In this Gardeners’ Corner special to mark the coronation, presenter David Maxwell travels to the private garden of King Charles III in Gloucestershire. He’s shown around by Derry man, Brian Corr who learnt his gardening trade in Northern Ireland before becoming Head of Gardens at the King's Highgrove Estate. David explores the different areas of this organic garden which the King has been hands on in developing since he bought the property as Prince of Wales in 1980. Now under the stewardship of the Prince’s Foundation charity, David finds out how the estate is being opened up to the public and used as a showcase for traditional skills and crafts. And he chats to Royal florist Shane Connolly who shares the King’s passion for sustainability and is providing the floral backdrop for the coronation.
