Diarmuid Gavin and his team will be creating the world's smallest garden centre here . . . this we can't wait to see . . . and Diarmuid will be manning the centre at various stages over the next three weeks, with celebrity friends Louise Kennedy, Dave Fanning, Grainne Seoighe and Gerry Ryan. One of the windows will have a kiosk where you can buy everything from garden gnomes to potted plants and wellies and the proceeds raised go towards Temple Street Children's Hospitals.
