Climate resilient gardens are a feature of this month's Chelsea Flower Show, but how can the experts help the typical British gardener prepare for the future? To find out, botanist James Wong asks whether the way we garden could protect us against the effects of climate change, and if we can protect our gardens against more unpredictable weather patterns? James joins Chelsea designer Tom Massey as he chooses plants for a mould breaking show garden. He learns tips for dealing with more unpredictable conditions at the Royal Horticultural Society's flagship Wisley garden, and from climate savvy gardener Kim Stoddart in West Wales. In the heart of London, amid the brutalist concrete of the Barbican centre, James meets Professor Nigel Dunnett, and considers how plants could make human habitats more liveable during heatwaves and heavy rain.Producer: Sarah Swadling
