To celebrate his 50 years as a gardener, Alan Titchmarsh has been on a year-long search for the best back gardens in Britain. Now for the first time in his career he has picked his 30 favourites.

Many of them are gardens that have never been filmed and Alan’s search has taken him from the northernmost point of the UK to the heart of Britain’s biggest cities, discovering people from all walks of life doing amazing things with their outdoor spaces at every turn. So if you’ve ever wondered what’s going on over the neighbours hedge then let Alan take you behind the nations ordinary properties, into a world of jaw dropping sights and sounds.
