Once every big house had its walled kitchen garden. In an age before imports and deep freezers, the head gardener and his staff had to supply the household throughout the year. Today most walled gardens lie derelict. To uncover the secrets of the great Victorian gardeners, restoration was begun on a kitchen garden in Berkshire. With the help of a rich legacy of gardening manuals, plans were made to grow vegetables and fruit similar to the Victorians and to revive forgotten crafts and skills - hoping to find out what it was like to feed a large country estate without modern technology and well-stocked supermarkets.
