Kathy Clugston hosts the horticultural programme with Bob Flowerdew, Anne Swithinbank and James Wong. This week, the panellists field questions from the audience on common gardening phrases from the 1950s, slow flowering plants, and the fiddly job of nurturing a bottle garden. Away from the questions, Peter Gibbs takes a trip to RHS Wisley's extensive Pelargonium collection and Kirsty Wilson waxes lyrical about her favourite tree, the Ginkgo biloba.
