Gardeners' Corner

As the chill of winter bites, David is joined in studio by Ann Fitzsimmons for some timely advice on protecting the garden when the mercury falls. One listener wants advice on ‘Old Man’s Beard’ but this one isn’t wearing a red suit. From Greenmount college to New Jersey – David Wilson on the joy of his horticultural career. At Ballyrobert Cottage Garden, Maurice Parkinson is clearing away the remnants of last season’s growth and putting some of it to good use for wildlife and Tony Kirkham reveals his final ‘Tree of the Month’.
