What makes a good hedge and is there still time for a trim before winter? That’s just two of the questions David Maxwell and his experts guests will tackle in this week’s gardening programme. David also visits the South Eastern Regional College’s Holywood campus where they have launched their new wellbeing garden. Born in the lockdown, Claire Dunwoody tells David it’s future is community focused. Also on the programme, a new woodland walk is under construction at Glenarm Castle estate. David gets a sneak preview on what visitors will find come next spring. And Averil Milligan and Maurice Parkinson will join David live to answer questions from listeners.
