Joe Swift, Carol Klein and Adam Frost bring an exclusive look at the brand new RHS Chatsworth Flower Show. We meet leading designer Jo Thompson as she prepares her show garden with a difference. In the Floral Pavilion, Carol finds pioneering plants that have shaped the gardens of today and garden designer Arit Anderson looks to the future - meeting the team behind a garden built for the changing climate. Back at Longmeadow, Monty provides the ubiquitous jobs for the weekend.
