With two weeks until the coronation, David visits a garden under construction to mark the event. Diarmuid Gavin’s bold design for The King’s Coronation garden will soon be an eye catching attraction at Hazelbank Park on the shores of Belfast Lough. Among those helping to get the garden finished on time are some students from CAFRE’s Greenmount campus. Also on the programme, Helen Mark visits the National Trust’s Florence Court where Ian Marshall and his volunteers are busy planting broad beans and potatoes in the kitchen garden. Jekka McVicar reveals her favourite herb for April and Reg Maxwell joins David in studio to answer questions and provide some seasonal inspiration for the gardener at home.
