Reuters says because of the inclement weather in the UK. Farmers grow cumbers, plant peppers, aubergines, and tomatoes in vast greenhouses. Greenhouses use natural gas for heat, but after last year's surge in gas prices exacerbated by Russia's invasion of Ukraine last month, the crops have become uneconomical to produce. 

Trade body British Growers said the average cost to produce a cucumber in Britain before the energy crisis was around 25 pence, which is now more than doubled and set to hit 70 pence when higher energy prices fully kick in. 

"Gas prices being so sky-high, it's a worrying time," grower Tony Montalbano said. 

"All the years of us working hard to get to where we are, and then one year it could just all finish," Montalbano said.
