The Apricot Centre also supports farmers and land-based businesses with nature-based wellbeing therapies and training courses.
The centre said it supported the mental, emotional and social wellbeing of children, young people, families and farming communities.
Amir Qureshy, director of quality assurance at the centre, said nature was the best environment to support people in.
He said: “Most children, young people, families – they’re used to clinical environments, it can be quite intimidating.
“This nature and environment, the connection with nature, we know from research that in terms of anxiety levels, cortisol levels – all of that comes down.”
Qureshy added the prince “lived up to his reputation”.
“He seemed natural in the environment and so from our perspective you know it’s a wonderful connection to make, particularly in terms of his particular special interests,” Qureshy said.
