Great British Gardens With Carol Klein

Channel 5, 9pm

The veteran gardener returns for a new eight-part run of the green-fingered show in which she visits gardens across the country to learn more about the sites and the people who keep them in pristine condition. She begins with a visit to Arundel Castle Gardens in West Sussex, where she investigates some of the rare plants grown there, as well as trying her hand at posy-making and pollinating peach trees.
