Peter Gibbs hosts the horticultural programme featuring the ever-knowledgable Kirsty Wilson, Matt Biggs, and Anne Swithinbank fielding questions from listeners across the country. This week, the panellists share their ideas on nature-based solutions to flooding, bestow tips on splitting dahlia tubers and offer some inspiration for growing in hanging baskets and containers, with sustainability in-mind. Beyond the questions, Claire Ratinon visits the Sowing Roots: Caribbean Garden Heritage in London exhibition at the Garden Museum and talks to one of the curators, Dr Ekua McMorris, and contributor Ras Prince Morgan, about the important gardening practices brought to Britain with the Windrush generation. And, Dr Chris Thorogood transports us to a remote tract of dunes on La Graciosa island in Spain, as he hunts for a rare botanical marvel, the cynomorium coccineum.
