Kathy Clugston is at Chelsea Flower Show for a correspondence edition of the show. Matthew Wilson, Pippa Greenwood, and Anne Swithinbank are on hand to answer questions from the GQT inbox, postbag and social media. The panellists recommend alpines to grow between patio stones, advise on moving and replacing a pond, and consider what to think about when buying a new greenhouse. They also discuss suitable indoor plants for an office, and suggest ways to get a lemon tree to bear fruit. In between the questions, the panellists bump into some familiar faces at the flower show, stopping to chat to Chris Beardshaw about his show garden, and Daniel and Joanne Jackson about their cacti and succulent stand.
