There are several definitions of horticultural therapy (HT) contained within literature. It is defined by Zhou (2018) as ‘interventions mediated by nature-oriented views and spaces such as gardens and everything associated with them, the plants and material related to them, for healing and restoring or improving health and wellbeing, or for rehabilitation. HT has both physiological and psychological healing functions and can improve people’s health and happiness’.
Capra and Haller (2016) took the view that ‘horticultural therapy is a professionally conducted clientcentered treatment modality that utilises horticulture activities to meet specific therapeutic or rehabilitative goals of its participants. The focus is to maximise social, cognitive, physical and/ or psychological functioning, and/or to enhance general health and wellness’.
