Autumn colour, Horatio’s Garden and leaping lizard

David Maxwell will be out and about at Rowallane Garden to find out how to create colour in your autumn garden. David also discovers how the legacy of an intrepid teenager will take root in Belfast in the shape of a charity garden for patients with spinal injuries. And is it an Irish lizard or a newt? – one listener wants to know what she has discovered lurking in the undergrowth. The answer will be revealed on Saturday morning with David Maxwell and the Gardeners’ Corner team.
