There is a growing disconnection between the food that we eat and how it is grown. Occasionally the newspapers will run stories about how children think tomatoes are made with the cellophane wrapper already there, or that pineapples are made in a factory already in cubes. As home gardeners with a keen interest in growing fruit and veg, we may well scoff at such stories – we know all too well how crops are grown. But I’ll wager that for many of you, the only experience of hazelnuts is out of a jar of Nutella, or as a flavouring to your morning latte.
