A sense of belonging is a key element in enabling social inclusion through meaningful occupations. This is evident in occupational science and social and therapeutic horticulture (STH) literature. How these theories interact in practice was explored at Thrive's STH project in Battersea in London. A workshop conducted with Thrive Battersea's therapists examined how gardening may facilitate health and wellbeing through belonging. The authors reflect on themes of belonging from the workshop. The implications for occupational therapy from this apparently rich synergy of occupational science, STH and social inclusion are considered.
