With the festive season in full swing, David heads to Montalto Estate in County Down for a winter walk with head gardener Lesley Heron. While Storm Bram has created some extra work, there’s still plenty to enjoy, including plants that bring colour and structure to the darkest months of the year. Also on the programme, David chats to Brendan Gilsenan at the National Botanic Gardens in Dublin about mistletoe — the seasonal plant romantics seek out at this time of year — and Maeve Bell explains why every garden should make room for a mahonia. Back in the studio, David is joined by garden expert Brendan Little, along with Katy Bell for her winter wildlife update. Email the programme at gardenerscorner@bbc.co.uk
