Gardeners' Corner

As the leaves continue to fall, presenter David Maxwell visits one of most important historic gardens on the island of Ireland. The arboretum and walled garden within Castlewellan Forest Park has dozens of champion trees and it’s a garden getting a facelift. Alwyn Sinnamon reveals the work going on to restore some of the gardens 18th century features, as well as the discovery of lost garden. Also on the programme, in Glenarm Castle’s walled garden Neil Porteous is preparing the bananas for winter and on up the east Antrim coast Una Quinn is part of the National Trust team which has restored and reopened Cushendun’s village green. David is joined live in studio by expert Ann Fitzsimmons. Contact the programme on gardenerscorner@bbc.co.uk
