It's Christmas, and Countryfile has received a very special invitation to visit Highgrove Gardens, which surround the private residence of Their Majesties King Charles III and Queen Camilla. Matt Baker, Margherita Taylor and Adam Henson meet staff from His Majesty's charity The King's Foundation, who manage Highgrove and transform it into a festive wonderland each Christmas, all while staying true to His Majesty's passion for nature and sustainability. Matt joins Highgrove's garden team to harvest the King's brussels sprouts and meets students taking part in The King's Foundation education programmes using British timber, and Adam joins a local farmer shepherding his Shropshire sheep onto the estate's wildflower meadow for grazing. To finish the episode, there's a taste of a Highgrove Christmas, as the royal chef prepares a delicious feast of turkey and brussels sprouts.
