Growing lavender, success with agapanthus and healing through gardening

David travels to County Fermanagh, where he meets Vera Cassidy at Lavender Manor near Enniskillen. The venue is true to its name, and it is the ideal place to find out how to grow this wonderfully scented shrubby perennial. A few miles away in Lisnaskea, victims' charity SEFF has been using gardening as a form of therapy. The organisation has 44 allotment plots, many of which are used by people living with trauma. David meets some of the members, including Malcolm, who has hopes of winning a medal for some of his vegetables at a show. After a seven-year absence, Neil Porteous has returned to the National Trust's Mount Stewart as head gardener. He reveals some of his plans for the garden and takes time to enjoy the South African plants, including agapanthus and protea, that are performing well in late summer. Anna Hudson also joins David live in the studio to answer listeners' questions.
