BBC Scotland’s acting director Geraldine McCartney paid tribute to McColl.
“His expert gardening advice and wisdom on The Beechgrove Garden was invaluable to green-fingered viewers over the decades and he will be greatly missed by all,” she said.
“Loved by viewers across the nation, he’ll be especially missed in the North East, where he was a much-cherished part of the BBC Scotland and Tern TV teams for many years. Our thoughts are with Jim’s family, friends and colleagues.”
Harry Bell, managing director of Tern TV: “Here’s to ‘our’ lovely Jim, who for four decades presented The Beechgrove Garden for us with a spring in his step, a twinkle in his eye and a kind word for all folk.
“You’ll be fair missed, Jim. You were a local hero first and a Scottish national treasure next. Thank you for your immense contribution to gardening, broadcasting and steering so many of us on life’s muddy paths.”
