The “coral gardening” approach has been effective in facilitating the recovery of degraded reefs but methodological variations can influence survivorship and growth of the coral material. In addition, the disproportionate use of certain corals, such as acroporids and pocilloporids, has contributed to a general lack of information on growth patterns and restoration strategies for species that are less common. To investigate how the yield of other species may be increased to support reef restoration efforts in Singapore, we assessed the effects of (1) environment (nursery, reef, and seawall) and (2) transplant orientation (horizontal and vertical) on the performance of Echinopora horrida (Dana, 1846) fragments. Fragments secured in the coral nursery grew significantly faster and survived better than those transplanted on the reef and seawall, highlighting the importance of a nursery‐rearing phase in optimizing the yield of this species. Additionally, survivorship and growth rates were not significantly different between vertically and horizontally transplanted corals, suggesting that modifying transplant orientation was less crucial toward enhancing coral yield. Our findings highlighted the need to optimize the propagation techniques of a wider range of understudied coral species in order to preserve their genetic diversity in the face of anthropogenic and climatic impacts.
