How can I get rid of slugs without using pesticides? Will rhododendrons grow on chalky soil? Should we remove dead trees or leave them for wildlife? Joining Peter Gibbs to answer these questions and more in front of a live audience in Tring are pest and disease expert Pippa Greenwood, plantsman Matt Biggs, and garden designer Juliet Sargeant. Also on the programme, Pippa Greenwood visits her old lab at the RHS Wisley Plant Science Laboratory which will shortly open its doors to the public to showcase past and present research.
