Gardening and mental health

Claudia Hammond reports on a trend which has emerged from the world-famous Chelsea Flower Show this year - a growing number of gardens designed with mental health in mind. So what is it about gardens and nature which makes us feel better?

The Mothers for Mothers "This Too Shall Pass" garden is designed by Polly Wilkinson - a former counsellor who's worked with adolescents and new mothers with anxiety and depression. The charity's CEO Maria Viner wanted to reflect the joys and pain of motherhood - so Polly constructed a pathway with a crack in it - which narrows and is almost "fixed", echoing the impact that peer support can bring. The lifting of low mood is also seen as muted green and blue flowers give way to apricots and pinks.

Sue Stuart- Smith is a psychiatrist, psychologist and now author of the bestselling book The Well Gardened Mind. She says it's hard to untangle the factors which might be contributing to the impact of nature on us. Dr Stuart-Smith explains how a study in the British Medical Journal found 8,000 studies on the impact of nature - but just 8 were randomised controlled trials. where people are randomly allocated gardening or another activity - so more research is needed.

The mental health charity Mind has its first ever garden at Chelsea this year which will be relocated in Barrow-in-Furness once the show is over. We hear from Alice - who had an eating disorder and obsessive compulsive disorder from an early age - and Faris, who has post-traumatic stress disorder, and sought asylum in the UK after he was orphaned in the conflict in Sudan. They say that growing vegetables and caring for bonsai plants has helped to relieve their symptoms.

The Place2Be garden will also be relocated at the end of the flower show - to Viking School in Northolt, west London. For the last 15 years the children there have been able to get support from the charity's school-based counsellor Miss Angela. CEO Catherine Roche says the garden will provide a safe space so the pupils relax during a busy day. The children helped to design the garden's oak benches with gardener Jamie Butterworth. He says having a mum who's a teacher and a dad who's a mental health nurse made the Place2Be the perfect match for him.
