The comments echo those of veteran British broadcaster and gardener Alan Titchmarsh, 77, who has known Charles for four decades and has often toured the King’s gardens with him.
Reflecting on Charles’ accession to the throne following the death of Queen Elizabeth II in 2022, he said: “I’ve walked around his gardens with him on many occasions, but when he acceded to the throne, I was prepared for horticulture not to occupy quite the same place in his heart and daily life. But nothing could have been further from the truth.”
Titchmarsh also praised the King’s contribution to environmental causes.
He added: “The King has done more for horticulture, gardening, natural history and the environment than anybody else, apart from David Attenborough.”
According to Titchmarsh, Charles continues to display remarkable energy despite the demands of both the Crown and his treatment.
He said: “His energy is mind-blowing. He’s enthusiastic, but also pragmatic. The King gets stuck in – he doesn’t just say something should be done, he instigates it.”
The benefits of gardening have long been recognized by mental health experts, who say it is a top distraction from anxiety and negative thoughts.
Charles has championed environmental causes for decades and remains Patron of the Royal Horticultural Society.
He is also supporting the 2026 Curious Garden project through The King’s Foundation, alongside ambassadors David Beckham and Alan Titchmarsh, with the display set to feature at the 2026 RHS Chelsea Flower Show.
