In this special Gardeners’ Corner, David Maxwell visits the Eden Project in Cornwall on it’s 20th anniversary to find out about it’s mission to connect people with the planet. He also finds out why Eden is bringing that mission to the banks of the River Foyle. David also meets Fermanagh GP Neil Armstrong who made Cornwall his home in the 1980s, and has spent the last 25 years transforming an abandoned piece of land near Penzance into an exotic paradise. And artist Johns Keys from Belfast on how his artistic eye is transforming Cornish gardens.
