Faced with rising temperatures, farmers have to plan tree crops that can withstand a hotter climate. Already, the UK growing season has lengthened by about a month since 1900. By mid-century, maximum temperatures in southern counties will break through the 40C (104F) level, and by 2080, the South East could be as hot as Bordeaux is now.With that change in focus, Britain is thinking about olives.
Britain warms to the taste for home-grown olives-News-Weather-TimesOnline:
The olive trees were imported from Tuscany, where they experience frost and snow in winter and high temperatures in summer. Drainage on the heavy Devon soil had to be improved, because olive trees are used to growing in thin, rocky soils. But with the rapidly warming climate, it is hoped the first commercial British olive crop will be harvested in a few years’ time.
Perhaps even more surprising, two commercial olive groves have been planted much further north, in Wales and Shropshire. Three hundred Italian olive trees were planted at Wroxeter Roman Vineyard, near Shrewsbury, and the first Welsh olive grove was begun in Anglesey.
