Kathy Clugston and the team of gardening experts are in East Dorset. Pippa Greenwood, Bob Flowerdew and Anne Swithenbank answer the audience's questions. This week the panellists advise on vertical gardening, bringing an Apple Tree back to life, and what to do with a tree stump. They also discuss what may be wrong with a plum tree and whether or not there is a disease on a hydrangea. Matt Biggs visits Peter and Cecilia Boycott at their home in Norfolk to see their alpine plant collection and talk about the returning trend for rockeries.
