Therapeutic horticulture (TH) is the participation in horticultural activities facilitated by a registered horticultural therapist or other professionals with training in the use of horticulture as a therapeutic modality to support program goals. It is the process through which participants enhance their well-being through active or passive involvement in plant and plant-related activities. Horticultural therapy (HT) is an active process which occurs in the context of an established treatment plan where the process itself is considered the therapeutic activity rather than the end product.
