Shi, Tong, and Tao investigated the use of gardens by elderly people. They report that “Gardens for the elderly . . . have been revealed to be beneficial to the elderly’s well-being and quality of life. . . . one garden at a care facility for the elderly was studied through total site factor measurement, resident and staff interviews, along with observations. . . . level changes are found to be more influential [on use] than distance and shade.”
