Most growers have been carrying on as normal, with the main snag being the increased harvesting costs as the frost and snow slows the process down. But cauliflower growers said they were expecting significant crop losses over the Christmas period.
TH Clements commercial manager Richard Mowbray said: "You can harvest the other brassicas in frost but you get damage with cauliflower. The country's three main growing areas - Kent, Lincolnshire and Cornwall - have had continual frost for the past 10 days."
He added that traders may have difficulty sourcing extra supplies from Europe because it had also been bitten by the frost.
The Really Welsh company reported that it was still harvesting its leeks despite the cold temperatures and potato grower Solanum in Lincolnshire said it had been "doing well". Riverford Organic Vegetables has also managed to harvest its celeriac.
