Kathy Clugston and the panel are in the village of Ludlow. Fielding gardening questions from the audience this week are Bunny Guinness, Matthew Pottage and Matt Biggs. From old wives' tales to No Mow May, the team covers good ground in this week's GQT. Bunny, Matthew and Matt offer their guidance on growing bonsai - which species make for the best results? They also suggest tips for lifting the canopy of a cherry tree and share some spectacular design ideas for planting in alleyways. Beyond the questions, and in honour of National Plant Health week 2022, Pippa Greenwood visits the Royal Botanic Gardens, Kew to view their secret weapon against unwelcome plant pests.
