Kathy Clugston hosts the gardening panel show, with Pippa Greenwood, Chris Beardshaw and Matt Biggs joining her to answer questions sent in by listeners. This week, the team discusses how to add a water source to your garden, which plants are best for a living wall, and an impressive amount of train-related plant names. Away from the questions, Humaira Ikram explains how to keep your garden pet-safe and Chris Thorogood investigates the deceptive nature of the orchid.
