Move over Diarmuid Gavin, RTE is on the hunt for a brand new gardening superstar, and the whole thing kicks off tonight. Five green fingered up and coming garden designers are competing for one very big opportunity: The chance to have their work showcased at this year's Bloom Festival. Armed with a mentor and €5000, the five have just a few weeks to work with a specific garden brief, and only one can walk away with the prize. We're sure the competition will be fierce.
