This week we're going back to nature at the world's biggest annual flower show. Designer Jo Thompson explains how she's gone wild with the BBC Springwatch Garden, Dave Green shares his meditative spaces in the Stop and Pause Garden and Matthew Childs contemplates new approaches to energy use in the Smart Meter Garden.

Plus we visit the RHS Back to Nature Garden (co-designed by HRH The Duchess of Cambridge, Andrée Davies and Adam White), discover a drought-tolerant garden in memory of horticultural hero Beth Chatto, meet community allotmenteers and hear a surprising botanical cocktail recipe from food writer Mark Diacono.
