The heatwave has left strawberry and cherry farmers with a glut of crops, forcing them to sell off the fruits cheaper than normal.

The extra sunshine led to a growth spurt for both fruits across the country - including in Kent.

Alastair Brooks, managing director of Langdon Manor Farm near Faversham, says the weather during the spring through to the heatwave provided perfect growing conditions.

“Following a mild, settled spring, we have experienced prolonged sunshine, extra daylight, and very little rain in the last few weeks," he said.

“This has resulted in an abundance of healthy, perfectly ripe, extra sweet strawberries.

"After a wet jubilee weekend, we are excited to be able to finally celebrate the British strawberry season.”

To help prevent waste, Tesco is selling 1kg boxes at a discounted price.

Mr Brooks added: “With a few extra tonnes of strawberries being available we are thankful for Tesco’s support at this time.

“It allows us to minimise wastage and get more of the very best, high-quality and nutritious Driscoll’s Zara strawberries packed, picked and distributed to stores ready for consumers to enjoy.”

Tesco berries buying manager Laura Mitchell says many strawberry growers are seeing production levels about 10 to 15% higher than normal for this time of year.

“British shoppers are going through a tough time at the moment, and if there’s something that can put a big smile on faces right now, it’s being able to buy sweet, lush, British strawberries for less than normal," she said.

The 1kg boxes of strawberries will go on sale at more than 750 Tesco stores across the UK priced at £4. Kilo boxes of cherries will be sold for £5 at 850 stores.

Regular 400g punnets of cherries cost £3, so to buy 1kg would normally cost £7.50.

Last year, shoppers bought more than 87,000 tonnes of British strawberries. The industry is worth more than £769 million to the British economy, according to Kantar figures.

The heatwave has also resulted in higher than normal berry growth in Norfolk, Lancashire, Scotland and Herefordshire.
