Gardening on a slightly larger scale is practised by Hugh Cavendish, Lord Cavendish of Furness. In a Time to Plant: Life and Gardening at Holker (Frances Lincoln, £25), he has composed an entirely sui generis book, describing his life on his ancestral estate of 17,000 acres in Cumbria which he inherited when he was in his early thirties, until then working ineffectually in the City. For 40 years now, with his wife Grania, who has taken the fine photos that illustrate the book, he has remade the garden, planting rare trees and a wildflower meadow, creating a cascade and a labyrinth. But grand as these schemes are, he remains a hands-on gardener: “I know with absolute certainty that I am almost incapable of understanding a plant until I have become physically involved with it; and having handled it, I become conscious of a feeling of wishing to protect it.” Delightful: a book Lord Emsworth might have written if he had preferred trees to pigs.
