Serge Hill Project

In a special programme to mark Mental Health Awareness Week, GQT visits the Serge Hill Project, a garden where working with nature can transform well-being.

In a special Gardeners’ Question Time episode to mark Mental Health Awareness Week, the programme is at the Serge Hill Project, an inspirational garden that promotes working with nature to radically transform people's health and well-being.

Renowned landscape architect Tom Stuart-Smith, and Tom’s partner, psychiatrist, and psychotherapist Sue Stuart-Smith, join regular panellists Pippa Greenwood, Christine Walkden, and Anne Swithinbank to answer listener questions.

The programme also features a generous and brave final appearance from GQT panellist Matt Biggs.

Matt has been a GQT panellist since 1994, and has been battling cancer for six years. Tragically, Matt’s cancer has now entered its end-stage. Matt wanted to record this programme, knowing it would be his last appearance on Gardeners’ Question Time, surrounded by his longtime friends and GQT colleagues.

Listeners will hear questions answered by the GQT panel of gardening experts, but they will also hear about Matt’s journey from initial diagnosis to his current mental and physical condition. At times Matt’s words are upsetting, raw, and honest, however it is Matt’s wish that his story is told partly as advice for other sufferers and also to serve as inspiration to all listeners.

Producers: Dan Cocker, Matt Smith and Rahnee Prescod
Assistant Producer: William Norton

A Somethin' Else production for BBC Radio 4

Now the garden is home to birds, butterflies, bees, hedgehogs, field mice, and a family of foxes, and bats fly overhead at night…They all have their entrances and their exits, and each in his time plays an important part in the pyramid.
