ALAN Titchmarsh, the TV gardener, has complained that people are unable to experience nature because they have become "glued to a screen".
The presenter, 62, said that gardening was "real life" but generations were missing out on it after spending too much time sat in front of TVs and computers.
He also claimed that gardening is more important than politics because "it has a consistent point of view”.
The comments come amid growing concerns that too many young people are failing to experience nature and outdoor play because of overexposure to screen-based entertainment.
In an interview with the Radio Times, Mr Titchmarsh said: “Gardening is more important than politics. It has a consistent point of view. And that is: that a piece of ground should be cherished.”
He added: "If you live in the countryside and look out of the window, you will see there is no ostensible difference between this year and 200 years ago.
"The natural world has a kind of stability. There is a cycle that's reliable and sound, and that is real life to me."
The TV star has written eight novels and hosts an ITV1 chat show but is best known for his gardening programmes, including ‘Gardeners' World’ and ‘How to be a Gardener’.
He said: "There is a greater world out there that people can't see because they're glued to a screen.
"Gardening is the stuff of life. It's about putting a seed in the ground and making it grow."
Mr Titchmarsh was talking to the magazine as he prepares to host his own radio show on the commercial station Classic FM. From this Saturday, he will host a three-hour morning music show.
It follows the cancellation of his Sunday evening show, Melodies for You, after four-and-a-half years on Radio 2.
He said: “I was told Melodies for You wasn’t being recommissioned, and I said, ‘That’s a. shame’, because it had a great following.
“It was a shame, but hey, I’m happy to redress the balance on Classic FM.”
He denies that he is a classical music fanatic but insists his love of the genre goes back to his father.
“My dad had a Fidelity record player,” he said. “It was very posh because you could put the lid clown while playing LPs, which in the 50s was really something. I remember he bought the Ace of Clubs recording of Fingal’s Cave, and Mario Lanza albums. He got me into it.”
