Summary

A systematic review of 20 randomized controlled trials found that engaging in horticultural activities, such as planting and caring for plants, can significantly reduce depressive symptoms in adults. Most studies showed moderate to large improvements when horticultural interventions were combined with usual care, with participants twice as likely to experience a 50% reduction in symptoms compared to those receiving standard treatment alone.

These findings suggest that horticultural therapy is a safe and effective complementary intervention, with minimal adverse effects and high participant adherence. While results are promising, further research is needed to explore its effectiveness across different populations and settings, particularly among younger individuals.
