A cab driver, whose exotic North London garden is packed with palms and bursting with bamboos, joins the amateur horticulturalists. Ann-Marie enters the urban jungle at Pat Wallace's Islington flat, where he and his wife Sandy have lived for 20 years. Pat gets Ann-Marie's advice on layout, design and the position of a new eight-foot fern. After helping clear away a grassy mound, at the Guernsey home of Liz and Rod Collenette, Monty Don's thoughts turn to planting raised beds where the mound once stood. Together Liz and Monty tackle the task. Carol Klein returns to South Devon to see Adrian and Debbie Taylor, who have been suitably inspired by their trip to the Chelsea Flower Show. With Carol's help, they set about planting scented flowers in the terraced bed using seedlings that Debbie has propagated herself.
