The designers, who are both studying for a diploma in garden design at Kingston Maurward College, will have the chance to do a practice-run of building their garden borders in Dorset, before they are judged at the NEC in Birmingham on 15 June.
Mike Burks, managing director of The Gardens Group, which has sponsored the pair, has been growing, pruning and caring for their plants in the polytunnels and greenhouses at Castle Gardens, while offering advice and support throughout the process.
He said: "Elle has taken inspiration from Rudyard Kipling, with her plot representing the contrast of vivid colour and smells of India set against his personal traumas, while Julie depicts the famous Winnie the Pooh and the Honey Tree scene from A.A. Milne’s classic children’s books. They have done a fantastic job in designing their borders for the competition and have made some inspired planting decisions to complement their themes. We wish them both the best of luck and we can’t wait to see their borders come to life for the first time on Bank Holiday Monday."
