This week Alan comes to the aid of wounded war hero Luke Simpson who lost his leg to an IED on his last tour of duty in Afghanistan. Luke was in the Royal Engineers when he was injured in an explosion three years ago and has had to rebuild his life and health with the support of his wife Jackie. He's always been a keen gardener but since the incident he's struggled to get the head start he needs to create the cottage garden of his dreams. So Alan and the team rise to the challenge. Along the way Alan gives a master class on that essential plant– the rose, Frances Tophill reveals the key design elements for a cottage style garden, Katie Rushworth tells us how to make the most out of cut flowers, and David Domoney gives hints and tips on how to maintain the perfect lawn.
