Every year the RHS Chelsea Flower Show offers new ideas for planting in small spaces, and that's the focus for this programme. Andy Sturgeon visits a tiny garden inspired by one of the Kensington Roof Gardens in London, while Rachel de Thame has take-home advice for planting combinations for containers. It is also time to celebrate the RHS Young Florist of the Year as British Florists Association events director Dennis van Wonderen demonstrates how to make a floral party dress as part of the competition challenge, and then Nicki Chapman chats to the jubilant winner.
