Barnsdale Gardens in Rutland, England were made famous by Geoff Hamilton through the BBC television series Gardeners' World which he presented from 1979 until his death in 1996. They are situated on The Avenue in the parish of Exton, a short distance north of Rutland Water.
Geoff Hamilton began developing the garden in 1983 from what was then a ploughed field. It now covers 8 acres (3.2 ha), comprising 37 individual gardens and features.
