I've published an article in The Conversation about the therapeutic benefits of gardening. See the link below:
Here's the first paragraph.
The science is in: gardening is good for you
“That’s all very well put,” says Candide, in the final line of Voltaire’s novel of the same name, “but we must go and work our garden.”
I studied this text at high school before I became a gardener and professional horticulturist. We were taught that Candide’s gardening imperative was metaphorical not literal; a command for finding an authentic vocation, not a call to take up trowels and secateurs.
In fact, Voltaire himself really believed that active gardening was a great way to stay sane, healthy and free from stress. That was 300 years ago.
As it turns out, the science suggests he was right.
There's also a link to my colleague Steven Wells (nurse and gardener extraordinare) talking about his work as a horticultural therapist and garden creator in hospitals.
