Peter Gibbs and the panel are on the North Riding Coast in Yorkshire. Bunny Guinness, Bob Flowerdew and Matthew Pottage answer the horticultural questions. This week, the team tackles questions on judging a gardening competition, planting in stone planters and adapting with the changes in weather patterns. The panellists also discuss how best to utilise a greenhouse in autumn and winter months. Away from the questions, Matt Biggs visits 99-year-old Christian Lamb, author and plant-hunter, at her home in London.
