With the leaves gone it’s all about colourful stem colour on Gardeners’ Corner this week. David meets artist Heather McDermott who loves willow more than any other plant and works with it every day. She thinks more of us should have our own ‘Salley’ gardens so we have this useful crop which can be used to make free plant supports and fences. Also on the programme, how a handful of soil has more life in it than there are people on the planet and celebrating Garvagh man Andrew McClarty who has been using gardening to raise funds for charity for 25 years. Ann Fitzsimmons will join David live in studio to answer questions. Contact the programme on gardenerscorner@bbc.co.uk
