Kathy Clugston and the panel are in Dumfries and Galloway. James Wong, Matthew Wilson and Christine Walkden answer questions from the audience. This week, the panellists discuss encouraging plants to grow in a stone garden wall. They also advise on over-wintering a fig tree and consider the best plant varieties for a garden with low drainage. Matt Biggs meets GQT listener Sarah Davison, who is blind. She guides Matt round her garden and shows him how sight isn't essential to gardening. Producer: Dan Cocker Assistant Producer: Rosie Merotra A Somethin' Else production for BBC Radio 4
