Background: Gardening may have multiple physical and mental health tangible benefits. However, gardening has never been fully implemented in healthcare settings prioritising patient care. Objective: This study explored how mental health nurses perceive gardening activities as part of their patient care. Methods: In this descriptive qualitative study, thematic analysis of four focus group discussions (n = 22 nurses) in one psychiatric department in Brunei Darussalam was identified through purposive sampling. Findings: Three key themes arose from the analysis (1) Safeness during gardening, (2) Maintaining the interest, (3) Coordinating the activity. Conclusion: Participating nurses emphasised the perceived challenges of gardening as part of patient care, with a particular focus on patient and nurse safety. Also of concern are the patient's interest throughout the activity, the skills and knowledge of the nurses involved, and the clarity of their roles, especially in coordinating gardening activities. To ensure the garden's long-term viability as part of patient care, developing and reinforcing a guideline that clarifies the roles of nurses and patients is crucial. Future research should focus on patients' preferences and how to engage them in gardening. It is also desirable to examine the possible impact of gardening activities on individuals in psychiatric settings, such as patients, nurses, and other healthcare professionals particularly in establishing clear guidelines.
