Kathy Clugston hosts this week's gardening panel show, joined by Bob Flowerdew, Pippa Greenwood and James Wong to answer listeners' horticultural quandaries and queries. The panellists tackle questions on unhappy salad leaves, growing your own Christmas dinner and fragrant climbers for a pergola. They also share obscure gardening tips passed down from their elders. Away from the questions, garden designer Humaira Ikram explains how best to plant in dry conditions, and Peter Gibbs visits the heather garden at RHS Wisley with head gardener Matthew Pottage.
