More highlights from the RHS Flower Show, Tatton Park, as Monty Don, Joe Swift and the team review the gardens created by the finalists in the RHS Young Designer of the Year competition and reveal the winners of the prestigious Best Show Garden and Best Back to Back Garden. Arit Anderson looks at a garden designed to adapt to our changing climate, whilst Carol Klein investigates the rise of cacti and succulents as the must-have house plants.
