Which plants should I avoid that are prone to spreading across chalky grassland? Any tips on growing tropical canna plants in the warmest corner of my garden? What’s the panel’s oldest and favourite gardening garment? Peter Gibbs and a panel of horticultural experts provide some much needed advice to an audience in Pewsey. On the panel this week are pest and disease expert Pippa Greenwood, house plant specialist Anne Swithinbank and award winning garden designer Chris Beardshaw. Later in the programme, regular panellist Kirsty Wilson explores the history of the thistle plant as well as its significance to Scotland's national rugby union team, as this year's Six Nations Championship continues.
