Adam Nicolson, Nigel's son and the resident donor after his father's death, and his wife Sarah Raven, have sought to restore a form of traditional Wealden agriculture to Sissinghurst Farm. Their work to reunite the garden with its wider landscape is described in Adam's 2008 book, "Sissinghurst: An Unfinished History", which won the Ondaatje Prize, and was the subject of a BBC Four documentary, "Sissinghurst", in 2009. Their efforts have generated some controversy, reflecting the tension between the demands of traditional agricultural practices and the requirements of a major tourism destination in the 21st century.
