Glasshouse salad body Lea Valley Growers tweeted yesterday:
Major increase in orders for #Leevalley growers, Poor Spanish weather = higher wholesale prices & caterers clearing supermarket shelves.
Several major supermarkets have been unable to supply crops such as leafy salads, spinach, broccoli and tomatoes, for which Spain is usually a major winter supplier to the UK market.
In a number of cases, supermarkets including Tesco, Morrison's and Waitrose, have restricted the number of purchases of such vegetables per person.
Meanwhile one Birmingham grower is offering a box of 12 iceberg lettuces via online market Gumtree for £50, or £4.17 each. His advert reads: "A box of a dozen Iceberg lettuce, freshly picked this morning. There are a national shortage of these beauties so the price is a little higher due to supply and demand."
