Kathy Clugston and the horticultural panel are in Newcastle. Matt Biggs, Pippa Greenwood and James Wong answer the audience's questions. The panellists advise on growing rhubarb, suggest year-round border plants and discuss the difficulties of growing lemon trees. They also make colourful bush recommendations for a seaside garden. Away from the questions, James Wong visits Mark Ridsdill Smith, aka The Vertical Veg Man, to see his vegetable garden in Newcastle.
