In Gardeners' Corner this week, David Maxwell visits the orchard at Glenarm Castle with Reg Maxwell and hears how to grow medlars, trees which give spring flowers, fruit and autumn colour. Also in the programme Helen Mark pays a return visit to Wendy Austin's garden in Donegal with Brendan Little who helped Wendy create her orchard last year. Neil Porteous and gardener Alan Ryder show David how the restoration of the old rose garden is coming along, tucked away in a hidden area behind Mountstewart and Cherry Townsend is this week's studio guest with lots of ideas on plants and flowers to brighten up the house in the lead up to Christmas.
