From changing patterns of frost and rainfall to increasing risks of summer heatwaves, climate change presents a unique set of challenges – and some opportunities – for gardeners. This week’s show is all about our increasingly variable weather and what it means for gardens, gardeners and our wildlife. Featuring weatherman and BBC broadcaster Peter Gibbs, WWF Head of Climate Change Gareth Redmond-King and RHS Gardening Advisor Nikki Barker.
