Overview: Alan Titchmarsh and the team are in Barking, where they hope they can coax 90-year-old Iris back into her garden. Since her husband died, the garden has become neglected, but Iris longs to have somewhere to sit and smell the scent of the roses. David Domoney constructs the perfect pathway, while Katie Rushworth sets to work finding a variety of rose which is wildlife-friendly and Frances Tophill creates a summer house full of memories.
