Peter Gibbs hosts this week's gardening Q&A, with a panel of green fingered experts answering questions sent in by listeners via social media and email. Matt Biggs, Pippa Greenwood and Matthew Pottage tackle the queries, from making your garden design coherent, to the best lettuce to grow for your loved one. Away from the questions, Juliet Sargeant pays homage to the unsung hero of gardening, and Alex Young gives a refresher course in re-potting your houseplants.
