Tune into BBC Radio Ulster\u2019s Gardeners\u2019 Corner this Saturday morning when David Maxwell will be discovering how to produce the perfect hedgerow with the clever use of fruit trees as well as finding out how to brighten up the autumn season in the garden with a splash of vibrant colour. He\u2019ll also be speaking to a gardening expert whose green fingers have graced stately homes both north and south of the border and tackling the case of the bountiful blueberry bush in Limavady.
