Gardeners' Question Time

Peter Gibbs and the panel are in West Maldon, Essex. Christine Walkden, Bob Flowerdew, and James Wong are answering the horticultural questions. This week the panellists puzzle over a mimosa that won't flower and try to diagnose a poorly potted olive tree. They also suggest some brilliant evergreen trees to replace a topiaried conifer. Away from the questions, James Wong heads to Kew where he speaks with researcher Dr James Borrell about a banana-like plant that has the potential to feed millions.
