Horticultural programme featuring a group of gardening experts. Chairing this week is Peter Gibbs, and answering your questions are Bunny Guinness, Bob Flowerdew, and Matthew Pottage. As judging commences for this year's RHS Britain in Bloom, Peter speaks with local Stamford in Bloom coordinator Ann Ellis about what they've done to make Stamford a greener place. In the hall, the panellists answer questions on how best to secure a climbing rose to a wall, as well as giving advice on ivy that's getting out of control. They also explain when to prune a hydrangea, and how to help a variegated plant that is reverting. Away from the questions, Dr Chris Thorogood speaks to Beverley Glover at Cambridge Botanic Garden to find out why bees are attracted to certain plants.
