Older adults are not sufficiently physically active and do not consume sufficient fruits and vegetables to achieve health benefits, such as an improved health-related quality of life (HRQL). As a result, an innovative gardening intervention, comprised of stretching exercises, the teaching of home garden knowledge and skills, and the preparation and taste testing of fruits and vegetables, was developed to target increased: (a) confidence to garden and to consume fruits and vegetables, (b) physical activity, (c) fruit and vegetable consumption, and (d) HRQL. Seven older adults, aged 60 years or older, participated in the gardening intervention and 10 older adults participated in the control group during the fall. Measures of confidence, physical activity (i.e., gardening), fruit and vegetable consumption, and HRQL were obtained at baseline and at the end of the 10-week program. Findings revealed that, at baseline, intervention participants had significantly higher confidence to garden compared to control participants but at end-program intervention and control participants did not significantly differ in any of the outcome variables. Bivariate findings also revealed that intervention participants who had higher confidence to garden or to consume fruits and vegetables at baseline also gardened more at end-program. Thus, interventions targeting confidence to garden and to consume fruits and vegetables may be effective in improving gardening (i.e., physical activity) behavior. Findings also suggest that seasonal change may be one influential moderator of the gardening program on confidence and gardening and fruit and vegetable consumption behavior change. Future research should examine the impact of the program in different seasons to clarify the effects.
