Peter Gibbs chairs the horticultural programme with Christine Walkden, Matthew Pottage and Anne Swithinbank on the panel, ready and waiting for questions sent in by listeners via email and social media. The panellists discuss ways to support mammals in our gardens following news that a quarter of native mammals are now at risk of extinction in the UK. They also attempt to identify a mysterious 'sausage growing plant', suggest ways to incorporate gardening into primary school learning, and recommend the best tropical palms to add a touch of Brazilian rainforest to a new home. Aside from the questions, Peter Gibbs interviews the new President of the RHS, Keith Weed, and Pippa Greenwood speaks to Professor Nicola Spence, Chief Plant Health Officer at DEFRA, about biosecurity and suspect seeds.
