In a special programme, Carol Klein and Nick Bailey celebrate gardeners throughout the country who have created some truly unique gardens and made every space count.

Carol meets a couple in Dorset whose garden is full of inspirational features, and Nick is in his own city garden, giving his design and gardening tips for making the most of limited spaces. Frances Tophill travels to the Isle of Man to find out how a community of gardeners copes with extremes of weather, while Joe Swift is in Cardiff visiting an extraordinary water-filled front garden.

In Sheffield, one man’s garden is given over to homes for wildlife and we visit a beautiful garden in Essex, the restrained colour palette of which conveys a sense of romance and tranquillity. And, of course, there is plenty of inspiration from our viewers' own gardens.
