Kathy Clugston is joined by experts Matthew Wilson, Anne Swithinbank and Matt Biggs as they head to this year's RHS Chelsea Flower Show. To celebrate 75 years of the programme, for the first time ever, Gardeners' Question Time has its very own exhibit at the show. The exhibit, designed by Matthew Wilson and planted by the whole team, exemplifies all things GQT - from right plant, right place, to the joys of 'grow your own'. The panellists enjoy the GQT exhibit and answer questions from the postbag. They also catch up with Juliet Sargeant and finally see her designs come to life in the new Blue Peter Garden: Discover Soil. Meanwhile, roving reporter Peter Gibbs explores the showgrounds. He meets with exhibitors Jane Lyndsey from Tynings Climbers, Joanne Jackson and David Lloyd of Ottershaw Cacti and Chris Potts from Sienna Hosta.
