Some UK supermarkets have run out of peppers after a cold snap in Europe led to a shortage.
Unseasonably cold weather in Spain slowed down the growing of peppers, leading to Morrisons limiting purchases to two per customer.
The supermarket said it is hoping to lift the cap in the next week or so because supplies are improving.
Waitrose, which has also been hit by supply problems, said it is working hard with suppliers to get a full range back on shelves and expects stock levels to stabilise in the coming weeks as the UK moves into its growing season.
British Retail Consortium director of food and sustainability Andrew Opie said: “Difficult weather conditions in the south of Europe disrupted harvest for some fruit and vegetables, including peppers.
“A few stores have implemented temporary limits on how much customers can buy to ensure availability for everyone.
“However, availability should improve for those impacted in the coming weeks as we enter UK growing season.”
Supermarkets were forced to ration a range of fruit and vegetables earlier this year due to poor weather in Europe and Africa leading to shortages.
Shoppers started seeing shortages of tomatoes on about February 20, with retailers saying a combination of bad weather and related transport issues in north Africa and Europe were causing significant supply problems.
The shortages spread to other products, leaving shelves bare of fresh produce items, including cucumbers, peppers and lettuce.
Production problems in Morocco began in January with unusually cold night temperatures affecting tomato ripening.
Supplies from Britain’s other major winter source, Spain, were also badly affected by weather.
At the time, the National Farmers’ Union (NFU) said shortages of some fruit and vegetables in UK supermarkets could be “the tip of the iceberg”.
Deputy president Tom Bradshaw said a reliance on imports had left the UK vulnerable to “shock weather events”.
