Peter Gibbs hosts a correspondence edition from the Chelsea Flower Show. Matthew Wilson, Pippa Greenwood and Bunny Guinness answer the questions from the postbag. The panellists are granted exclusive access to the greatest flower show in the world and, as they look around the show gardens at the Grand Pavilion, answer listeners' questions on layering and ailing orchids - among other matters. Peter Gibbs chats to GQT panellist and Gold Medal winner Chris Beardshaw about his award-winning garden and his inspiration for this year's design. And garden designer (and Chelsea Gold Medal winner from last year) Charlotte Harris takes a look at this year's show gardens, chatting through the "take home tips" that can be applied to a garden at home. Produced by Hannah Newton Assistant Producer: Laurence Bassett A Somethin' Else production for BBC Radio 4.
