Can a pair of underpants tell you how healthy your soil is? What is toxic squash syndrome? And just why does Viburnum tinus smell like wet dog and poo to some people? Joining Peter Gibbs to answer these questions in front of a live audience in Banstead, Surrey, are plant and diseases expert Pippa Greenwood, garden designer Bunny Guinness and 'grow your own' expert Bob Flowerdew. Also on the programme, Bob Flowerdew offers up a masterclass on green manuring.
