She said: "I really believe in the benefits of being outdoors in a living, breathing garden. That’s why I think the work of Thrive is so important.
"When I was 30 I was enjoying a successful music career, with platinum records and a European tour with Michael Jackson under my belt. I decided the time was right to lay down some roots and I moved into a 16th century barn that I renovated and treasured. To the outside world all seemed wonderful, but I was always plagued with anxiety and it badly affected my mental health.
"One in four of us will experience issues with our mental health. Gardening really can help. It has been great therapy for me and can help people get back on top of things and restore balance when it feels like life is veering out of control."
Improving good health and wellbeing is at the heart of the work of Thrive, a national charity with gardens in Reading, London, Birmingham and Gateshead.
