Autumn colour arrives, what to grow now and the backyard bargain garden

With warm colours all around, Gardeners’ Corner celebrates the arrival of autumn. At the National Trust’s Rowallane Gardens, David meets head gardener Claire McNally for a walk in the woods where Acers, Sorbus, Birch and Enkianthus are stealing the show. As this year’s harvest is gathered in, Amy Kelly is thinking ahead to what can be planted now for early crops next year. In Moira, David discovers a secret courtyard garden beside the oldest house in the village and he chats to Mary Reynolds about her journey from being the youngest ever winner of a gold medal at the Chelsea Flower Show to the founder of the ‘We are the ARK’ movement which campaigns to restore nature through native planting. In studio, David is joined by Mary Doris who has made best use of the apple and pear harvest. Contact the programme on gardenerscorner@bbc.co.uk
