When should we prune roses? What plants grow well in rubble and grass? What's infecting my Prunus avium?

Peter Gibbs and a team of horticultural experts are led on a guided tour of Regent's Park in London, while dipping into the GQT postbag to answer your gardening conundrums.

Leading the tour is head gardener and fellow GQT panellist Matthew Pottage, who's also joined by pest and disease expert Pippa Greenwood and head gardener Ashley Edwards.

Later in the programme, head gardeners Anna Rafal and Anne Tuomisto offer advice on pruning roses and designing a Mediterranean garden, as well as winter tidying with hibernating animals in mind.
