Kathy Clugston and the panel are at the British Library, London. James Wong, Anne Swithinbank and Bob Flowerdew answer the audience's horticultural queries. This week, the panellists help ensure tomatoes are perfectly ripe for a horticultural show, discuss what may be going wrong with some fig trees, and debate the best kiwi fruit variety to grow. They also advise on growing turnips and the best plants for a green roof. Matt Biggs meets British Library curators Julian Harrison and Maddie Smith who have brought along some horticultural classics from within the British Library archives.
