Prairie-style planting, daffodils, layering and the green prescription

In this week's Gardeners' Corner, David Maxwell meets up with Cherry Townsend to explore prairie-style planting. He heads to Esker Farm Daffodils in County Tyrone where Dave and Julie Hardy have been preparing bulbs all summer. Helen Mark visits Brendan Little in Donegal to find out about layering. Also on the programme, David goes to an eco-therapy centre in County Fermanagh which is offering horticultural therapy for people suffering with anxiety and depression.
