Kathy Clugston hosts the horticultural programme featuring a group of gardening experts. This week's panellists are the ever-knowledgeable Chris Thorogood, Pippa Greenwood, and Bunny Guinness. The team marks the beginning of National Tree Week by sharing some potted tree ideas for a rooftop terrace, as well as offering advice for a student science project. Meanwhile, Bob Flowerdew has some top tips for looking after fruiting plants over winter, and we head up to Edinburgh as Kirsty Wilson tells us about two rather unusual plants, Dead Man's Fingers and the colourful Beautyberry.
