Horticultural programme featuring a group of gardening experts. In the chair this week is Peter Gibbs, and he's joined by experts Bob Flowerdew, Matthew Pottage and Bunny Guinness. This week the panel are on Bunny's home turf in the historic town of Stamford. They explain what to do with an overgrown tulip tree, and how to safely plant out runner beans. They also recommend some plants for a Mexican themed garden, and suggest ideas for what to do with a glut of loofah plants. Away from the questions Matthew takes a trip up the road to Bunny's garden, and learns about her new rose meadow project.
