Abstract: In the historical process towards ecological civilization and green China, social work focuses on the harmonious relationship between man and nature within the basic framework of interaction between man and environment. Expanding horticultural therapy in social work service is not only conducive to the development of individual body, mind and social relationship, but also conducive to the realization of professional value and social function of social work. Based on the multiple needs of different service groups, horticultural therapy has developed multiple intervention strategies such as therapeutic, occupational and social horticultural models. Through six specific processes, namely activity design, participation in the process, harvest, sharing, life reflection and efficacy evaluation, it has applied and deduced the core methods and technologies such as rooting, implantation and metaphor, and finally promoted physical and mental healing and sustainable development of service clients. Based on historical experience and research reflection, social workers need to adhere to the value concept of green therapy, sustain professional competence, respond to the different needs of service groups, adhere to professional ethics and strengthen risk control in the implementation of horticultural therapy, so as to promote the scientific and localized development of horticultural therapy.
