Kathy Clugston hosts the horticultural programme featuring a group of gardening experts. This week, Kathy, Ashley Edwards, Pippa Greenwood and James Wong unite to celebrate 75 years of Gardeners' Question Time. Through the mists of time and a smoky room in Ashton-under-Lyne, the team hear a snippet from GQT's first broadcast, reflecting on changing attitudes, and looking toward exciting horticultural developments. From the archive, Eric Robson talks to veterans at the walled allotments in Ayrshire. Producer: Daniel Cocker Assistant Producer: Bethany Hocken A Somethin' Else production for BBC Radio 4
