Research & Evidence
We have collected studies of therapeutic gardening into a Research Index which can be used to find evidence to support your therapeutic gardening work and funding applications. As further research studies into the benefits of gardening come to our attention we will list them in the Research Index and highlight some of them on this page.
A new feature highlighting research in the field of therapeutic gardening.
In July 2016, a visit to the Trellis office from Maxel Ng of the National Parks Board , Singapore and currently a member of the Visiting Staff at Royal Botanic Garden Edinburgh, brought us news of studies being carried out there, including The Effects of Horticultural Therapy on Asian Elderly’s Mental Health https://www.nparks.gov.sg/~/media/nparks-real-content/news/2016/launch-of-therapeutic-garden-at-hortpark/media-factsheet-b-research-programmes-on-benefits-of-greenery.pdf . So far the results are significantly positive - we’ll link to the full research paper, when it’s published. Singapore has adopted a strategic approach to therapeutic gardening, with direct government investment in gardening projects across the country, see the wealth of gardening and greenspace in Singapore’s culture at https://www.nparks.gov.sg/gardening

Physical Activity and the Prevention of Depression: A Systematic Review of Prospective Studies
George Mammen and Guy Faulkner, PhD shows evidence that any level of physical activity including low levels (e.g., walking or gardening <150 minutes/weeks), can prevent future depression. From a population health perspective, promoting physical activity may serve as a valuable mental health promotion strategy in reducing the risk of developing depression. Published in the

ecotherapy benefits for mental health and wellbeing
Mind (the mental health support charity in England and Wales) recently released Feel Better Outside, Feel Better Inside - a report showing the many benefits of ecotherapy for mental wellbeing. Ecotherapy involves activities such as gardening, food growing and conservation work in natural environments. The report demonstrates that ecotherapy improves mental health, boosts self-esteem, helps people with mental health problems return to work, improves physical health and reduces social isolation. It also calculates the savings to the public purse from engaging people in ecotherapy activities.see report at www.mind.or.uk

Di Blackmore PhD postgraduate student at the University of Stirling gives an update on her research into the health effects of therapeutic gardening.
The main application of the research will be to raise awareness and convince service managers, funders and policy makers in organisations such as national government, local authorities, health and environmental agencies, of the value delivered by such projects.
Green space and Health
Ground-breaking research into the impacts of greenspace, blue space and urban environments on individual and population health was reported at the GreenHealth conference in Edinburgh in March. The conference, organised by greenspace scotland on behalf of the GreenHealth research partnership heard from speakers including Prof George Morris, Prof Richard Mitchell of Glasgow University, Prof Catharine Ward Thompson of the OPENspace Research Centre and Prof David Miller of the James Hutton Institute. In the final session delegates proposed key recommendations for policy, practice and further research. The recommendations, together with the presentations are now available at greenspace scotland
Trellis Research Group
The principal aim of the Trellis research group is to conduct research to build an evidence base that demonstrates the benefits of social and therapeutic horticulture initiatives in Scotland.
In support of these aims, the group intends to:
- Review the available sources of research and evidence in the social and therapeutic horticulture field, classifying the methods, tools and results formulations for use by the Trellis network of projects (e.g. suitability; skills, qualifications and/or training necessary; etc.)
- Sponsor research studies using qualified practitioners and volunteer projects to further develop the Scottish evidence base.
- Publish research study results in professional journals and other related media of good standing worldwide.
- Build a reference base of good practice, consistent standards and information sources to share across the Trellis network (e.g. via the website and other publications.)
- Monitor the policy development of national government, local authorities, health and environmental agencies to ensure continued alignment of the evidence base.
- Work closely with similar groups to exchange findings worldwide.
