Alan Titchmarsh and his team take on the challenge of creating a wildlife wonderland complete with a giant pond and rockery in a suburban garden in West Bromwich for local hero fund raiser Pete Hill. Elsewhere in London, Danny takes up Alan's challenge of turning a four-metre wide city backyard into a nature haven complete with living walls and a miniature pond.

Alan Titchmarsh and his team head to Suffolk to transform a garden for charity worker Eileen, who is desperate for a peaceful outdoor space to spend time with her husband Roy, who suffers from Parkinson's. Alan designs an inward-looking intimate area surrounded by beautiful year round colour for Roy and Eileen to enjoy, while Katie Rushworth takes inspiration from their love of pinks and blues to plant a wrap-around border.
