they've got availability of produce all the time."
asserted
they → want → produce
Growers are also reporting cucumbers that are coming out misshapen, with some bending back into a spiral.
asserted
some → report → spiral
That is because the plants are grown in greenhouses which overheat in the high outdoor temperatures, causing the plants to become stressed, Vanpoperinghe said.
"Even if they get the irrigation then it's just extreme heat, which means the plant is not able to grow anymore."
Holey pak choi
John Harper, a farmer in Worcestershire, grows pak choi for Sainsbury's, Aldi and Co-op, and has discarded more produce than usual this year because of tiny holes made by pests.
Flea beetles thrive in hot, dry conditions, and farmers are no longer allowed to use as many pesticides as before, meaning net covers are Harper's only defence.
asserted
covers → grow → pesticides
Supermarkets' strict cosmetic rules mean "one tiny little hole can render the plant useless", he said, but some have temporarily loosened the rules.
asserted
some → mean → rules
"We've been working with them through this hot period and in general they sort of get it," he added.
asserted
he → work → it
Harper said the vast majority of affected pak choi is still edible - even if "it seems to be quite tasty" for the beetles too.
asserted
it → say → beetles
Lucy Munns, a potato farmer in Cambridgeshire, said the hot weather will stunt the root vegetable's growth, leading to oddly shaped tubers that supermarkets and chip shops, which she supplies, wouldn't normally buy.
asserted
she → say → which
When the weather gets cooler after a hot period, instead of the main potato tuber growing "it tends to grow a little knobble on the end".
asserted
it → get → end
"Trying to find people that will accept potatoes like that is very difficult.
asserted
that → try → that
So that ultimately means a lot of wastage for us," Munns added.
asserted
Munns → mean → us
"It's criminal, to be honest, to be chucking that much food away.
asserted
It → chuck → food
Those "knobbly and misshapen potatoes" however are absolutely fine to eat, she said.
asserted
she → eat → ?
"The only difficulty is peeling them, but just cut the knobbly bit off and peel it separately."
asserted
difficulty → peel → it
Supermarkets including Sainsbury's, Tesco, Morrisons and Waitrose already have dedicated lines for wonky vegetables.
asserted
Supermarkets → include → 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".
asserted
we → say → growers
"Baking potatoes might be a little smaller than usual this harvest if the drought continues.
uncertain
drought → bake → potatoes
All these veg still taste great, but like many of us in a heatwave, they might just look a little less than perfect.
uncertain
they → taste → heatwave
Not every gap can be filled this way though.
asserted
gap → fill → ?
Andrew Opie, the director of food and sustainability at the British Retail Consortium, said supermarkets are also importing more food from abroad as UK supplies run short.
asserted
supplies → say → food
"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.
asserted
he → face → shop
"It's going to be a challenging period right through into the autumn.
asserted
It → go → autumn
We're hearing potentially it could affect things like cherries as well.
uncertain
it → hear → cherries
"
British summers are getting hotter and drier as the climate changes and heatwaves like this one are becoming more frequent.
asserted
heatwaves → get → one
That means a season like this one may become less of a one-off, and more of a preview of what British farming has to deal with regularly.
uncertain
farming → mean → what
Many farmers will either have to accept more waste, invest in better irrigation and water storage systems, or find a way to sell more wonky produce to consumers.
asserted
farmers → have → consumers
Munns, the potato farmer, said more people should try buying imperfect veg if they see it in the supermarket aisle this year.
asserted
they → say → aisle
People should "be a bit less picky" about fresh produce, she said.
asserted
she → say → produce
