How do you revive a banana plant? Can you encourage wild orchids to grow in your garden? Would you accept a kitchen sink as the top prize of a gardening competition?  In Ditchling to answer these questions and more in front of a live audience are Peter Gibbs and this week’s panel - garden designer Juliet Sargeant, pests and diseases expert Pippa Greenwood and Matthew Pottage, Curator at RHS Wisley.  Beyond the questions, James Wong educates us on the science behind the effects of music on plants.   Producer: Dominic Tyerman Assistant Producer: Dulcie Whadcock Executive Producer: Louisa Field  A Somethin' Else production for BBC Radio 4
