Peter Gibbs and the team are at Herstmonceux Castle, East Sussex. Juliet Sargeant, Matt Biggs and Matthew Pottage are this weeks' panellists, ready to answer your gardening questions.

Led by Herstmonceux's head gardener Guy Lucas, the team explores the castle grounds and learns about the sustainable gardening practices adopted in recent years.

The panellists also tackle questions from listeners, including suggestions for what to plant around a thatched cottage, and when to prune plants that are still in flower in the winter.
