Peter Gibbs presents the second of two programmes from the GQT annual Summer Garden Party at National Trust Mount Stewart in County Down, Northern Ireland. Christine Walkden, Matt Biggs, Pippa Greenwood and James Wong answer the audience's horticultural questions. The panellists advise on moss, getting rid of a hard-to-reach hop, and restoring an overgrown allotment. They also give odds on the likelihood of growing tomatoes outdoors on a patio in Coleraine. Throughout the programme, each panellist picks their favourite plants from the gardens at Mount Stewart and Matthew Wilson goes on a tour with Head Gardener Neil Porteus, discovering the history of the gardens and the pioneering work of Edith Vane-Tempest-Stewart, Lady Londonderry. Also, Christine Walkden and Bob Flowerdew get in and among the crowds to suggest some useful Take Home Tips. Produced by Hannah Newton Assistant Producer: Laurence Bassett A Somethin' Else production for BBC Radio 4.
