Peter Gibbs and the panel are in Bristol. Bob Flowerdew, Anne Swithinbank and Pippa Greenwood answer this week's questions. The panellists assist a fire performer with an ailing aloe vera, encourage a struggling chilli grower, and advise on getting the best out of a young pineapple. They also offer up ideas for improving air circulation in a cramped garden and have fun with their most amusing plant names. Anne Swithinbank visits Nick Ray from Seeds of Change to unearth the fascinating story of Bristol's ballast plants.
